The results showed that from the 3rd to the 5th day after spraying, phorate and emamectin benzoate residues in Jinpin 70 with ball well protected reduced by 76.47%-87.65% and 67.86%-80.82% re- spectively compared with Xubao, and decreased by 9.23%-81.82% and 57.14%- 79.84% respectively compared with Jinpin 70 with ball unprotected. The results above demonstrates that inner leaves of cauliflower with ball well protected can prevent the ball from being polluted by phorate and emamectin benzoate, thereby improving its edible safety.展开更多
