Granular Insecticide Whorl Applications to Cabbage, 1976

This test was conducted at Agway Farm Research Center, Fabius, NY, to correlate the performance of a controlled release insecticide formulation, Orthene, by measuring the total degree of insect feeding injury and percent insect control. A randomized block design of 3 replications was used with 24-inch row spacing (21/780 linear feet of row/acre) in a plot of 5 x 30 ft. Two hundred lb of 20-20-20 was fall applied and disced in; Dacthal 75W herbicide was applied at 12 lb/acre preemergence. White cabbage of the variety ‘Penn State Ballhead’ was direct seeded with model JD-37 seeder June 10, 1976, and insecticide applications were made postemergence August 24, 1976. A hand-held shaker can was used to deliver premeasured granular insecticide amounts per plot over the tops of plants. At this time the cabbage was approximately 12 inches high with the first several head leaves formed.
