Some new herbicides received late Environmental Protection Agency (EPA) registration while other products were only test marketed in a few Midwestern states last year by manufacturers. As a result, there’s not a large number of new herbicides for controlling weeds in no-tilled corn this year.

One of the hot topics at the National No-Tillage Conference held in Cincinnati was corn herbicides. Sara Gehant, technical support representative, Syngenta; David Lamore, technical service representative, Aventis CropScience; and Paul Sprangle, agronomy research manager, Monsanto; addressed issues on combatting corn weeds and introduced seven new products.
