【目的】研究18.6%拌.福.乙(18.6%拌种灵.福美双.乙酰甲胺磷)悬浮种衣剂对大型氵蚤、斜生栅列藻和蚯蚓的毒性及其安全性。【方法】通过接触、经口及试验毒性测定。【结果】18.6%拌福乙悬浮种衣剂对水氵蚤48 h-EC50值为0.168 mg/L,斜生栅列藻72 h-EC50值为9.12 mg/L,对蚯蚓的14 d-LC50值大于101mg/kg干土。18.6%拌福乙悬浮种衣剂无闪点,对包装材料无腐蚀性。【结论】18.6%拌福乙悬浮种衣剂对大型氵蚤为高毒级,对斜生栅列藻和蚯蚓为低毒级,在运输和存放过程中不存在任何危险。
【Objective】 The purpose of this study was to investigate the toxicity and safety of 18.6% Bifidobacterium bifidum B (18.6% seed dressing, thiram and acephate) to the large scale fleas, 【Method】 By contact, oral and test toxicity. 【Result】 The results showed that the 48 h-EC50 value of 18.6% bifonic-2-suspended seed coating was 0.168 mg / L, the 72 h-EC50 of Phasianus albus was 9.12 mg / L, Values greater than 101 mg / kg dry soil. 18.6% mixed with b suspended seed coating no flash point, non-corrosive to the packaging material. 【Conclusion】 18.6% of bFGF suspensions are highly toxic to large flea fleas and have low toxicity levels to Paraxalia obliquus and earthworms. There is no danger during transport and storage.
