Abstract:
The mobility of nano-formulated chlorpyrifos was analyzed in sandy loam soil, under laboratory conditions. During this analysis, nano-formulated chlorpyrifos mobility was contrasted with conventional chlorpyrifos. The leachates and soil samples at different depths of soil column were monitored over the time. The residues of chlorpyrifos in leachates and soil were estimated by high pressure liquid chromatography (HPLC). The results indicated a noticeable decrease in the mobility of nano-formulated chlorpyrifos compared to the conventional form, where the nano-formulated chlorpyrifos was detected only up to 10-15 cm of depth while the conventional chlorpyrifos was detected up to the depth of 25-30 cm. This result emphasizes the potential advantages of nano-formulations in reducing the spread of pesticides outside the intended areas.
