Insecticide Evaluation for The Control of Japanese Beetle Grubs, 1977

Abstract

Insecticides were evaluated for the control of Japanese beetle grubs on an infested Kentucky bluegrass fairway. A randomized complete block design with 4 replications per treatment (10 x 12 ft) was utilized. Insecticides were applied on September 1, 1977. Sprayable formulations were applied with a hand-hold CO2 powered boom sprayer at 40 psi in 3 gal of water per 1000 sq ft. Granular formulations were applied with a Gandy 36-inch spreader.
