Apple, European Red Mite and Apple Rust Mite Suppression, 1976
Insecticide and Acaricide Tests, 1977Abstract Three application rates of each of three pesticides were evaluated for suppression of mite populations in a block of six year old apple trees on M M 106 rootstock at Massies Mill , VA. The rows were laid out in an east-west direction with 22 feet between them. Tree spacing in the row was 12 feet.

The European Red Mite, Paratetranychus Pilosus
Journal of Economic Entomology, 1928Early season development of red mite is reported as profuse on lime sulfur sprayed plots and meager on oil sprayed plots. By the end of the season the conditions were reversed, having been brought about in large measure through the biological control effected by the lady beetle, Slelhorus punctum Lec.

Control of European Red Mite and Peach Silver Mite, 1978
Insecticide and Acaricide Tests, 1979Abstract A 10- to 15-year-old mixed variety block of peaches was selected for this test. An early application of Pydrin was used to remove predators. All plots were sprayed to the point of drip with hand guns at 400 to 500 psi. Plots consisted of four single-tree replicates randomized throughout the block.

Control of Mcdaniel Spider Mite and European Red Mite, 1979
Insecticide and Acaricide Tests, 1980Abstract A 10 year old block of Italian prunes was selected for this test. An early application of 3 oz/100 gal of Pydrin 2.4EC was used to eliminate predatory mites. A completely random design with 5 single tree replicates per treatment was used in this test.

Preharvest Control of European Red Mite, 1990
Insecticide and Acaricide Tests, 1991Abstract Mature commercial pear trees in the Sacramento River delta were treated with aearicides using a hand-held orchard sprayer operating at 200 psi and delivering 400 gal/acre of finished spray. Trees were arranged in a randomized complete block design with 7 treatments replicated 4 times.
