Abstract

Degradation characteristics of insecticide diazinon in upland and paddy soils under laboratory conditions were investigated to elucidate the effect of raw pig slurry (RPS) and processed pig slurry (PPS) treatment. Soil (20g) was treated with RPS and PPS by standard rate, double rate and triple rate before treating with diazinon (0.5mg/kg level) and incubating at ($25{\pm}2^{\circ}C$) for 60 days. The half-lives of diazinon in the untreated upland and paddy soil were about 28 and 22 days respectively. The degradation rate of diazinon was faster by $5.0{\pm}1.2$ days in the paddy soil than in the upland soil independent of fertilizer types. This result indicates that soil moisture content affects the half-life of diazinon probably by hydrolysis. Degradation of diazinon was faster in RPS treatment soil than in PPS treatment soil. The more amount of fertilizers were treated, the more rapidly diazinon degraded regardless of fertilizers and soil types. Based on the results obtained, degradation of diazinon in soil was definitely influenced by soil water contents and treatment of those fertilizers.
