Jon Tollefson, research entomologist, and Jim Oleson, agricultural specialist, published a 2002 report that evaluated the performance of a variety of control measures for corn rootworm larvae. One of the products they evaluated was the recently approved YieldGard® Rootworm corn. In their tests, the seed was treated with Gaucho ST as a preventive for seed-attacking insects such as seedcorn maggots and wireworms. The in-field performance of YieldGard Rootworm in protecting the plant from corn rootworm injury is going to be one of the critical factors determining its acceptance in the agricultural community.
