Abstract
A mite, Oligonychus pratensis (Banks), has been causing concera Among wheat growers in western Kansas during recent Years. Heavily infested plants have been killed by a combination of mite feeding and insufficient soil moisture. In 1958 demeton, Trithion,® parathion, Kelthane,® Guthion,® Tedion® and malathion reduced mite populations significantly 3 days after application but none provided satisfactory control and none was effective 14 days after treatment. In 1959, all materials reduced mite populations 4 days after application but only Trithion, Kelthane, and parathion provided high initial mortality. Demeton gave fair control but Phostex® and Delnav® were ineffective, Trithion and Kelthane were superior to all other materials 14 days after treatment. Parathion applied at 1.0 lb. per acre by airplane significantly reduced mite populations and gave a substantial increase in seed yield. Definitions of chemicals bearing proprietary names above are as follows: Delnav (2,3-p-dioxanedithiol S,S-bis(O,O-diethyl phosphorodithioate 68%-70% and related materials)). Guthion (O,O-dimethyl S-( 4-oxo-1, 2,3-benzotriazin-3-( 4H)-ylmethyl) phosphorodithioate). Kelthane (4,4’-dichloro-alpha-(trichlorometllyl)-benzhydrol). Phostex (a mixture of bis(dialkyloxyphosphinothioyl) disulfides). Tedion (2,4,4’,5-tetrachlorodiphcnyl sulfone). Trithion (S-(p-chlorophenylthio)methyl O,O-diethyl phosphorodithioate).
