Syngenta Thrive

by


Severely lodged corn can put yield potential at risk. One way or another, however, it must be harvested safely and carefully. Andy Heggenstaller, head of agronomy for Syngenta Seeds, suggests keeping these four factors in mind when harvesting lodged corn.

  1. Go Slowly. If at all possible, avoid speeding through harvest. Rushing quickly through the fields is an inefficient way to harvest lodged corn. Slow your combine speed to reduce the risk of missed ears and be sure to go against the grain to diminish loss.
  2. Set Up for Success. When harvest conditions vary across fields and harvest dates, it’s important to reset the combine before going into a field. For example, you may need to reposition gathering chains on their sprockets so the lugs are directly across from each other to grip stalks more aggressively.
  3. Be Equipped. Make sure your combine is equipped with the proper reel to handle root or stalk lodging. The ideal attachment will lean out ahead of snouts to pick up the plants and effectively guide them into the combine. Many growers intend to rent such equipment when times get tough, but after events like the derecho in 2020, reels quickly become scarce in regions such as east Iowa. Invest in your own equipment now to avoid a headache later.
  4. Keep Quality in Mind. When harvesting corn that’s lying on the ground, quality issues are inevitable. Corn ears that have been in contact with the soil for too long fall victim to a range of toxins that farmers must address. Be on the lookout for additional mold and grain quality loss from ears being close to the ground. Harvesting early helps ensure the stalks are in the best condition possible to aid in getting crop into the head.

No matter what plan you develop for harvesting lodged corn, don’t let yourself get frustrated with the time and effort required. Proper safety practices should always be put in place, as rushing through harvest can be dangerous and counterproductive. With a little preparation and critical thinking, however, you can salvage much of your yield.

Diversity and inclusion programs may focus on opening doors to women and people of color, but they also ultimately drive tangible benefits and opportunities for the entire agricultural industry.

“As agriculture becomes more diverse, more companies are realizing diversity is good for the bottom line,” says Ebony Webber, chief operating officer of Minorities in Agriculture, Natural Resources and Related Sciences (MANRRS). “They see opportunities to expand into new markets and stay competitive.”

MANRRS, which has 2,050 members in 65 chapters across 38 states, promotes academic and professional advancement by empowering minorities in agricultural and related scientific careers. The organization helps members through networking and leadership-training programs. It also provides role models and networking opportunities for student members as early as the seventh grade. A growing number of companies are offering internships and full-time positions to MANRRS members.

“Once our members have the chance for hands-on experiences and realize the opportunities in agriculture, they become more engaged,” says Antomia Farrell, Ed.D., assistant dean and director for diversity, College of Agriculture, Food and Environment, University of Kentucky. She is also serving as the 2020–2021 national MANRRS president and as the University of Kentucky’s MANRRS adviser.

Women are already playing a sizeable role in agriculture. Female-operated farms accounted for 38% of U.S. agriculture sales and 43% of U.S. farmland, according to the 2017 Census of Agriculture.

Joy O’Shaughnessy, chief operating officer, agribusiness, at HighQuest Partners, works with Women in Agribusiness. This group encourages its members to learn about the many career opportunities in agriculture, such as law, finance, insurance, research and more. A part of O’Shaughnessy’s role is working with ag retailers looking to transform their workplaces by hiring and retaining more female employees.

In addition to supporting groups like MANRRS and Women in Agribusiness, agricultural companies can develop their own initiatives. For example, Syngenta recently launched a four-year equity, diversity and inclusion plan. The plan focuses on building diversity and inclusion into senior-level and management teams as well as into employee recruitment, advancement and retention, says Brandon Bell, diversity and inclusion lead at Syngenta, North America.

Webber believes that working together is the key to building greater diversity and inclusion in agriculture. “I hope that as an industry we can become more proactive,” she says. “It’s going to take everyone. But this is a marathon, not a sprint.”

Syngenta researchers fine-tune formulations to meet these challenges. This might mean adding a nonionic surfactant to change the surface tension of a liquid so the droplets don’t bounce off the plant and hit the soil.

For instance, coverage is essential when the goal is weed control. “If you’re spraying small, upright, grass-like weeds, our formulations will stick to the target,” says Mark Ledson, Ph.D., group leader of the lead application technology group in formulation development at Syngenta.

Syngenta works closely with equipment manufacturers to optimize spray nozzles’ effectiveness. “While there haven’t been a lot of new active ingredients coming along, there’s a lot of research going on with nozzles,” Ledson says.

