Pesticide usage patterns were studied in 18 and 19 commercial apple orchards in Ohio during 1979 and 1980, respectively. Conventional every-row spraying was used in almost every orchard during the 2-year period. Phosmet and azinphosmethy1 were the predominant insecticides utilized, whereas captan, Dikar, and benomyl were the most frequent used fungicides. Superior oil applied in early spring and cyhexatin were the most common materials for control of mites. Insecticides and fungicides were applied at nearly half the Ohio recommended full dilute rates. Average expenditures for insecticides in 1979 were $107/haand $115/ha in 1980. Looses from principal insect pests, redbanded leafroller, Argyrotaenia velutinana (Walker), and plum curculio, Conotrachelus nenuphar (Herbst), were less than 2% annually.
