Abstract

In order to explore new ways and methods for the degradation of organophosphorus pesticides, the degradation effects of plant-derived active ingredients on three organophosphorus pesticides were studied. Rhubarb, Pittosporum bark, Hibiscus bark, and Chinese gall in 9:4:3:2 parts were mixed by mass, ground and soaked in water, and the concentration changes of organic phosphorus pesticide before and after the test were compared through GC-MS quantitative detection method and rapid pesticide residue measurement method to clarify its degradation effect on organophosphorus pesticides. The results showed that the degradation rates of chlorpyrifos and parathion were 93.2% and 92.9% respectively in the extract within 2 minutes; the degradation rate of dichlorvos was 66.67% in the extract within 17 hours, and the degradation rate of chlorpyrifos was 48.69% within 11 hours. This study shows that the extracts of rhubarb, sea tongs bark, hibiscus bark, and gallnut have significant degradation effects on chlorpyrifos, parathion, dichlorvos and other organophosphorus pesticides.
