Citrus Red Mite Pesticide Efficacy Tests in the San Joaquin Valley, 1983

Acaracids were tested for control of citrus red mite populations in two tests in the San Juaquin valley, near Ivanhoe, Calif, and at the Lindcove Field Station, near Exeter, Calif, respectively. In Test 1, materials were applied at 100 gal-acre using an FMC 267 speed sprayer driven at 2 mph. Each material was applied to a 2-acre plot with 10 trees chosen initially at random from the plot and monitored on each sample date. In Test 2, materials were applied using a Hardie hand gun and John Bean sprayer at 500 lb/in2 thorough distribution coverage at approximately 15 gal per tree with six single-tree replicates per material. For both tests, naked-eye counts of adult female mites on 32 leaves per tree (two, four-leaf terminals per quadrant) were made.
