What Type of 2025 Grower Are You?
Take this fast and fun quiz to find out what type of grower you are.
Answer these six questions to find out how you’ll rule the field in 2025.
Just like you, weeds, pests and diseases are waiting anxiously to see what conditions next season brings. No matter the weather, one or more will be ready to battle your corn crop. Having a strategy that prepares your crop to face any opponent in any condition will tip the odds of a winning harvest in your favor.
Your corn crop’s first challenger is early-season weed pressure. Make sure your weed management strategy includes a timely application of a residual preemergence herbicide with an overlapping postemergence residual and multiple effective sites of action.
“Early-season weed control is about effective control, which is necessary for high-yielding corn crops,” says Travis Gustafson, Syngenta agronomist in Nebraska. He explains that if corn emerges next to a weed, it will orient its leaves to avoid the competition. This leads the corn to instead compete with its neighboring corn plants as it grows.
“Additionally, in a weed-free field, corn will shade the row faster, gather more sunlight throughout the growing season, and ultimately be a healthier, more productive plant,” he says.
An effective preemergence residual herbicide also provides a longer window for young corn plants to establish healthy root systems free of weed competition. If corn emerges to weed pressure, it will grow quickly to get above it, sacrificing root growth.
“If a dry spell hits later in the season, a crop that competed with weeds early will have less root mass to take up water and nutrients and be under more stress than a plant that had a clean field from the start,” says Nick Groth, Syngenta agronomist in Wisconsin. “Corn plants need to have a good day every day from planting through harvest to maximize yield potential.”
Corn plants need to have a good day every day from planting through harvest to maximize yield potential.
For some weeds, it’s even more critical to make sure they never see the light of day. Palmer amaranth caught some producers off guard last season, Gustafson says.
This heavy hitter can knockout corn yields — losses have been shown to reach 91 percent in corn1. Palmer amaranth plants can produce up to 100,000 seeds per plant, grow quickly, and are prone to developing resistance. It takes discipline to defeat this opponent.
“We can’t take a wait-and-see approach with tough weeds like waterhemp, marestail and Palmer amaranth,” says Gustafson. “In my area, once the weed is up, it’s nearly impossible to kill. Producers can’t cut corners on residual herbicide.”
Groth says producers in his area are having to adjust their thinking as they face waterhemp.
“Waterhemp isn’t like every other weed they’ve faced throughout their career. They can’t spray it over the top once it’s up and expect it all to die,” Groth says. “Growers should plan an aggressive herbicide program to stay ahead of it, and you don’t want to fall behind and risk developing a resistance problem.”
Choosing the correct residual herbicide is just as critical as following label instructions and making timely applications at full recommended rates.
“The key to having an effective program that is resilient to varying weed spectrums is using an herbicide with multiple, effective sites of action targeted to key driver weeds for optimal control and resistance management,” Groth says.
Choosing a corn herbicide like Storen®, for example, delivers two sites of action and four residual active ingredients, including the unique component bicyclopyrone, which is also included in Acuron® corn herbicide. These options consistently deliver high levels of weed control, Groth says.
Using the higher recommended labelled rates of residual herbicides can be a make-or-break decision when facing tough weeds. The residual needs to hold out until the field is fit for the next herbicide pass.
“You need to control the weed seed, not the weed itself. Bolstering rates and getting as much residual control as possible in the soil will be critical going forward,” Groth says.
Late-season foliar diseases are tough to predict since pressure can vary season to season. Some growers take a “wait and see” approach with disease outbreaks, but that could mean losing out on plant-health benefits or losing yield to late-emerging diseases if they don’t apply a fungicide.
Wet conditions in 2024 had producers in Groth’s region rightly concerned about tar spot. Many applied fungicides. In areas where it hit, producers saw great benefit. There were a lot of areas, however, where tar spot didn’t develop. In those areas, growers that used Miravis® Neo fungicide, part of Syngenta’s Cleaner & Greener fungicide portfolio, still saw a yield bump thanks to its proven plant-health benefits.
“Using a fungicide like Miravis Neo that controls a broad spectrum of diseases and delivers plant-health benefits allows producers to get a benefit from that application and a return on their investment in a wide variety of scenarios,” Gustafson says.
Plant-health benefits can help corn overcome stress like excessive heat and lack of moisture. They keep the corn crop greener and healthier longer, absorbing more light to produce more yield. Healthier crops use water more efficiently and have stronger stalks to reduce lodging at harvest.
