麦草丹是新型选择性激素除草剂。急性毒性试验结果:麦草丹纯品对雄性大鼠口服LD_(50)为1,710mg/kg,雌性为3,830mg/kg。其胺盐制剂LD_(50)雄性大鼠为650mg/kg,雌性为1,720mg/kg。二者皆属于低毒性农药。麦草丹纯品喂养大鼠3个月亚急性试验,从肝肾功能、脏器系数和病理学检查证明无毒害作用剂量为640ppm。麦草丹的蓄积系数为8.4,表明基本无蓄积作用。据亚急性试验初步推算麦草丹的每日容许摄入量(ADI)为0.64mg/kg。
Wheatgrass is a new selective hormone herbicide. Results of acute toxicity test: The oral LD_(50) of the wheat straw was 1,710 mg/kg for male rats and 3,830 mg/kg for females. Its amine salt formulation LD_(50) was 650 mg/kg for male rats and 1,720 mg/kg for females. Both are low toxicity pesticides. A three-month subacute trial of wheat straw was given to wheat straw for three months. From the liver and kidney function, organ coefficient and pathological examination, the dose of non-toxicity was 640 ppm. The accumulation coefficient of wheat straw was 8.4, indicating that there was basically no accumulation effect. According to the subacute test, the initial allowable intake (ADI) of wheat straw was 0.64 mg/kg.