Our goal is to ensure that Syngenta chemistry is applied in the most effective way to maximize efficacy, which leads to higher yield potential and profit potential for growers.

Among the successes over the last 25-plus years of working with equipment manufacturers, Syngenta helped develop the Hypro GuardianAIR with a 10-degree angle for increased spray coverage. The success of the GuardianAIR spurred the creation of the 3D nozzle, whose 40-degree angle outperforms flat-fan nozzles for pre-emergence weed control.

“Our goal is to ensure that Syngenta chemistry is applied in the most effective way to maximize efficacy, which leads to higher yield potential and profit potential for growers,” Ledson says.

Sticky traps allow growers and consultants to monitor adult insect populations for foliar insecticide thresholds. To better manage corn rootworm (CRW) in their fields, corn growers in northern Illinois, eastern Iowa and southern Wisconsin partner with Syngenta to place sticky traps in expected high-pressure areas.

“The project really allows us to showcase what we’re doing to control CRW populations and mitigate insect adaptation,” says Todd McRoberts, agronomy manager for NK Seeds. “When you have growers with no CRW in their fields in high-pressure areas, the results speak for themselves.”

By working with growers who place the traps in their fields, Syngenta learns more about how to use the traps to inform CRW management strategies. The traps also provide population checks in areas expected to have high pressure.

“We work with agronomists and our retailer partners to find growers already engaging in progressive management of their fields,” says Andy Heggenstaller, head of agronomy for Syngenta Seeds, U.Strap. “These growers with multiyear containment approaches are best positioned to benefit from using these traps.”

In some areas, population numbers have exceeded expectations, sparking local awareness campaigns to teach growers and retailers how to best handle the threat that CRW larvae and beetles pose.

The growers who deploy the traps already use several best practices, including crop rotation, trait packages and insecticide treatments. Combined with diligent scouting, these practices help some growers — even those in high-pressure areas — manage CRW populations in their fields.

Assembling an on-farm first aid kit is time well spent, say experts at the AgriSafe Network, a national group of health-care workers and educators who advocate for better rural health. To minimize injuries and save lives, they recommend growers consider investing in first aid kits that account for the unique risks of the job.

What to Include in Your Farm First Aid Kit

Everyday Injuries on the Farm

  • Adhesive bandages — Various sizes and types, including knuckle and butterfly bandages.
  • Alcohol wipes — For cleaning small wounds or insect stings.
  • 1- and 2-inch paper tape on a roller — For easier tearing.
  • To dress wounds —
    • 2-, 4- and 6-inch elastic wraps (with clips, Velcro or self-adhering features).
    • 2-, 4- and 6-inch gauze stretch wraps.
  • Absorbent gauze pads (also referred to as combine dressings) — 4 inch by 4 inch (quantity of 12) and 8 inch by 10 inch (quantity of 4).
  • Large clean cloth — To use as a sling.
  • Large safety pins — To pin a sling or clothing.
  • 2 instant cold packs, sized 5-inch x 8-inch — Know how to properly “pop” them.

Eye and Chemical Safety

  • Two 8-ounce containers of sterile saline — To initially cleanse wounds and for immediate irrigation when accidental chemical sprays, grain particles, etc., enter the eye.
  • Jug of water sealed and stored in a large plastic bag — For eye irrigation and hydration.

Weather and Exposure Protection

  • Emergency/survival blanket (same material as Mylar balloons) — To protect people from the elements and ward off shock.
  • Quilted or heavy “picnic” pad — To serve as ground cover to place someone on who is injured.
  • Insect repellant and insect bite wipes.
  • Hand wipes — For when soap and water are not available to wash hands.
  • Sunscreen (30 SPF or higher).

CPR and Personal Protection

  • 2 pairs of examination gloves, properly sized — To put on if there’s no time to wash hands; they also can protect individuals from contaminated body fluids.
  • CPR face shield — For protection from bodily fluids.
  • Sugar or candy packets, small squeeze tubes of instant frosting — For diabetics who experience a sudden dangerous drop in glucose levels. Do not use chocolate or nuts.

Serious Injuries Involving Machinery

  • Heavy-duty bandage scissors/trauma shears — To cut through denim, jackets, etc., when injury occurs.
  • Sealable 2-quart and 1-gallon plastic bags — For digit amputations.
  • 2 garbage bags with ties — For limb amputations.

