Mite Control, 1979

Experimental miticides were evaluated for efficacy against citrus rust mite (CRM) in randomized block designs. Treatments were replicated 5 times in tests 1 and 2 (Tables 1 and 2) and 4 times in test 3 (Table 3). An unsprayed buffer tree separated treated trees both within and between rows. Sprays were applied dilute with a handgun at 400 psi using a truck-mounted sprayer. Approximately 20 gallons (test 1) and 5 gallons (test 2 and 3) of finished spray were applied to each sample tree which equalled ca. 1400 and 455 gallons per acre, respectively. Twenty fruit were examined at random around the canopy of each sample tree at various time intervals before and after spraying. A 1 cm area was examined on each of 2 shaded sides per fruit. The combined 2 cm count of motile CRM was recorded as one observation.
