Several organophosphate systemic insecticides were field-tested further in 1957, 1958, and 1959 as a control for the Hessian fly, Phyto phaga destructor (Say). The materials used were: Am. Cyanamid 12008 (O,O-diethyl S-(isopropylthio)methyl phosphorodithioate), Di-Syston® (O,O-diethyl S-2-(ethylthio)ethyl phosphorodithioate) and prorate (formerly known as Thimet). These materials were applied with fertilizer from a standard grain-drill at planting time about 1 month before the fly-free date. Seed treatments were also included in some experiments for comparison. One-pound rates of prorate gave excellent protection from Hessian fly attack over long exposure periods. Materials applied with fertilizer significantly increased both forage and grain yields at the 1-pound rate of application.