After You Build Your Farm First Aid Kit: Prioritize Storage, Access and Training

  • Place them in more than one place so they’re always within reach — no matter where you are on the farm.
  • Store first-aid supplies in water- and dust-resistant containers in easily accessible locations, such as a truck, automobile, tractor, combine, ATV or shop area.
  • Routinely check expiration dates of products.
  • Use caution if you place antibiotic ointments and burn cream in a kit. If you have a wound that requires debridement or possible suturing, ointment and lotion products can greatly hinder that process.
  • Check your community for first aid and CPR classes because an important part of first aid is knowing how to perform CPR accurately.

Flattened and lodged corn plants were strewn across the Midwest in 2020 following various wind events, including a devastating derecho in Iowa. Growers who had intense management programs, including a strong corn rootworm (CRW) offense, realized more successful outcomes than those who did not.

“My plants stayed upright during last year’s wind event,” reports Kyle Van Bogaert, a third-generation corn and soybean grower in Belmont, Wisconsin. “I use crop rotation, insecticide treatments and a seed trait package to combat corn rootworm.”

That multipronged strategy could soon become the standard. Higher-than-normal adult CRW beetle activity in 2020 points to potentially increased pressure in 2021. That’s bad news for corn growers — especially those with corn-on-corn acres — who lose more than $1 billion to CRW damage every year. CRW larvae feed on roots from Colorado to New York, reducing water and nutrient uptake and causing lodging in extreme situations. Adult beetles feed on tassels and clip corn silks, further impacting yield.

But for growers like Van Bogaert who implement multipronged, proactive CRW management plans, fields can see strengthened crops and better profit opportunities. Committing to the multiyear approach needed for management strategies to work can be challenging, but the reduction of CRW root feeding represents a tantalizing reward.

Interpreting Natural Signals

Environmental signals from the previous year will allow growers to plan for potential pressure in subsequent seasons. Wet springs, for example, can kill CRW larvae in the ground, due to saturated soils. On the other hand, dry conditions in May and June create ideal environments for populations to thrive.

With most insect populations, predicting pressure is difficult. The life cycle of CRW, however, offers opportunities to plan control measures. Depending on monitored population levels, growers can begin incorporating insecticide treatments and seed trait stacks into their ongoing planning.

“Through better understanding of the CRW life cycle, growers can anticipate potential CRW populations before they become a problem,” says Meade McDonald, Syngenta product marketing lead for insecticides. “This includes scouting for larval feeding and damage as well as monitoring adult populations.”

Growers can dig corn roots in June to check for larval feeding and damage that can provide clues to coming adult beetle numbers. In July, monitoring populations of adult CRW beetles offers an indication of CRW larval pressure for the following year, according to McDonald. Scouting reports that showed high CRW beetle populations last July are driving expectations of heavy CRW pressure this year.

Working the Bugs Out

A key strategy for CRW management is crop rotation — not planting corn in the same field two years in a row. “It’s the easiest tactic growers can add to the mix of solutions for managing this pest,” says Andy Heggenstaller, head of agronomy for Syngenta Seeds, U.S. “But for some growers, crop rotation isn’t economically feasible, so they have to rely more on alternate solutions.”

The next step for growers to consider is using seed trait stacks — such as Agrisure Duracade® trait stacks — that act against CRW larvae. However, while trait stacks provide ample protection against CRW feeding, growers should consider a multipronged approach in high-pressure fields.

“Especially in corn-on-corn fields, growers may need to deploy multiple management tactics to protect roots, stands and harvestability,” McDonald says. “Growers in these situations should consider a soil-applied insecticide application on top of their trait stack.”

Syngenta offers two Force® brand insecticides to control CRW larvae. The first — Force 6.5G — is a higher-loading granular insecticide than the former Force 3G formulation. Packaged in a 20% lighter bag, Force 6.5G has a more concentrated formulation that allows growers to cover 175% more acres per bag.

Those features helped Van Bogaert handle a planting time crunch in spring 2020. “One bag of Force 6.5G per box covered more than 300 acres of corn at once. We could fill up once and plant all day,” he says. “We have a lot of corn-on-corn growers in our area, and Force 6.5G made a real difference in our fields during the season and at harvest. We will definitely be using it again in 2021.”

The second Force brand is Force Evo insecticide, a liquid formulation with excellent starter fertilizer compatibility. It’s an ideal choice for growers who are injecting starter fertilizer at planting. They can apply Force Evo through a proprietary closed application system developed by Syngenta, with on-farm service and support provided by Direct Contact, Inc.

Paired correctly with a trait stack, Force insecticides can add an average of 10 bushels per acre in yield in high-pressure fields, according to more than 500 Syngenta trials between 2007 and 2017.*

Growers can also use Warrior II with Zeon Technology® foliar insecticide to control adult CRW beetles during summer months. If growers see adult beetles in July, Warrior II with Zeon Technology can minimize tassel feeding and silk clipping, which can dramatically impact yields.

