Alfalfa and soybean trouble observed

The University of Minnesota Southwest Research & Outreach Center in Lamberton reports that there is an alfalfa weevil dilemma in some southern Minnesota alfalfa crops, and the bean leaf beetle for soybeans is also causing trouble.

Crop specialist Bruce Brown said that when weevil populations are threatening but crop damage is not severe, growers must decide whether to cut or to use an insecticide. If great yield loss has already been incurred, management increasingly shifts to salvaging any remaining first crop yield and minimizing impacts on the remaining cuttings.
