复方熏蒸剂杀菌杀虫效果研究

目的了解硫酰氟与环氧乙烷、右旋苯氰菊酯复方熏蒸剂替代溴甲烷熏蒸的杀菌杀虫效果。方法杀菌参考《消毒技术规范》2002版2.1.3.4,做实验室试验和模拟现场试验。杀虫参考《农药登记用卫生杀虫剂室内药效试验方法》GB13917.3-1992,做室内药效试验和模拟现场试验。结果 硫酰氟与环氧乙烷、右旋苯氰菊酯复方熏蒸剂按100 g/m3加入1 m3气雾柜,作用9 h,对大肠杆菌和金黄色等等球菌的杀灭率均为100%。该熏蒸剂按100 g/m3加入20 m3气雾室内作用24 h,对大肠杆菌和金黄色葡萄球菌的杀灭率也均为100%。该熏蒸剂按55 g/m3加入玻璃方箱,作用30 min对致倦库蚊、家蝇、德国小蠊、黑皮蠹等害虫的24 h死亡率为100%。该熏蒸剂按55 g/m3加入28 m3模拟现场,作用30 min对致倦库蚊、家蝇、德国小蠊、黑皮蠹等害虫的24 h死亡率为100%。结论硫酰氟与环氧乙烷、右旋苯氰菊酯复方熏蒸剂对大肠杆菌、金黄色葡萄球菌和致倦库蚊、家蝇、德国小蠊、黑皮蠹等有较好杀菌杀虫效果。该熏蒸剂可以替代溴甲烷熏蒸剂对集装箱等物品进行熏蒸,能取得良好的杀菌杀虫效果。
