The test was conducted in a 2-yr-old orchard of ‘Redchief’ apples. Replicate blocks were based on a pretreatment population count of European red mite. Treatments were applied with a handgun to the point of drip on 16 Aug. Samples consisted of 5 leaves/tree picked at random throughout the canopy. The leaf samples were kept cool until brushed with a mite-brushing machine. Samples were taken ca. weekly after treatment until phytophagous mite populations were too low to warrant further counts.
