我们在氯硝柳胺乙醇胺盐可湿性粉剂室内浸杀和现场喷杀的基础上,进行了室内喷杀和室外浸杀灭螺试验,结果如下。 1 方法 1.1 室内喷杀 取大小为28×18cm的瓷盘4个,盘底垫上草纸,用去氯水湿润,然后在每盘中均匀投入100只钉螺,饲养1d后,在各盘中分别均匀地喷洒浓度为1g/m~2、1.5g/m~2、2.0g/m~2的氯硝柳胺乙醇胺盐可湿性粉剂,另一盘清水饲养作为对照。于喷洒后3d、5d、7d,分别在每盘中抽取钉螺25只,洗净,饲养1d后,再用敲击法鉴定死活。
We nicotine ethanolamine salt wet indoor powder immersion and spray on the basis of the indoor spray kill and outdoor dip snail test, the results are as follows. 1 Method 1.1 indoor spray to take the size of 28 × 18cm porcelain dish 4, the tray bottom pad of turf, moistened with chlorine water, and then evenly put in each 100 snails, feeding 1d, respectively, in each plate evenly The niclosamide ethanolamine salt wettable powder was sprayed at a concentration of 1 g / m ~ 2, 1.5 g / m ~ 2, and 2.0 g / m ~ 2, and the other was kept as a control. On the 3rd, 5th, 7th day after spraying, 25 snails were collected in each dish respectively, washed and kept for 1 day, and then the percussion method was used to determine the life and death.
