Demonstrating New Technologies for Improved Corn Rootworm Management

Abstract

On-farm demonstrations were initiated at the Cornell Musgrave Farm, Aurora and the Cornell Teaching and Research (T&R) Farm, Harford, to present, compare, and evaluate new and emerging corn rootworm (CRW) management strategies. In this second phase of a three year project, two ca. 0.7 acre field sites (Musgrave Farm field “X” and Animal Science Teaching and Research NYSEG field) were planted to a corn rootworm resistant (Bt transgenic) hybrid and a non – transgenic hybrid receiving one of the following treatments: no soil insecticide (control), conventional soil insecticides: Force 3.0 G, Lorsban 15G or Counter 20 CR, insecticide seed coatings: Gaucho (seed corn maggot rate), Prescribe (CRW rate), or TI-435. Treatments were compared for relative corn rootworm protection.
