ADI/RfD 0.0025 mg/kg. Other Not tumorigenic. Toxicity Class WHO (a.i.) II (company classification).
ECOTOXICOLOGY生态毒理学
emamectin benzoate
Birds Acute oral LD50 for mallard ducks 76, bobwhite quail 264 mg/kg. Dietary LC50 (8 d) for mallard ducks 570, bobwhite quail 1318 ppm. Fish LC50 (96 h) for rainbow trout 174, sheepshead minnows 1430 μg/l. Daphnia LC50(48 h) 0.99 μg/l. Bees Toxic to bees. Worms LC50 >1000 mg/kg dry soil. Other beneficial spp. Safe to a wide range of beneficial insects, due to rapid breakdown of the a.i., limiting contact activity to <48 h.
ENVIRONMENTAL FATE
Animals Emamectin benzoate is partially metabolised but rapidly cleared (DT50 following oral dosing 34–51 h), indicating that it has no potential for bioaccumulation.
甲维盐无潜在生物富集
Plants Metabolism has been investigated in lettuce, cabbage and sweet corn. It is
non-systemic, and rapidly degrades in sunlight to various complex residues in which undegraded parent is the only significant residue. The residues were very low.
甲维盐无内吸作用，光照下迅速分解，植物体中残留低
Soil/Environment Rapidly degraded. 土壤中降解迅速
