Abstract
Methomyl, endosulfan, demeton, and chlordimeform hydrochloride were highly toxic to adult Phyllonorycter crataegella Clemens in laboratory tests. Endosulfan and endosulfan + pyrethrin also were effective in field treatments applied during moth flight. Methomyl and oxamyl were the most effective insecticides screened for control of the larvae. Because of the present inability to predict the necessity or effectiveness of prophylactic spring brood or 1st brood moth sprays, it is suggested that growers assess the severity of 1st and 2nd brood larval infestations before applying control measures.Keywords
