Control of Citrus Bud Mite and Citrus Red Mite in Orange Co., 1981

Abstract

Abstract Materials were tested for efficacy against citrus bud mite in a lemon grove near Irvin, California. Treatments were applied on Sep 16 by handgun (450 psi) with about 1500 gal per acre. There were four two-tree replicates and pre-treatment levels varied from 48.8 to 71.3 percent buds infested. Five buds on each of four terminals were dissected for each of the replicates, and the percent buds infested was calculated. At the time of treatment, there was only a trace of citrus red mite; the population was monitored on a few trees and at 100 days post-spray a rating of all trees was made.
