利用喷烟机使用2%阿维菌素油烟剂和4.5%高效氯氰菊酯乳油进行了防治杨树食叶害虫的防治成本、效果及污染情况对比试验。试验结果表明,2种烟雾剂的杀虫效果都很好,害虫死亡率均达95%以上,但防治成本前者比后者低得多。但是,前者对人畜有较高的毒性,杀伤天敌,对环境产生污染,而后者属于抗生素类杀虫杀螨剂,对害虫具有胃毒和触杀作用,对环境无污染,不杀伤天敌,防治效果好。
The use of 2% abamectin puff smoke machine and 4.5% beta-cypermethrin EC were used to control poplar leaf pest control costs, effects and pollution comparison test. The test results show that the two aerosol insecticidal effect is good, the pest mortality rate reached more than 95%, but the prevention and control costs are much lower than the former. However, the former has higher toxicity to humans and animals and kills natural enemies and pollutes the environment, while the latter belongs to the antibiotic insecticide and acaricide, which has stomach poisoning and contact toxicity to the pests, has no environmental pollution and does not kill natural enemies, and has the effect of controlling it is good.