Groth says producers shouldn’t wait for diseases to appear. Instead, they should plan to apply a broad-spectrum fungicide with plant-health benefits between tassel and R1-R2 every year to get the best long-term return on investment from a fungicide program. At this critical point, pollination and fertilization are occurring. Any additional stress on the crop can reduce the number of kernels per ear, kernel size and yield potential.
“We just don’t know what will happen after application. It might stay wet, and disease becomes an issue. Or it might turn dry and you need to rely on plant-health benefits. Some years it will be a home-run and other years a moderate ROI will be maintained,” Groth says.
Weeds or disease, corn producers should go into the season with a solid crop protection plan in place. Being aggressive early in the season can help head off problems that could otherwise tank profit per bushel.
With weed control, waiting too long or not using a product with a long enough residual can mean a costly additional application.
“Cleanup options for weeds like waterhemp aren’t always effective and they’re definitely expensive. It is best practice to apply two timely passes of a herbicide to make sure the crop doesn’t struggle with competition” Groth says.
For disease control, using a product at R1 that sticks around longer to provide more protection spreads the value of that investment over more days. Trivapro® fungicide and Miravis Neo have the longest residuals on the market for tar spot and Southern rust, diseases that had pockets of heavy pressure in corn-producing states in 2024. They also mitigate stress from variable weather to help keep fields cleaner & greener.
“When you don’t have to make another application, the cost per day of weed control goes down. In other words, the longer the residual is, the less expensive the cost per day of protection will be,” Gustafson says. “At the end of the day, you’re providing excellent crop protection and increasing bushels produced at the end of the season.”
For farmers, “spring fever” tends to manifest as restless energy to get into fields as soon as possible. After all, there’s lots to do, and weather often limits the time to do it.
Research shows planting soybeans early, before corn, has higher potential to increase yield and profit. But that can also increase the risks of planting soybeans into poorer conditions.
Pythium is one of those risks. A water mold, this group of fungal-like organisms live in most soil types or on crop residue as oomycetes that can survive for up to 10 years. When wet soil conditions and the right temperatures trigger the Pythium life cycle, they produce swimming zoospores that infect soybean seeds and roots, as well as some weeds and rotational crops.
University researchers note that Pythium species in the northern U.S. tend to infect plants when temperatures range from 50 to 60°F, while most species found in the South activate under temperatures between 85 and 95°F. In short, various Pythium species are active across a broad temperature range as long as there is moisture in soil pore spaces.
The pathogen causes damping off both before and after emergence. Pre-emergence, Pythium can prevent germination or cause seeds to rot; Post-emergence damping off is caused by Pythium killing young seedlings. Both types can lead to reduced yields associated with reduced plant stands. Under favorable conditions, Pythium can infect soybeans within 90 minutes of planting. It can be activated by stretches of wet weather between soybean planting and emergence.
The resulting poor stand establishment can require replanting, meaning you could miss out on the benefits of planting early in the first place. In 2023, university pathologists estimated that U.S. soybeans lost about 5.9 million bushels of yield to seedling diseases, including Pythium.
As soybeans grow, they become less susceptible to Pythium infections, so management practices that promote germination and growth help minimize yield loss.
To limit the risk for replants and maximize your seed investment, consider a premium F/I seed treatment like CruiserMaxx® APX. Powered by novel active ingredient picarbutrazox, along with second mode of action Apron XL, CruiserMaxx APX offers the most powerful Pythium protection available in a seed treatment premix. In addition, CruiserMaxx APX also helps safeguard soybeans against Phytophthora, Rhizoctonia, Fusarium, bean leaf beetles and other early-season pests.

Two factors indicate an insect’s ability to survive the winter: their biological adaptations to cold and a hospitable place to settle in to keep from freezing. If they hunker down successfully in your field, they’ll be in place to start feeding and breeding as soon as seeds are in the ground.
Because insects are unable to create their own body heat, three primary types of adaptation allow them to emerge in spring fields for another season: freeze avoidance, freeze tolerance, and “insect hibernation” or diapause.
Freeze-avoidant insects produce antifreeze proteins in their bodies as the cold moves in, allowing them to acclimate to the cold and survive sharp drops in temperature. Freeze-tolerant insects produce nucleating proteins that accumulate in their hemolymph — a fluid similar to blood in humans — which cause ice crystals to form in the hemolymph instead of the cells, where they would be lethal to the insect.
