Proper use of new herbicide-tolerant systems
“The application academies are only part of an overall stewardship effort,” said Bowe. “We have two big areas that we are trying to stress. One is on-target application and the other is weed resistance management. Both are really hot topics, and they are really serious matters for growers.”
He went on to say, “We want to make sure that dicamba is used in an overall system, or plan, for managing weeds, and that includes going back to basic agronomics to make sure a crop is as competitive as possible, and with herbicides, that includes making sure to use residual herbicides, mixing and rotating herbicide modes of action and having a diverse weed control program.”
“Dicamba is going to be a very valuable part of cropping systems; there is a real need for it, but we don’t want it to be abused. It has to be used intelligently like any of the herbicide tools that we have available.”
Herbicide resistance is something that Bowe and BASF representatives are stressing in discussions with growers and ag retailers. The company doesn’t want growers using a postemerge application of the new dicamba and glyphosate alone.
Bowe said, “If you only have two modes of actions that are active on a weed species, and the weed is resistant to one of those herbicides, then the second one is the only one effective against the weed. That is not a strong strategy, and that is why we are working with university researchers developing resistant management strategies that provide effective control but are durable and not focused on the use of only two herbicides.”
