Multiple Modes and of Action and Residuals Needed for Effective Weed Control

Another planting season is near and so is another season of strategizing Indiana corn and soybean field weed control and minimizing weed resistance to herbicides. A clean start this spring is the best way for those fields and seeds to minimize fighting with weeds and provide maximum yields.

“Weed resistance is an ongoing problem and in Indiana, especially marestail, giant ragweed, waterhemp, boy you guys hit the jackpot with these tough weeds,” says John Foresman, herbicide product lead with Syngenta.

He says the best start this spring is a clean start.

“Make sure that you have a clean seed bed, whether it’s a burndown program that includes a strong herbicide like Gramoxone, or else tillage. You want to start clean. You want to select products or a tank mix that has multiple modes of action. A lot of people talk about rotating chemistry and so forth, but what’s really important is using multiple modes of action with the applications that you make and using the proper rates.”

Foresman says residual herbicides are also a must to maintain clean fields.

“Yiou have weeds coming up at planting time or even before planting, like marestail coming up in the fall, and then you get to planting time. Unless you clean those up you’ve got to deal with them, but then you have weeds that will emerge all the way into June, and so you have to have residual. There’s no other option. You have to have residuals because farmers don’t have just one weed in their field. They’ve got a whole number of weeds.
