North Dakota is in the peak of spray season for soybeans and dry edible beans, later than usual due to the slower weed germination. “As we move to the vegetative stages and toward reproduction, about every spray rig was out in the last week trying to control weeds,” said Joe Ikley, weed management specialist, NDSU Extension. Dicamba products were still used in North Dakota this season. “The majority of the calls I’ve received is from people pleased with the residual activity from dicamba in the Xtend soybean system. We typically don’t talk about dicamba as a good residual product, because it is water soluble. We get most of our rains in June and that can make that activity go away quickly, but when it stays dry, that’s enough to get the product to be active on small weeds.”