Diapause is a metabolic slow-down, regulated by hormones and genetically triggered to take place during a particular life stage. It’s effectively a state of suspended animation, during which growth and development slow and the insect’s resistance to extreme conditions increases. Extended diapause is what allows Northern corn rootworm to beat the corn-bean rotation by “sleeping” until corn is on the menu again.
For soil dwelling insects, the most dangerous phase of development is often the larval stage when insects are hungry and preparing to pupate. Soil boring insects feed on plant roots or, in the case of cutworms, tender plant stems. In addition to feeding damage, the insects can spread disease through the crop as they move from plant to plant. They’re also most vulnerable to pesticides as larvae.
Since growers can’t count on the cold to kill off all the insects in their fields, integrated pest management (IPM) is a grower’s best approach against those that survive, according to Matt Geiger, agronomy service representative for Syngenta in south central Illinois.
“You should do multiple things to control your pests, not just one,” Geiger says. “You want to manage the vegetation in and around your fields and use good traits in conjunction with crop protection and seed treatments.”
A good time to scout is after harvest, when egg masses on dead plants, tree bark, and other sheltered locations are easier to see. Cultural controls against overwintering insects include tillage, which can disrupt habitats by incorporating field residue into the soil, destroying insect eggs laid in field stubble, and compacting the dirt, potentially crushing or trapping insects in the ground. Insects unearthed by tillage are also more likely to be exposed to predators or sudden severe weather they can’t bounce back from.
Crop rotation is another way to separate a pest from its crop of choice, as many corn growers learned after battling corn rootworm. In addition to depriving them of their food source, rotation can subject the insects to conditions they aren’t equipped for.
On the chemistry side, Geiger says clean fields are crucial even in cold weather, since insects, including cutworm moths, mate and lay eggs from early spring to late fall.
“In corn, you really don’t want to let a bunch of weeds go in the winter because cutworms could lay eggs in the weeds or potentially in a cover crop,” he says, noting that vegetation left in a field also serves as insulation for the insects beneath it.
“That insect can clip corn plants off at the ground if you don’t use traited corn. You should also have an insecticide like Warrior II with Zeon Technology® mixed with your corn residual herbicide pass.”
“When cutworms crawl across the ground, that insecticide will absorb into their bellies and kill them before they can clip the plants. Every farmer should be using a soil-applied insecticide if cutworms are a risk for their geography.”
On the seed side, Geiger says, DuracadeViptera™ corn trait stacks feature a unique mode of action that controls corn rootworm differently than others on the market along with offering protection against cutworms, earworms and rootworms.
“The most devastating insects are overwintering in the soil — corn rootworm, wireworm — those are big problems,” Geiger says. “If you’ve got those, you need to have an IPM strategy, for sure.”

Strawberry crown and red stele root rots are both caused by soilborne oomycetes Phytophthora—Greek for “plant destroyer”—and specifically P. fragariae in red stele rot. Because the pathogens thrive in wet soil, a planting site with good drainage and no history of disease will give strawberry plants an early advantage in the field.
According to University of California IPM (UC-IPM), symptoms of crown and red stele rot include plant stunting, small leaves, brown to black roots, and brown discoloration of the crown tissue. Red stele rot indicators may also include a lack of vigor, short runners and small berries.
Because above-ground appearance of plants can mimic other diseases, diagnosis of crown or red stele rot requires removing the plant to assess the crown and roots. Infected crowns may separate from the roots as the plant is unearthed, and a vertical cross-section of a diseased crown will reveal brown discolored tissue.
Symptoms of red stele rot first appear on plants located in low, poorly drained parts of the field. Splitting an affected root above the rotted end will expose red coloration in the core of the root. Lateral roots are often rotted, and new crown roots develop a “rat tail” appearance as they die back from their tips.
Cultural controls to manage crown and red stele rot include planting in raised beds and carefully managed trickle or drip irrigation, rotation with non-host crops, and solarization of the soil. UC-IPM says soil solarization in hot months helps kill disease-causing organisms including oomycetes, nematodes and weed seeds, and makes nutrients more available to crops by speeding up the breakdown of organic matter. Consider planting resistant varieties if possible, especially if you have a history of crown or red stele rot on your farm.
