Texas Citrus Mite (TCM) and Citrus Red Mite (CRM) Control, 1985

Treatments were assigned to single tree plots in a randomized complete block design and replicated 6 times (test 1) and 5 times (test 2). An unsprayed buffer tree separated treatment trees within and between rows. Materials were applied with a handgun from a truck-mounted sprayer at 200 psi (test 1) and 400 psi (test 2) using ca 2.5 and 5.8 gal/tree respectively. Water pH was 7.5 (test 1) and 7.9 (test 2). Twenty-five leaves from the spring flush were collected around the outer canopy of each treatment tree at various times before and after spraying. The number of living motile spider mites on each leaf was counted by species in the laboratory using a stereomicroscope.