Planning for 2022

When planning for next season, the first product a grower should consider to defend their fields against CRW damage is a Syngenta Bt corn seed trait stack.

Syngenta Bt corn seed trait stacks contain modes of action that target and kill CRW larvae. Agrisure Duracade is the primary Syngenta trait stack for CRW management and contains two proteins that are specifically toxic to CRW larvae when they feed on corn plant roots.

“By combining two separate traits into a plant, Agrisure Duracade delays adaptation to a single technology,” says Todd McRoberts, agronomy manager for NK Seeds. “This preserves yield potential and helps prevent problems years down the road.”

Still, a multiyear approach is necessary for effective CRW management. In heavy-pressure situations, rotating traits every few years can provide another defense.

“Especially for growers who don’t rotate crops, rotating traits may become necessary to prevent entrenched adaptation in CRW populations,” McRoberts says. “Even some growers who do rotate crops may need this tactic in high-pressure geographies.”

Agrisure® 3122 E-Z Refuge® is an excellent alternative trait stack for corn growers using the Syngenta genetic base. It contains a different mode of action plus the Herculex® rootworm trait.

How long growers can use trait stacks depends on local pressure; but if trait rotation is needed, growers should stick to a schedule. Even in lower-pressure seasons, rotating traits can help preserve trait durability.

There is no catch-all treatment for CRW, and planning for this pest spans years instead of months. But by finding the right mix of agronomic practices, seed traits and insecticides, growers can fight back against even the heaviest CRW infestations.

Q: What are some of the most typical health challenges or injuries on a farm in the spring?

A: David Merrell, M.D., occupational health physician, Syngenta: According to the Centers for Disease Control and Prevention, the National Ag Safety Database, and the Association of American Medical Colleges, agriculture workers in combination with workers in forestry and fishing have the highest fatal injury rate at 23.4 deaths per 100,000 compared with 3.5 deaths per 100,000 for all other U.S. industries*. The most common injuries on a farm stem from machinery maintenance activities, with the most fatal injuries involving tractors overturning or running over the individual.

Regardless of the type of injury or illness, one of the greatest health challenges confronting American farmers today is having access to available, affordable and convenient health care. This challenge results from distance to a health care provider’s office, lack of accepted medical coverage, as well as lost time and wages incurred from traveling for care. Studies show a steady decline in the number of medical offices serving rural communities. This trend leads to fewer office visits and a decline in overall health outcomes. Generally, rural communities carry higher rates of death from heart disease, cancer, unintentional injury, chronic lower respiratory disease and stroke.

A: Knesha Rose-Davison, public health program director, AgriSafe Network: In the spring, some of the most typical health challenges on a farm are injuries and illnesses that stem from working with livestock and calving. These include infectious diseases transmitted from animals to humans as well as injuries that result from needle sticks and working with large animals.

Spring is also the time that growers are emptying grain bins, so maintaining respiratory health and avoiding grain bin accidents that could lead to suffocation are top priorities. Additionally, warmer weather can bring more stress to farmers as they start planting their crops, so maintaining good mental health is important.

Q: What can growers do to safeguard themselves and others against these conditions?

A: Merrell: Education and perspective are key. Knowing how to safely operate and maintain a piece of equipment is critical to one’s safety. Growers can accomplish this goal by making sure they regularly review operating and maintenance manuals and follow safety guidelines. Injuries most often occur when farm workers use machinery outside of normal operating procedures in an effort to “get a job done.” Remembering the potential cost of an injury — life, limb, lost time working — can help prevent the urge to work outside of what is considered safe and can reduce the potential for harm.

Telehealth decreases travel time, time lost from work and school, and lag times for diagnosis and treatment, which can improve outcomes and decrease stress.

A: Rose-Davison: Growers can safeguard themselves, their workers and their families by assessing the potential risks and hazards associated with upcoming tasks and work sites prior to busier times. For example, farm owners can schedule safety talks with their workers about protocols to follow to avoid injury. A part of this is making sure all workers have ready access to the personal protective equipment they may need, such as respirators approved by the National Institute for Occupational Safety and Health, eye protection, Tyvek® suits or coveralls, and gloves — all sized correctly and stored properly. To reduce stress, it’s important for growers to get enough sleep, have a healthy diet and stay safely connected to their social networks. They can expand their safety and health knowledge by visiting agrisafe.org and participating in one of our free training webinars.

