Vayantis Fungicide Seed Treatment Receives Registration To Protect Corn From Pythium

The U.S. Environmental Protection Agency recently granted federal registration to Vayantis^® fungicide seed treatment. The new registration gives corn growers access to the new systemic fungicide seed treatment picarbutrazox, the most intrinsically active compound ever developed to protect corn from Pythium* — the No. 1 seedling disease threat in corn.

With a completely new mode of action, Vayantis will be available in select areas for the 2021 growing season and is expected to be available nationally for 2022 planting.
