Infested dormant azaleas, growing in trade gallon (3-liter) black plastic containers of an amended pine bark medium, were selected for a single foliar-applied treatment. Chevron spray sticker (0.5 pt/100 gal water) was added to all chemical treatments. Sprays were applied to all leaf surfaces to run-off with an R&D CO2-pressurized test pilot sprayer (35 psi) equipped with a single Spray Systems cone-jet T nozzle. Four single-plant replicates were arranged in a completely randomized design and held in an open, unheated glass greenhouse. Live mites were counted at 7, 21, 35, and 63 DAT with the aid of a Llanfair Orchard leaf-brushing machine and a microscope. Each sample consisted of 3 randomly selected 6-cm terminals/plant. Terminals were clipped and brushed, and the number of mites landing on the counting disk was recorded.

Test plants were ca. 1 ft tall, growing in 3-qt plastic pots filled with an amended pine bark medium. Fourteen insecticides were applied by 1 or 2 methods: foliar sprays or insertion of fertilizer spikes impregnated with an insecticide into soil around plant. Treatments were replicated 4 times, one plant constituting a replication. A single application of the test materials was made out-of-doors on 17 Jun (Dry Bulb 86°F: Wet Bulb 78°F). The adjuvant Nu-Film 17 was added to all spray mixtures at the rate of 2.4 ml/gal. Foliar sprays were applied to runoff using a hand-pumped compressed air sprayer and spikes were placed ½ inch below soil surface, 1 inch from pot rim, and watered in. Test plants were returned to a screened shadehouse. Efficacy was determined 1 Jul by examining 100 citrus whitefly pupae per plant and scoring them as dead or alive.

Infested variegated liriope growing in 1-gal containers of an amended pine bark medium were selected for the foliar treatments listed. Miticides plus Chevron Spray Sticker (0.5 pt/100 gal water) were applied to all leaf surfaces to run-off with a hand-pumped, compressed air sprayer. Four single-plant replicates were arranged in a completely randomized design. Live mites were counted 7 and 21 days after treatment with the aid of a Llanfair Orchard Leaf Brushing Machine and microscope. Each sample consisted of 3 randomly selected mature leaves per plant.

Thirty-two 1-yr-old azaleas growing in 1-gal plastic pots were selected for treatment. Test materials were applied 11 Sep with hand-held compressed air sprayers. Chevron spray sticker was added to all treatments at a rate of 2.4 ml/gal spray mixture. There were 4 single plant replicates arranged in a completely randomized design. Treatments were evaluated 7 and 21 DAT by brushing 5, 6 cm terminals from the lower canopy of each plant utilizing a mite brushing machine and recording the number of living mites landing on the counting disc.
