根据供试化学农药的降解规律以及我国和各国制订的茶叶中允许残留标准,可分为三类:(一)降解速度快,或降解速度虽较慢,但由于对高等动物毒性低,因此安全间隔期仍≤5天——辛硫磷、敌敌畏、二溴磷、二氯苯醚菊酯、溴氰菊酯、放线酮。(二)降解速度中等,安全间隔期6-10天——
According to the degradation laws of pesticides for testing and the allowable residue standards in tea formulated in China and other countries, they can be divided into three categories: (1) The degradation rate is high or the degradation rate is slow, but it is safe because of low toxicity to higher animals Interval is still ≤ 5 days - phoxim, dichlorvos, dibromothiophene, permethrin, deltamethrin, release line ketone. (B) moderate degradation rate, safety interval of 6-10 days -
