For small grains, wild oats are especially problematic. NDSU Extension Crop and Weed Sciences Associate Professor Kirk Howatt has been researching control methods for wild oats. These methods often lean toward more soil-applied herbicides. “The triallate works best if we apply it in the spring so there’s less time for it to break down,” said Howatt. “With spring applications, though, you really need to incorporate them mechanically to get into the top inch-and-a-half of soil so that wild oat shoots pick it up when coming through the soil and are controlled.”
