Tóm tắt

In order to better understand the environmental impact of systemic pesticides used in the seed treatment, we conducted a field trial by planting maize seeds treated with thiamethoxam (TMX) and the combination with difenoconazole (DFZ), two of the commonly used systemic pesticides in the seed treatment program. We found most of pesticide residues were retained in the 0-10 cm layer from soil surface. Pesticide residue levels exhibited a significant decreasing trend from the seedling to milk period. The highest level of TMX in the profile soil were 0.068 and 0.036 μg·g
