摘要
[方法]采用经口半致死毒性测定方法研究18.6%拌·福·乙酰甲悬浮种衣剂对鹌鹑、家蚕、蜜蜂、斑马鱼4种生物的急性毒性,并对其进行环境安全性评价。[结果]18.6%拌·福·乙酰甲悬浮种衣剂对鹌鹑7 d的LD50值为314(雄性)、278 mg/kg(雌性),对家蚕96 h的LD50值为40.2 mg/L,对蜜蜂48 h的LD50值为4.74 mg/L,对斑马鱼96 h的LD50值为0.783 mg/L。[结论]18.6%拌·福·乙酰甲悬浮种衣剂对鹌鹑和家蚕为中毒级。对蜜蜂为高毒级,但该药剂主要用于种子包衣,且包衣种子播种至开花期相隔时间较长,因此对蜜蜂的风险极小。对斑马鱼为高毒级,应严格避免药液流入水域对鱼类造成危害。
[Methods] The LD50 of acute toxicity test was carried out in the experiments.The acute toxicity and environmental safety evaluation assay was researched on quails,silkworms,bees and zebrafishes against amicarthiazol·thiram·acephate 18.6% suspension seed coating.[Results] The result showed that the LD50 value was 314 mg/kg(male) and 278 mg/kg(female) against quails at the treatment time of 7 d,was 40.2 mg/L against silkworms at the treatment time of 96 h,was 4.74 mg/L against bees at the treatment time of 48 h,was 0.783 mg/L against zebrafishes at the treatment time of 96 h.[Conclusions] The results indicated that amicarthiazol·thiram·acephate 18.6% suspension seed coating was moderate toxicity to quails and silkworms.It was highly toxicity to bees and zebrafishes.But amicarthiazol·thiram·acephate 18.6% suspension seed coating was usually used for be coated and there was very long time from sow the seeds in the ground to blossom,therefore it was safety to bees.Moreover,it was highly toxicity to zebrafishes,when amicarthiazol·thiram·acephate 18.6% suspension seed coating was used in fields,it should be avoided strictly the pesticide liquid pouring into river.
