Several miticides were evaluated for their ability to control citrus flat mite on oranges in Yuma, Ariz. The orchard had sandy loam soil; pH 8.1 and 0.15% organic matter. Applications were made 24 Aug. Temperatures at the time of application were 87-101°F, relative humidity peaked at 38% and wind was 3-5 mph. Treatments were applied with a handgun from a John Beam sprayer operating at 300 psi at a rate of 225 gal/acre. The experimental design was completely random with single-tree plots and 4 replications. Mite counts were made on the basis of 40-fruit samples, 10 from each plot.
