Apple, Summer Mite Control, 1975

Acaricide treatments were applied midseason to young apple trees. The trees had a grower applied, standard spray schedule until mid-July. On July 24 a spray of Captan 50W 4 lb + Sevin 50W 4 lb/A was uniformly applied at 4X concentration (100 gal/A). The acaricides were applied July 31 with a high pressure hydraulic sprayer operating at 540 psi. The trees were sprayed to run off. Dual tree treatments were replicated 5 times. The mite populations were sampled the day of treatment and at weekly intervals for the following five weeks.
