Demonstrating New Technologies for Improved Corn Rootworm Management
Waldron, J. Keith; Shields, Elson J.; Cox, W.J.
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 third year of a continuing project, two ca. 0.7 acre field sites (Musgrave Farm field “X” and Animal Science Teaching and Research NYSEG field) were planted to corn receiving one of the following treatments: no soil insecticide (control), conventional soil insecticides: Force 3.0 G, Lorsban 15G or Counter 20 CR, and insecticide seed coatings: Gaucho (seed corn maggot rate), Prescribe (CRW rate), or TI-435. In addition to these treatments used in previous years, a second check (no soil insecticide with a fungicide seed treatment), and the soil insecticides Aztec 2.1, Capture 2EC, and Regent 80 WG were added. Treatments were compared for relative corn rootworm protection. Year 3 objectives have been completed and a summary of activities is presented.
