Abstract
Abstract An existing spider mite infestation was located in a grower’s field on June 3, 1975. Plots of 3 rows (36 inch spacing) by 12 ft length were established in a randomized block design with 4 replicates. Sprays were applied over the row in a 10 inch band with a CO2 regulated, knapsack sprayer calibrated to deliver 18 gal/acre at 50 psi. Efficacy counts were made on 10 randomly selected leaves (40 leaflets) from the center row of each plot. All growth stages were counted at 72 hours and 22 days after treatment.