Q: What role can mobile or telehealth medicine play in meeting the medical needs of today’s farm family?

A: Merrell: Routine medical examination can prevent many of the leading causes of death and disability — heart disease, cancer, unintentional injury, chronic lower respiratory disease and stroke — among rural communities. Mobile medical clinics can serve a broad rural community with regular exams and screening labs to help detect and prevent these ailments. Due to the high potential cost of visiting a physician at a faraway location, telehealth can provide a good option for triaging a medical issue to determine whether a more significant intervention is needed. Telehealth saves both time and money for those in rural communities. Limited access to the internet due to inadequate broadband service is an issue in many rural communities. Many farm groups and companies, including Syngenta, are advocating for increased government investment in this critical technology.

A: Rose-Davison: The COVID-19 pandemic created opportunity, decreased hesitancy and improved reimbursement for telehealth faster than we ever imagined. While not every medical visit is telehealth appropriate, when it is, there are obvious benefits for farm families. Telehealth decreases travel time, time lost from work and school, and lag times for diagnosis and treatment, which can improve outcomes and decrease stress. For behavioral health treatment and counseling, eliminating travel creates opportunities for more frequent follow-ups, which are key to assessing safety and behavioral changes. Video and audio telehealth improve access to medical specialists often not available to farm families in their communities. Some of these specialty fields include behavioral health, chronic disease management, post-surgical services, cancer treatment counseling and health education.

Year in and year out, professional athletic clubs spend millions of dollars looking for just the right talent to add to their lineups, fill skill gaps and win more games. Much like the athletic scouting process, Syngenta researchers are on a quest to find just the right tools to more effectively fight disease and, ultimately, help growers achieve higher returns. To that end, Syngenta has introduced two game-changing fungicide molecules for the row-crop market in the last three years—Solatenol® fungicide and most recently, Adepidyn® fungicide.

''

In laboratory and field tests, Solatenol and Adepidyn fungicides have proven to provide the best-of-the-best disease control and plant-health benefits of any fungicide available.

Eric Tedford, Ph.D.

Not All SDHIs Are Created Equal

While both Solatenol and Adepidyn fungicides fit into the carboxamide chemical class with an SDHI (succinate dehydrogenase inhibitor) mode-of-action chemistry, they have their own characteristics that set them apart from each other—and every other fungicide on the market.

“In laboratory and field tests, Solatenol and Adepidyn fungicides have proven to provide the best-of-the-best disease control and plant-health benefits of any fungicide available,” says Eric Tedford, Ph.D., Syngenta fungicide technical product lead. “In 2019, Adepidyn will be available in multiple custom-designed fungicides under the Miravis® brand to combat geospecific disease threats that growers face.”

Row-Crop Diseases Meet Their Match

New and shifting disease patterns as well as resistance continue to drive the need for innovative technology.

“We’ve put together a robust row-crop fungicide portfolio to allow growers to choose the formulation that fits their specific disease problems,” says Brett Johnson, Syngenta fungicide product lead. Knowing the strengths of each brand will be crucial to selecting the best fungicide for 2019.”

Syngenta has a winning roster of fungicides. Grower Mark Forsyth of Charles City, Iowa, sprays his soybeans with Trivapro fungicide to effectively manage diseases. He also uses Trivapro on his soybean acreage.

The Syngenta row-crop fungicide portfolio will include the following brands:

Trivapro® fungicide—With first sales in 2016, Trivapro quickly proved its ability to work harder and last longer to fight diseases and help improve plant health for higher yields, versus untreated acres and competitive brands. Powered by three active ingredients—azoxystrobin, propiconazole and Solatenol fungicides—Trivapro has set a new standard for residual disease control for rusts, blights and leaf spots in corn, soybeans and wheat.

“Over the last few years, Trivapro’s consistently long residual control and yield bump have impressed my customers and me,” says William “Bill” Ruzicka with Farmers Feed & Grain in Riceville, Iowa. “In our side-by-side trials where other brands have petered out late in the season, Trivapro keeps protecting crops, which makes it worth the investment.”

One of his customers who has seen these benefits firsthand is grower Mark Forsyth from Charles City, Iowa. “I’ve been using Trivapro for three years now to control Northern corn leaf blight and gray leaf spot,” he says. “We started off with one field, and now we treat all our acres with Trivapro, because of the consistent stay-green effect and yield bump of 10 to 15 bushels per acre, sometimes more, depending on the hybrid.”

