Abstract

To clarify the runoff characteristics of the pesticide applied paddy fields to water environment, detail dynamic behavior of herbicide daimuron was investigated based on daily change for concentration of pesticide in pooled water and soil water. The concentration of daimuron was reached maximum within 24 hr. after application, its concentration was corresponding with the theory value. After reaching the maximum concentration, the concentration was rapidly decreased according as a pseudo first-order rate curve. Also, after rainfall events, daimuron concentration of the pooled water was increased. These results indicated that the sorption and desorption occurred the interface between pooled water and surface soil. The pesticide concentration of soil water was reached maximum concentration at 10-14 days after application. The reaching volume were lesser compared with the surface runoff volume, daimuron has 1/173 ratio. These results showed that daimuron was discharged from paddy field by the surface runoff.
