杀螨杀虫剂米尔贝霉素的风险评估

Risk Assessment of the Insecticide/Acaricide Milbemectin

根据挪威食品安全委员会对米尔贝霉素的风险评估报告,在果树上喷洒米尔贝霉素对操作人员有一定的风险,需要防护装备,而对草莓及观赏作物喷洒时对操作人员和农业操作者无风险。米尔贝霉素对哺乳动物、鸟类无影响,对蜜蜂存在风险。当作物喷洒2次米尔贝霉素时,在土壤中的残留对节肢动物中野生食肉动物和拟寄生物有较高风险,对蚯蚓存在中等的风险。在果树喷洒推荐剂量的米尔贝霉素对30 m范围内地表水的水生生物存在中等的毒性风险,而对草莓及观赏作物喷洒米尔贝霉素不会对水生生物产生风险。

According to the report of risk assessment of milbemycin from Norwegian scientific committee for food safety, there is certain risk to operators when applying milbemycin to fruit trees, with the result that it needs protection equipment. But there is no risk when applying milbemycin to strawberries and ornamental crops. Milbemycin doesn＇t effect mammals or birds, but does for bees. The residual of milbemycin in the soil poses high risk to foliage dwelling predators and predatory mites, and medium risk to earthworm when it is applied twice on crops. There is medium risk to aquatic life living in the water within thirty meters from the surface of the earth when applying milbemycin of applicable dosage to fruit trees, but no risk to aquatic life when applying milbemycin to strawberries and omamental crops.