While Trivapro controls many diseases, efficacy ratings from university corn fungicide trials rank its Southern rust control as excellent—an important distinction for growers who face Southern rust pressure. Over the last few years, University of Kentucky Plant Pathologist Carl Bradley, Ph.D., has observed yield losses caused by Southern rust in Kentucky cornfields. “We really don’t have any corn hybrids with complete resistance to Southern rust, so application of an effective fungicide is really the only current method of management for this disease,” he says.

Forsyth checks out a couple of ears of corn on his farm.

Miravis Neo fungicide—Similar to Trivapro, Miravis Neo will help corn and soybean producers combat disease by offering unmistakably superior control from three active ingredients: azoxystrobin, propiconazole and Adepidyn fungicides. Miravis Neo offers the most potent control of blights and leaf spots and will offer a new tool for white mold in soybeans.

Tedford notes that Miravis Neo has benefits beyond robust disease control. “In both lab and field tests evaluating crop stress responses, plants treated with Adepidyn have demonstrated more vigor,” he says. “That means under stressful conditions—like drought or heat stress, or even under light disease pressure—Miravis Neo–treated plants can put all their energy toward yield.”

Ruzicka, who had a chance to field-test the new technology this year, is looking forward to more widespread use of this exceptional product in 2019.

Miravis Top fungicide—Engineered specifically with Southern soybean growers in mind, Miravis Top contains difenoconazole and Adepidyn fungicides. With two powerful active ingredients, Miravis Top enables growers to control diseases—including susceptible and strobilurin-resistant frogeye leaf spot, target spot and Septoria brown spot—while providing the plant-health benefits they expect.

“Unlike some of the older chemistries growers have used before, both modes of action in Miravis Top will be working to protect their yield from disease,” says James Hadden, Ph.D., Syngenta fungicide technical product lead. “In our trials evaluating control of target spot, Septoria and strobilurin-resistant frogeye leaf spot, we’ve seen anywhere from a 3 to 5 bushel-per-acre yield increase with Miravis Top over competitive brands.”

In addition to outstanding disease control, Miravis Top will help alleviate the growing threat of disease resistance, Bradley says. “We all know about strobilurin-resistant strains of the frogeye leaf spot fungus,” he says, “and we have confirmed cases of strobilurin-resistant strains of the Septoria brown spot fungus. It’s really only a matter of time before we find and document strobilurin-resistant strains of the target spot fungus, too.”

Growers shouldn’t overlook the importance of having a new active ingredient to help combat growing resistance challenges, Bradley adds. Currently, control of frogeye leaf spot is coming from the triazole component of most fungicide products, since the fungus has exhibited widespread resistance to strobilurin fungicides. This is making the triazoles do all the “heavy lifting” and sets up a scenario where resistance to triazole fungicides could eventually develop as well. Using new chemistries from different chemical classes will help sustain management of frogeye leaf spot with fungicides for a longer period of time.

Miravis Ace fungicide—Wheat growers have long battled Fusarium head scab (blight) with relatively few modes of action and constrained application flexibility. In 2019, that situation will change with the introduction of Miravis Ace.

Containing Adepidyn and propiconazole, Miravis Ace will not only be the first SDHI-containing product available for Fusarium head scab control, but it will also be the first new mode of action for the disease in many years. Field tests across the country—from North Dakota to Pennsylvania and Kentucky—demonstrate that Miravis Ace will enable wheat growers to have more flexibility to treat all their acres at the right time for better, more predictable results.

In field tests, Syngenta has demonstrated that Miravis Ace can be sprayed as early as 50 percent head emergence, without sacrificing efficacy or yield. And because it delivers excellent control of Fusarium head scab, Miravis Ace can help reduce levels of the profit-robbing mycotoxin deoxynivalenol, also known as DON or vomitoxin.

A Tailor-Made Portfolio

With the introduction of the Miravis brands, row-crop growers now have four potent fungicides to choose from to fight the specific diseases that threaten their crops, Johnson notes.

“Unlike the repackaging and rebranding of old technology we’re seeing in some products, these brands contain game-changing molecules,” he says. “Solatenol already has completely changed row-crop disease control and plant-health protection as we know it, and Adepidyn will soon follow suit. Once growers try these products, they won’t go back.”

Growers, get ready for the next big transformation in farm technology—the driverless tractor. After two decades of building on a precision platform that started with GPS navigation, farm equipment manufacturers are getting close to realizing the much-anticipated milestone of having fully automated tractors on farms.

Right now, the driverless tractor still needs an operator, whose role is to intervene frequently to keep the tractor on task. But the ultimate goal is to offer growers driverless equipment that is smart—or autonomous—so they can perform tasks without human intervention. In other words, the driverless tractor would act as its own operator.

