Concern about persistence of synthetic pesticides in soil and the environment in general has been greater where chlorinated hydrocarbon compounds have been involved than where organophosphorus pesticides have been used. The experiment involved treatments of field soil plots using three liquid parathion concentrations and two different formulations. Treatments were: (a) Undiluted commercial grade 45.6% liquid emulsifiable concentrate; (b) conventional dilute spray for orchard use prepared from water-wettable powder and containing 0.03% parathion (referred to as 1X concentration); (c) a dilute spray similar to (b) except prepared from emulsifiable concentrate; (d) a spray micture of the type commonly used for semi-concentrate spray applications prepared from water-wettable powder and containing 0.24% parathion; and (e) a spray mixture similar to (d) except prepared from emulsifiable concentrate.
