Abstract
Abstract Thirty-six 1 ft tall, container grown dwarf burford hollies heavily infested with tea scale were selected for treatment. Test plants were growing in 1 gal plastic pots. Test materials were applied Jun 18'79. Chevron spray-sticker was added to all treat-ments at the rate of 2.4 ml/gal of spray mixture. The foliage of all plants was sprayed to runoff using compressed air sprayers. Treatments were replicated 3 times, one plant constituting a replication. Plants were allowed to dry and then were returned to a plastic greenhouse. Efficacy of the treatments was de-termined on Jul 3'79 by examining 100 adult female tea scales per plant. Mortality counts were made with the use of a stereo-microscope by examining each scale insect and scoring it as living if normally colored and fullbodied or dead if discolored and shriveled or dried.
