青虫菌是一种细菌杀虫剂,它对多种害虫具有强烈的毒杀能力。我们微生物农药厂在广大贫下中农协助下,用自己试制成功的青虫菌,在十个公社二十五个大队进行了防治棉铃虫(二代)效果试验。现将试验结果,总结如下: 一、青虫菌防治棉铃虫效果显著为了观察青虫菌对棉铃虫的毒杀能力,并与其他化学农药进行比较,确定其在生产上的应用价值,我们在多点进行了青虫菌防治棉铃虫效果试验。试验共分四个处理,每处理最小
Coccidian is a bacterial pesticide, which has a strong ability to kill a variety of pests. With the assistance of the poor and the middle-income peasants, our microbial pesticide factory carried out the efficacy test of controlling cotton bollworm (second generation) in the 25 brigades of the 10 communes with its own trial-produced caterpillar fungus. Now the test results are summarized as follows: First, the prevention and treatment of Helicoverpa armigera significant effect of bollworm In order to observe the toxicity of Helicoverpa armigera on cotton bollworm, and compared with other chemical pesticides to determine its value in the production, we at more points Helicoverpa armigera control effect of cotton bollworm effect test. The experiment is divided into four processing, each processing the smallest
