Early Season Control of Thrips in Cotton, 1992:

Abstract

Cotton was planted on 21 May at the Eastern Shore Agricultural Experiment Station, Painter, VA. Each treatment consisted of 3, 25 ft rows with an untreated border row separating treatments. Row spacing was 36 inches. Each treatment was replicated 4 times in a RCB design. Orthene 15 G and Temik 15 G were applied in the furrow before planting using a hand-held shaker. Orthene 75 S foliar sprays were applied on 8 Jun using a single nozzle hollow cone boom backpack sprayer delivering 15 gal water/acre at 40 psi. The second spray for the Orthene 75 S split application treatment was made on 22 Jun. Evaluation criteria consisted of height measurements and percent thrips injury ratings on the dates indicated in the table.
