ONION THRIPS CONTROL, 2001

ONION THRIPS CONTROL, 2001 (E53) ONION: Allium cepa L., 'Teton' Robert W. Hammon and Melissa L. Foley Colorado State University Western Colorado Research Center 1910 L Road Fruita, CO 81521 Phone: (970) 858-3629 Fax: (970) 858-0461 E-mail: rhammon@lamar.colostate.edu Onion thrips: Thrips tabaci Lindeman The experiment was conducted in a commercial onion field near Delta, CO. Plots were arranged in a RCB design with four replications. Treatments were applied with a hand held CO pressured sprayer calibrated to apply 15 gpa of spray material through four Teejet 8002 VS nozzles at 45 PSI. Spreader sticker (Activator 90, Loveland Industries) was added to all treatments at a rate of 1.5 pt/100 gal. Plots were 15 ft in length by three 30-inch beds. Five random plants were chosen from the center bed of the plot on each sample date, and thrips were counted in the field. Treatments were applied twice at 7 d intervals (14 Jun and repeated on 21 Jun). ANOVA was performed on the data and means were separated using LSD (P = 0.05). There were no significant differences between treatments on the 7 and 21 DAT sample dates, although the untreated check plots had apparent larger thrips counts than any of the treated plots. All treatments reduced onion thrips counts on the 13 DAT sample date, with Lannate LV, Vydate L, and Warrior EC providing the best level of control. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Arthropod Management Tests Oxford University Press
