The degradation of some organophosphorus insecticides by phosphatases was studied in water, soil, and soil extract. There is an obvious effect of the phosphatases in solution, but no effect of the enzymes was noted on the insecticides which were adsorbed on the soil surface, even after multiple enzyme applications.
