Degradation of Thiometon in Ethyl Acetate

摘要

When performing multirestidue analysis of pesticides, the recovery of thiometon was less than 20/100 from carrots and eggplants, but about 100/100 from garlic chives and welsh onions. The recovery of thiometon was found to depend on the lot of ethyl acetate. A 2-year-old lot of showed acetate caused degradation of thiometon, but a fresh lot of ethyl acetate did not.
