University of Minnesota Extension Crops Educator Angie Peltier spoke at the series of Small Grain Update meetings. “Ragweed is one of the earlier emerging weeds in our cropping system and the most important and vulnerable point in any weed life cycle is the seed stage.” In the integrated weed management trial, pre-emergence herbicide applications are key to reducing yield loss, even with early-season weeds like ragweed. “Then, for those later emerging weed species like the waterhemps and the Palmer amaranths of the world, we need to stick with that sort of strategy to attack when they’re at their most vulnerable.”
