Evaluation of Insecticides Against Root Feeding Insects on Transplanted Cabbage, 1980

Cabbage was transplanted on May 1, ’80 in a commercial field in Erie County, Ohio. Two row plots 30’ long on 30” centers with a 12” in-row spacing between transplants were arranged in a randomized complete block design with 4 replications. Treatments were applied on May 2, 1980 with a hand held CO2 sprayer designed to apply a directed spray of 100 gal/acre at 40 psi through a 9505E nozzle. Soil type was a silt loam, pH = 6.2, and organic matter = 2.3%. All treatments were applied only once and were evaluated on June 3, 1980 by digging 20 plants/plot, and counting the number of wireworms, cabbage maggots, and tunnels.
