| Abstract: | Leaching studies were conducted on endosulfan and methamidophos in two soil types, sandy loam and clay under simulated rainfalls of 10, 50 and 100 mm using soil columns. The results showed that, although methamidophos was more susceptible to leaching than endosulfan,the degree of leaching of both insecticides was distinctly affected by soil types. Leachate of the insecticides collected from the sandy loam soil was found to increase with increasing amount of simulated rainfalls, ranging from 0.002% to 0.12% for endosulfan and 0.019% to 7.59% for methamidophos. Leachate of endosulfan was not found in detectable amounts in the clay soil but that of methamidophos (0.145%) was detected only at 100 mm rainfall simulation. |
