The test area was part of a spring seeded stand of “Buffalo” alfalfa. Compounds for evaluation were applied on 6 July 1983 to 40 by 40 ft plots in 16.5 gal/acre at 40 lb/in2 using a tractor-mounted boom-type sprayer with 8002 flat fan nozzles and 50-mesh screens. Conditions at treatment were 85°F and no wind. Alfalfa was 12 in. tall. The experimental design was a randomized complete block design with untreated checks in four replications. Samples consisting of 10 (180-degree) sweeps with a 15-inch sweep net, were taken pretreatment, 24 h, 7 and 14 days posttreatment to evaluate potato leafhopper control.
