Acaricides were tested for control of broad mite populations in a 15-year-old commercial lemon grove (120 trees per acre) in Oxnard, Calif. Treatments were applied 27 July to 6 by 6 tree plots, using a Hardie hand-gun at 450 lb/in2 and approximately 1,000 gal/acre. Larger plots were treated 29 July with an AgTec 6013-5 speed sprayer (double head) at 100 gal/acre. The trees were sampled on each sample date by picking four small fruits (less than 1.5 in. diam.) from each of 16 trees in each plot and examining one field’s width of a 14X hand lens down the interior facing side of the fruit parallel to the stem for all motile life stages.
