Potato Insect Pest Control with Systemic Insecticides, 1985

‘Russet Burbank’ potatoes were planted on 18 Apr at the j University of Idaho Research and Extension Center, Caldwell, ID, in Vickery-Marsing silt loam. Plots were 2-row, 20 ft long separated by 3-ft borders of ‘Red Pontiac’ potatoes in a randomized complete block design with 6 replications. Insecticides were applied broadcast, in-furrow at planting, or in a 10 inch band. Those chemicals applied broadcast or in a 10 inch band were applied by hand, then soil incorporated. Counts for aphids and the CPB were made weekly by examining 10 leaves per plot. CPB damage rating was from 0-3, with 0 being no visible damage and 3 severe damage. Wireworm damage was assessed at harvest by examining 50 tubers from each plot.
