| 凯素灵是新近生产的杀虫剂,对卫生害虫有极强的杀灭作用。以此药配成0.30%、0.25%、0.20%和0.15%四种浓度的石膏药笔,作杀灭美洲大蠊试验,其杀灭率分别为100%、95.0%、60.0%、10.0%。新配制的和放置1、4、7、10个月的0.25%浓度药笔,杀灭率分别为95.0%、90.0%、85.0%、65.0%、40.0%。现场初步观察,对卫生害虫灭效良好。认为0.25%和0.30%浓度石膏药笔,可连续使用4个月以上。药笔具有高效、低毒、价廉、使用方便等优点,可以推广使用。 |
| 英文摘要: |
| K-Othrin is a new insecticide which is very effective agaist insects harmful to human beings. When it is mixed with plaster-medicated chalk a concentration of 0.30% was 100% effective in killing Periplaneat americana, of 0.25%~95.0%, of 0.20%~60.0% and of 0.15% was 10.0% effective. Effectiveness was reduced through time, so that the 0.25% medicated chalk can kill 95% insects when they are newly produced, 90% after 1 month, 85% after 4 monthes, 65% after 7 monthes and 40% after 10 monthes respectively. According to the field observation, the effect of the medicated chalk in killing insects is excellent. It is suggested that the 0.25% and 0.30% medicated chalk could be used continuously for at least 4 monthes. The medicated chalk could be used widely as they are more effective, less toxic, cheaper and more convenient. |
