Abstract

Abstract Cotton was planted on 25 Apr in an AutryviUe loamy fine sand near Richlands, NC. Recommended agronomic practices for fertility and weed control were followed and 0.675 lb (Al)/acre Temik 15G used at planting for thrips. A RCBD was used with 4 replicates and 6-row (38 inch centers) X 45 ft plots with 10 ft alleys. Treatments were applied with a back pack, CO2-pressurized sprayer calibrated to deliver 8.0 gpa at 50 psi with one TX-8 hollow cone nozzle per row. Applications were made on 19 and 24 Jul and 7 Aug. One hundred squares and 100 bolls (25/plot) were examined on 2 Aug and 100 bolls on 21 Aug for damage and live BW and FAW. Plots were harvested with a 2-row John Deere mechanical harvester on 9 Oct. Insect data were subjected to ANOVA and DNMRT (P = 0.05).
