Selected Seed, Hopper Box and In-Furrow Insecticide Treatments for Control of Tobacco Thrips in Peanut, 1992:

Abstract

Abstract Efficacy of planting time insecticide treatments was evaluated against TT injury in Virginia-type peanut in Suffolk, VA. Peanuts were planted 11 May with 36-inch row spacing. In-furrow (IF) treatments were applied into the seed furrow at planting, granules using a tractor-mounted Noble applicator, liquids using a CO2 pressurized tractor-mounted sprayer calibrated to deliver 5 gal/acre at 24 psi through 1, SS8001E flat fan nozzle per row mounted just above planter disks and turned parallel to row direction. Hopper box treatments were applied at planting. The planter box was filled ½ full of seed with ½ the measured amount of product (dry) sprinkled evenly over the surface and gently mixed. The hopper box was then filled and the remainder of the product was sprinkled over the surface and gently mixed. Seed treatments were applied by gently rolling seeds in a plastic bag containing product until seeds were evenly coated. Some seed treatments (indicated by *) were commercially applied. A randomized complete block experimental design was used with 4 replicates; plots were 4 rows by 30 ft. Treatments were evaluated by determining plant injury based on a 0-10 scale where 0 = no TT injured leaves and 10 = 100 percent leaves injured. Data were analyzed using ANOVA and LSD procedures.