This goal requires equipment with sensors and cameras to relay data to onboard computers, which need artificial intelligence, so they can instantly respond to anything affecting the equipment’s current task. The technology will require minimal outside help.

Driverless tractors will allow growers to monitor field operations remotely from their computers.

Race to Autonomy

While the farm equipment industry has spent a couple of decades moving toward developing autonomous equipment, the race to commercially market that equipment has recently moved into high gear.

“Key farm manufacturers are all working in some way on autonomy,” says Dan Halliday, global product manager of precision land management at New Holland Agriculture. Niche companies and after-market suppliers also are developing autonomous solutions, which adds pressure across the industry to keep moving ahead, he says.

In 2016, both New Holland and Case IH introduced autonomous tractor prototypes, which the companies are still testing in the field.

“We’ve done a lot of work since then,” Halliday says. “We are working on sensor technology to make the driverless operation viable. And we launched smart auto-turn features last year.”

But there’s still work to be done, he adds. “There are applications that will need more work before we can fully automate them. If you want to till a field, it’s relatively easy to automate. However, if you’re combining, there’s a lot more going on.”

John Deere signaled its commitment to autonomous machinery when it acquired Blue River Technology. Blue River specializes in computer vision and machine learning, which are key technologies for developing task-oriented autonomous equipment.

“Frankly, we know that the move toward autonomy is about more than just a tractor driving across the field,” says Than Hartsock, manager of production system solutions at John Deere. “The quality of the job that the implement is doing matters, because that’s what ultimately impacts the crop that’s being grown. It’s not just the combine, but also the header that really matters. We are focusing our efforts on sensing, controlling and automating those functions.”

Blue River’s work on an advanced sprayer system illustrates the potential of automated technology. Computer vision allows the sprayer to sense the environment around it and look for weeds. The machine learns through artificial intelligence to identify weeds from soybeans, and then it precisely sprays individual weeds. This labor-free operation uses a minimum of chemicals and captures crop data to document the entire process.

''

Autonomy takes out potential human error and gives the user a choice to operate overnight or for 24 hours. Clearly growers can benefit from increased efficiency on their farms utilizing these technologies.

Dan Halliday

The Digital Component

The ability to capture data from autonomous machinery will benefit farmers, according to Dan Burdett, global head of digital agriculture at Syngenta.

“The driverless tractor and automated farm equipment will be able to record any field event, which is important for developing insights, such as calculating return on investment [ROI],” he says. “Capturing timely and accurate data to document field applications for reports and stewardship requirements will also be possible.”

Because various sensors, tools and artificial intelligence will automate data collection, Burdett says the data will “enable a whole new level of decision-making capabilities. Growers will benefit from all of it.” He says the adoption of digital technologies in the ag industry is inevitable and moving fast.

“It’s escalating, and that’s driven partly by farm economics,” he says. “It’s very important for farmers to know their numbers. Digital tools and information technology can help farmers be better business people.”

Also driving the move to digital is a demographic change. “There are younger growers coming back on the farm who have a different way of doing things, including how they make decisions for the farm,” Burdett adds. “They do much more online research and consume a lot more information than previous generations.”

The Future of Autonomy

For many years, the high cost of components needed for autonomous vehicles was partially responsible for ag manufacturers not bringing the vehicles to market. But that is changing.

Uber, Google and Tesla have made big investments in technology for their self-driving cars. This development has substantially lowered the cost of some components that are also used in automated farm equipment.

“We are seeing tremendous progress and innovation in cameras that are more capable and less expensive,” Hartsock says. “The sensors they use to look for obstacles in the road are becoming more effective and less expensive, too.”

As more industries use these components, prices will further drop, making autonomy within reach of farmers.

“We continue to see farmers who want products that make them money in a safe environment and that make fieldwork easier,” Hartsock says. “And as circumstances continue to compromise viable labor in our industry, farmers will need this help. All of these technologies make things easier and often have a substantial ROI for farmers.”

Autonomous and semi-autonomous equipment also may do the job better. “Autonomy takes out potential human error and gives the user a choice to operate overnight or for 24 hours,” says Halliday. “Clearly growers can benefit from increased efficiency on their farms utilizing these technologies.”

For more than 50 years, U.S. corn, sorghum and sugar cane growers have depended on atrazine herbicide to produce food sustainably. They trust that its safety and efficacy are well documented, as are its environmental, economic and production benefits.