Preventive fungicide applications are recommended for strawberry crown and red stele rots. Curative applications have been found far less effective, according to The American Phytopathological Society.
Orondis® Gold DC supports strong early strawberry plant establishment and healthier roots. By helping prevent crown rot and red stele root rot, these options can help early strawberry crop establishment and promote root health.
Water droplets, whether from rain, dew or irrigation, bring valuable moisture to crops. But their splash can also spread disease spores quickly. Plus, high humidity and moisture levels contribute to favorable conditions for those spores to infect plants.
Diseases like downy mildew and gummy stem blight can drastically reduce yields in cucumbers, melons like cantaloupe and watermelon, summer and winter squash, pumpkins and other gourds. These costly diseases often require prevention or very early detection. Vigilance and a program that includes cultural and chemical controls can help growers protect these high-value crops.
A water mold caused by the pathogen Pseudoperonospora cubensis, downy mildew overwinters on host plants in the southern United States and Mexico or in greenhouses. According to Cornell Cooperative Extension, wind can carry the spores hundreds of miles and spores from infected plants can be spread via water splash to nearby plants.
The spores are viable for just a week or two, but they can infect cucurbits under favorably moist conditions between 40- and 80-degrees Fahrenheit. Symptoms start as irregular spots on leaves that vary in shade and shape between host species. When conditions favor disease spread, the lesions on the underside of the leaves will have a “downy” appearance that varies from gray, brown and purple in color. Infected leaves may also curl.
Farmers can monitor the movement of this disease with alerts from the Cucurbit Downy Mildew IPM Pipe website. Using this and other tools can help determine if a preventative treatment is needed. In some regions, planting early may allow for harvest before downy mildew becomes a problem.
The fungal pathogen Didymella bryoniae causes gummy stem blight when it infects leaves and stems, named for the gummy brown substance that comes out of lesions. When it infects fruit, it causes black rot. It survives season to season in crop debris in the field. Unlike downy mildew, gummy stem blight is primarily moved by rain or irrigation from crop residue to growing plants, where the pathogen enters through wounds.
Symptoms start once you see cankers on stems and vines or browning at leaf edges, and further infection signs vary between cucurbit species. Crops infested with insects or other diseases experience higher rates of gummy stem blight because of the minor wounds they create.
Crop rotation can reduce the risk of infection. Wait two to four years before planting any cucurbit in fields experiencing gummy stem blight or black rot.
Integrated management recommendations for both downy mildew and gummy stem blight, like those from NC State Extension, help growers manage these pests which can otherwise be costly both in yield loss and treatment.
Depending on crop and region, growers can choose varieties with resistance to either disease. When starting with transplants or cuttings, ensure the plants are healthy and haven’t been infected.
If signs of either disease are present when scouting, remove infected plants. Keep leaves drier and create less favorable conditions for disease development by utilizing drip irrigation and planting to improve airflow.
Preventive strategies provide the best management of downy mildew and gummy stem blight, especially if environmental conditions are right or your fields have a history of disease. Under favorable conditions for development, fungicides may be required.
Applying fungicides at recommended intervals, usually seven or 10 days depending on the crop and disease threat, can prevent or manage infections. Rotating fungicide modes of action between each application and choosing options with multiple active ingredients reduces the risk of these diseases developing resistance.
Consider the following options as part of a robust fungicide rotation to protect cucumbers, melons, squash, pumpkins and gourds:
Your fungicide program should be tailored to address both the primary disease problem and any others that may be present in the field. Work with an agronomist and your local Syngenta representative to confirm that active ingredients used in each application work with different modes of action.
Maintaining a sustainable farm operation means that growers continue to learn and adapt to a changing agricultural landscape. The Cropwise™ Sustainability mobile app now incorporates the Cool Farm Tool (CFT) to provide growers with actionable insights to understand and find opportunities to reduce the greenhouse gas (GHG) emissions of their operation. The integration is rooted in the Sustainable Outcomes in Agriculture (SOA) Standard developed by Syngenta to measure continuous improvement in farm sustainability. CFT offers growers the opportunity to provide up-to-date information on their efforts toward reducing GHG emissions.
CFT, created by the Cool Farm® Alliance, is a new calculator feature within Cropwise Sustainability that helps a farming operation measure its greenhouse gas emissions and overall sustainability. The tool provides an additional report and analysis that shows the operation’s farm-level carbon emissions and their sources.
