Pesticides factors-that increase degradation

Applehans (18) lists several factors that Increase the rate of organophosphate pesticide degradation temperature of 32 C or more, a basic pH, organic compounds In the soil, and activity of microorganisms. Laundering aids or practices that correspond with these factors can be established. 

Any factors that stimulate the growth of soil microorganisms or that increase the availability of pesticides in soil will enhance the degradation of the chemical. Felsot et al. (1981) found that the persistence of carbofuran was inversely correlated with microbial activity in corn-cropped soils. Tu and Miles (1976) reported that 88% of parathion was lost from soil in 7 months diazinon, 92% lost in 20 weeks paraoxon, 100% hydrolyzed in 12 hr mala-thion, 50-90% lost in 24 hr and carbofuran, 50% lost in 3-50 weeks.