In fact, atrazine is one of the most closely examined herbicides in the world. “This herbicide has gone through a tremendous amount of scientific testing, both with regard to managing its risks and measuring its benefits,” says Jay Vroom, president and CEO of CropLife America. “I doubt there is any compound used in agriculture—or anywhere else in society—that has been more thoroughly evaluated on its presence in surface and groundwater and its potential effects on wildlife.”

Toxicologist Timothy Pastoor, Ph.D., who spent much of his career at Syngenta studying atrazine, agrees. “When I talk about the science behind atrazine, I talk about the more than 7,000 studies that support the registration, which is far more than any other active ingredient on the market,” he says. “Atrazine is inexpensive, and it works. It’s the all-star of agriculture.”

Atrazine Advantages

All of that research has brought to light atrazine’s many benefits. For example, without atrazine, crop yields would potentially diminish, making U.S. growers less competitive compared with other global producers.

“If you significantly reduce yields, you’ll likely drive up production acreage,” says David Bridges, Ph.D., president of Abraham Baldwin Agricultural College. “Well, there’s not a lot more acreage out there that’s prime farmland, so what do you do? You put marginal acreage that is currently in conservation programs—protecting streams and wildlife habitat—into production, which has negative consequences for the country as a whole.” Research shows that using atrazine helps keep an average of 513,000 acres in a noncrop scenario, allowing for more biodiversity on this acreage.

On farmed acres, atrazine helps reduce soil erosion by enabling no-till farming and conservation tillage. “Atrazine gives growers residual weed control, so they’re not having to do deep plowing every year, reducing soil and pesticide runoff,” says Dennis Kelly, head of state affairs at Syngenta. “Without atrazine, the fields may not be no-till any longer, and that’s going to decrease water quality due to increased sediments, especially in sensitive watersheds.”

According to studies, some 3 million dump trucks worth of soil are kept in place each year because of atrazine. Less plowing also means less petroleum burned, which means less carbon dioxide emitted.

Atrazine is highly selective and inhibits photosynthesis in weeds, while corn is very tolerant. According to Bridges, “It tends to make other corn herbicide products even better, leading to more than 60 prepackaged mixtures with other herbicides in the market.

Farmers know that when they apply a product containing atrazine—of which there are more than 60—they’re going to get the broad-scale weed control they’re looking for.

Economics Upsides, Production Pluses

Atrazine is crucial economically, too. According to studies, the use of atrazine supports 85,000 jobs across the ag industry. It also means a boost of more than 900 million bushels of corn output each year.

Without atrazine in their toolboxes, growers would feel the financial implications quickly. “It makes a $34 to $48 positive difference per acre for a corn grower,” says Bridges. “When you’re talking about farmers with a couple thousand acres, that big difference in weed control and yield protection results in a large increase in their bottom lines.”

As one of the few herbicide modes of action available to growers, atrazine offers another benefit to growers, notes Ethan Mathews, director of public policy for the National Corn Growers Association: “It’s one of the last lines of defense we have against weeds that are resistant to other herbicides.”

It’s, therefore, not surprising that growers and herbicide manufacturers alike often turn to atrazine for more effective weed control. It’s frequently sold in combination with newer active ingredients because it makes those products work better. “Other active ingredients might not have the span of weed coverage that’s necessary for the farmer; the addition of atrazine gives the product formulation the span of activity farmers are looking for,” Pastoor says. “Farmers know that when they apply a product containing atrazine—of which there are more than 60—they’re going to get the broad-scale weed control they’re looking for.”

Strong Grower Support

Given atrazine’s central role in the production of corn, sorghum and sugar cane, it’s understandable that concerns were raised last June when the Environmental Protection Agency (EPA) released an unfavorable preliminary draft ecological risk assessment on the herbicide. In response, the scientific and agriculture community submitted hundreds of thousands of comments in support of the product.

“The retailer and grower response and support were amazing,” Kelly says. “We believe that once EPA reviews the overwhelming evidence on the safety of atrazine, it will make changes to its assessment and farmers will be able to continue to use atrazine.”

Although EPA’s public comment period for that draft has concluded, the agency’s review process is ongoing. Next, EPA will review the provided information, amend the draft report as appropriate, and hold a Scientific Advisory Panel (SAP) meeting. Then the agency will publish a preliminary reregistration decision and ask for further public comment.

In addition to all the public comments, EPA will consider the volume of data that atrazine has on its side. “It’s one of the best-studied, most extensively regulated molecules on the planet,” Pastoor says. “Thousands of scientific studies have demonstrated that, when used properly at the labeled rate, atrazine has not, will not and, in fact, cannot adversely affect human health.”