Steven Wall, development manager for sustainable and responsible business at Syngenta, says the CFT was chosen because of the long relationship Syngenta has with the Cool Farm Alliance.
“The Cool Farm Tool is well recognized globally. We’re members of the Cool Farm Alliance, and we’ve used it in different facets in different countries for many years,” he says. “Growers can share the data they get from CFT with their buyers, which helps the buyers meet their commitments.”
Jeff Lail, senior data analyst for digital ag solutions at Syngenta, is also a fan of the Cool Farm Alliance.
“The Cool Farm Alliance is based on the International Panel for Climate Change. Its documentation is excellent and publicly available,” he says. “The Alliance was started by academics, and they’re transparent and easy to work with.”
The seamless integration of CFT and Cropwise Sustainability means users don’t have to venture outside of the Cropwise Sustainability app to determine their carbon calculations, which lowers the pain point of data reporting. Lail says the digital ag team sought ways to make the technology as easy to use as possible.
About five years ago, I heard a farmer say, ‘Assessing my sustainability is a business requirement, not an option.’ We seek ways to make this activity as efficient as possible for growers.
The CFT calculator available in the Cropwise Sustainability app is suitable for a range of growers, including those who are new to on-farm sustainability tracking and who are interested in understanding the GHG emissions associated with their farm. The CFT calculator provides more detailed information about carbon emissions that can be provided to buyers.
“We heard from growers that sellers started asking about their farms’ sustainability impact. That’s the primary reason why we added the tool to Cropwise Sustainability,” Lail says. “Although the CFT incorporated into Cropwise Sustainability is a simplified version of the program, we feel it gives growers a solid estimate of their carbon emissions and helps them evaluate their operations.”
The CFT asks many of the same questions growers already answer as part of the Cropwise Sustainability assessment, making it a simple integration for growers. In total, growers only need to answer about three additional questions.
Syngenta’s digital ag team conducts regular surveys to gauge grower interest in new features and to enhance the user experience, so Cropwise Sustainability will continue to evolve to meet the needs of growers.
“About five years ago, I heard a farmer say, ‘Assessing my sustainability is a business requirement, not an option,’” Lail says. “We seek ways to make this activity as efficient as possible for growers.”
Healthy pollinators and a biodiverse landscape are essential to every agricultural ecosystem. Threats to pollinator populations are due to many factors, like habitat loss and fragmentation, non-sustainable agricultural practices, environmental pollution and lack of genetic diversity.
Syngenta leverages key partnerships and collaborations to further its mission to support American farmers and their land and vital pollinators for successful crop production and biodiversity.
Crop protection products, including neonicotinoids, are essential in the agriculture industry. These products help prevent and treat diseases, fight insect pests, increase overall crop yield and help ensure growers can continue to maintain and grow the U.S. food supply at a sustainable rate. Since 2019, the BeSure! campaign — led by Growing Matters, a coalition of ag companies including Syngenta — promotes best stewardship practices to protect pollinators when using neonicotinoid products on farms and urban landscapes. Growers should:
The pollination efforts of bees contribute nearly $20 billion to the value of crop production in the U.S. each year. Native bees are important for biodiversity and play an important role in pollinator services for crops and native plants including wildflowers. One species, the rusty patched bumble bee, was listed as endangered in 2017 making it the first endangered bee species in the continental U.S.
Syngenta, the Iowa Soybean Association and the U.S. Fish & Wildlife Service, along with Iowa landowners, joined forces on the Rusty Patched Bumble Bee Habitat Restoration Project to help protect the declining species.
The project established pollinator zones, which is marginal land converted into beneficial habitats for pollinators, and prairie strips, which are native prairie plants that are strategically placed to improve soil, water quality, biodiversity and climate resilience. The initiative created more habitat for rusty patched bumble bees, other pollinators and local wildlife to thrive, leading to a tenfold increase in rusty patched bumble bee populations since 2019.
Preserving habitats is essential for safeguarding the well-being of wildlife and biodiversity, forging a direct link between conservation practices and sustainable agriculture. Habitats face many challenges such as land use conversion, invasive plant species and limited diversity of native grasses and wildflowers.
Pheasants Forever and Syngenta partner to conserve habitats and promote sustainable land management practices. By working closely with farmers, ranchers and landowners, they enable projects ranging from planting native grasses and wildflowers to restoring wetlands.
