The purpose of this study is to evaluate various pre-emergent herbicides to determine their success in controlling weeds and their impact on yield.

Combating weed resistance by using multiple modes of action in your residual program is extremely important. In cool, wet springs however, injury from Group 14 PPO herbicides can be evident. Group 14 and 15 herbicides provide us with longer lasting weed control, especially on tough to control weeds. Minimizing injury can be done by planting at the label’s recommended depth and making sure the seed trench is closed properly. As you can see from this study, controlling weeds is more beneficial than losing a few plants early in the season.
