Furdan Versus Counter As A Planting Time Rootworm Insecticide in Cornfields Having A History of Furadan Usage, 1976

Planting time applications of Furadan and Counter insecticides were applied to cornfields for rootworm control at 12 locations in eastern Nebraska in 1976. All fields had a history of annual applications of Furadan for the 3+ years prior to 1976. In 1975, 6 of the fields (1-6) were judged by the authors to have unsatisfactory rootworm control. Insecticide treatments were applied over the row in a 7 inch band (incorporated by drag chains and a following rake) at 1.2 oz a.i./lOOO ft of row. Design was randomized complete block with 4 replications excepting locations 1 and 3, (3 rep). Location 4 (2 rep) and location 12 (8 rep).