Pheasants Forever’s Pollinator Habitat Outreach Program provides tools, training and financial assistance for local communities to establish habitat projects for pollinating species. In 2023, the program engaged 3,727 participants across 64 acres.
Milkweed in the Classroom is an education program dedicated to providing students with the materials and training needed to grow native plants. The initiative has involved 3,353 participants across 146 classrooms to plant 7,560 milkweed stems.
Syngenta’s repeated and growing financial support over the past four years has helped Sand County Foundation continue our program in three states and expand the program into two new states in 2022. We aspire to grow the program further in the future to include additional states in the Midwest and beyond.
Not only are pollinators essential to agriculture, they’re also necessary to maintaining natural habitats and plant biodiversity. Through Sand County Foundation’s Pollinator Habitat Grant Program, agriculture and science educators can apply for grants online and partner with local landowners to create or enhance habitats for pollinators. Selected schools receive native wildflower seed and seedlings, a training webinar and consultation as well as a $1,000 grant for the school district or FFA chapter for project expenses.
Since the program was launched in 2017, 103 high schools have been awarded grants across Minnesota, Iowa, Wisconsin, Michigan, Illinois and Texas, engaging 11,000 students to plant more than 64,000 wildflower plugs. Sand County Foundation surveyed students who had completed projects supported by the grant program and found that over 95% of the students reported that the experience raised their awareness of how important pollinators are to the health of our agricultural system.
“Syngenta’s repeated and growing financial support over the past four years has helped Sand County Foundation continue our program in three states and expand the program into two new states in 2022,” says Craig Ficenec, program director of Sand County Foundation. “We aspire to grow the program further in the future to include additional states in the Midwest and beyond.”
You wouldn’t fill your gas tank half full and expect to go the same number of miles as a full tank. The same applies to your herbicide program. Using the full-labeled rate is one of the most important factors towards having a successful weed control outcome. This approach extends residual control helping to prevent weeds from emerging late and going to seed.
Every season, you plant your crop into soil that contains weed seed deposits from weeds left uncontrolled in past seasons or carried in by equipment, animals or the environment. If you didn’t achieve effective weed control in past seasons, your weed seed bank will contain extra weed seeds just waiting to emerge and compete with your crop.
Waterhemp seeds can remain viable in the soil for several years, with studies showing that 12% of seeds can persist in the soil, even after four years of burial.1 Other weed species can survive even longer in the soil seed bank, which is why it’s important to know which weeds you’re battling in each of your fields.
Broad-spectrum, preemergence residual herbicides and residual herbicide programs are available to help control weeds before they emerge and have a chance to produce weed seed. However, these herbicides will only perform at their maximum level — and give you the most value — if they are used at the full-labeled rate designed to deliver a successful weed control outcome. Before a second flush of weeds can emerge, follow up with a post-emergence residual herbicide to help achieve overlapping, season-long residual weed control.
“Using a full rate of preemergence residual herbicides like Acuron® or Storen® for corn or Tendovo® for soybeans will give you greater consistency, so you can get more weed control, more often,” says Mark Kitt, technical product lead of corn herbicides at Syngenta.
These three jars contain varying amounts of waterhemp seeds, and you can see that herbicide application rate affects the number of weed survivors and the weeds seeds they can produce, according to Kitt.
* If an overlapping application was not made to manage the survivors.
It’s important to remember that applying full-labeled rates supports sound herbicide resistance management practices. Then, you are able to more effectively control weeds by controlling the weed seed, and not just the emerged weed.
Using a preemergence residual herbicide at a full-labeled rate can also boost yield potential. If the emerging crop doesn’t have to compete with weeds for key nutrients like water, nitrogen, phosphorus and potassium needed for crop growth, more yield potential will be protected.
Using a full-labeled herbicide rate also means you can expect to get the complete duration of a product’s residual activity. While many herbicides last four to six weeks, Storen corn herbicide, when applied at its full-labeled rate of 2.1 – 2.4 qt/A, has been proven to deliver residual control that can last up to three weeks longer than other leading corn herbicides.7
“It’s important to remember that applying full-labeled rates supports sound herbicide resistance management practices,” Kitt says. “Then, you are able to more effectively control weeds by controlling the weed seed, and not just the emerged weed.”
