集装箱卫生处理复配药剂效果的研究

Study on the Effect of Drug Combination for Sanitary Treatment of Containers

目的 :观察两种不同药剂复配 ,对现用集装箱卫生处理的效果。方法 :模拟现场试验。结果 :硫酰氟、溴甲烷和虫菌畏单一使用 ,在常用浓度下对大肠杆菌灭菌率在 2 5 %以下 ,对淡色库蚊 2 4h杀灭率在 30 .13%以下 ;常用浓度加倍量对淡色库蚊 2 4h杀灭率在 5 5 .2 0 %以下 ;对德国小蠊和美洲大蠊的杀灭率亦仅为 39.17%和 43.33%以下。溴甲烷、环氧乙烷、硫酰氟中两种药剂复配使用药效提高明显 ,其中硫酰氟与环氧乙烷或溴甲烷与环氧乙烷复配使用 ,杀虫、灭鼠效果尤好。结论 :本文首次报道硫酰氟与环氧乙烷复配使用可明显提高药效。

Based on the investigation of Practical effect of available insecticides used for sanitary treatment of containers,the effect of a combination of two insecticides was observed to see whowed that when Sulfury fluoride, Methy1 bromide and Chong-Jun-Wei were applied separately at routine concentration,their killing rates were<25% for Escherichia coli, < 30.13 % for Culex pipiens pallens in 24 hours; and < 55.20 % for Culex pipiens pallens when the dosage was doubled; and it was only 39.17 % and < 43.33 % respectively for Blattella germanica and Periplaneta americana .However,when Sulfury fluride, Methy1 bromide and Chong-Jun-Wei were used in two drug combination separately, their insecticidal effect could be raised obviously.The best combinations were Sulfury fluoride with Ethylene oxide,and Methy1 bromide with Ethylene oxide,which have good killing effect against insects and rats. This is the first report on Sulfury fluoride and Ethylene oxide combination.
