Insecticide Efficacy Against Diamondback Moth, Imported Cabbageworm, and Cabbage Looper Control on Cabbage, 1982:

Cabbage was transplanted Jul 22 at the Vegetable Research Farm near Geneva, NY. Plots consisted of two 10-ft rows, each with 36-inch centers and 16-inch plant spacing. Treatments were replicated 4 times in a RCB design. A 2-row tractor-mounted boom operating at 60 psi and delivering 31 gal/acre with 3 nozzles/row was used to apply a single application to each trial. Agway sticker-spreader (2.5 ml/gal) was added to all treatments. Treatments were applied Sep 9. Evaluations were made on Sep 14 by randomly selecting 3 plants/plot, removing all leaves, and counting the above mentioned species. Infestations were considered moderate.
