Flea Beetle Control, 1996

Materials were applied on 6 Jun to 20 by 20 ft plots in a bearing blueberry field at Jonesport, Maine. There were 3 replications of each treatment and a minimum 5-ft untreated buffer strip around each plot. Treatments were blocked according to prespray population levels. Insecticides were applied at a rate of 25 gpa using a CO2-propelled 80-inch boom sprayer with 4, flat spray, 8OO02VS TeeJet nozzles operating at 35 psi. At treatment, plants were ca. 50% loose cluster, 50% bloom. On sample dates indicated in table, 10 sweeps with a standard 12-inch sweepnet were taken systematically through the center area of each plot, avoiding plot boundaries. The larvae were counted and then distributed back into the same plot. No unusual weather conditions were noted during this test.
