Abstract
Abstract An experimental potato planting (’Kennebec’ variety) was made on Mar 26 at Moreno Valley Field Station, Riverside, CA. Insecticide treatments were replicated 3 times in a randomized complete block design. The replicates were 21 rows wide (32 inch centers) by 75 ft long with a 5 ft buffer between replicates. Insecticides were applied at 2 wk intervals from Jun 3 through Jul 15 (4 applications). Insecticides were applied by a tractor-mounted back boom sprayer with 1 nozzle per row at an operating pressure of 100 psi and delivery rate of 20 gal/acre. Nozzles were hollow cone, D3 orifice, 25 core and 50 mesh screen. All treatments included 0.04% spreader-sticker (Biofilm). Ten stems/replicate were inspected weekly from Jun 10 through Jul 7 for larvae and mines. The center 2 rows/replicate were harvested on Jul 22. Data were analyzed by DMRT at the 5% level of probability. An arcsin transformation was performed on mean percent infested white and light green tubers and mean percent total infested tubers before analysis.
