“424”(苏云金杆菌)是一种良好的病菌杀虫剂。菌粉外观为灰白色至浅黄色的疏松粉末(长沙微生物制品研究所产品)或褐色颗粒状,具麦麸发酵味,经试验能防治多种害虫。从1967年开始,我们用“424”对松毛虫进行了多次防治试验,取得了显著效果。1971年我们采用衡阳回雁峰酒厂土法生产的“424”,在安仁县军山公社芙壙大队防治第一代松毛虫,效果同样良好。实践已证实,它是今后防治松毛虫较有前途的一种新菌剂。现在我省与我地区均开始生产,以进一步满足防治上的需要。为了今后在我地区结合白殭菌推广使用,现将有关方法加以整理介绍如下,以供各地防治参考。
“424” (Bacillus thuringiensis) is a good germ-killing pesticide. Bacterial powder appearance is gray to light yellow loose powder (Changsha Institute of Microbial Products) or brown granular, with wheat bran fermentation, the test can prevent a variety of pests. Since 1967, we used “424” to control pine caterpillars for many times and achieved remarkable results. In 1971, we adopted the “424” produced by the indigenous company of Hengyang Hui Yanfeng Winery, and the first generation of the pine caterpillars was also prevented and controlled in the Fuyou Brigade of the Jun Hill Commune in Anren County, and the effect was equally good. Practice has confirmed that it is a new fungicide for the future prevention and control of pine caterpillars. Now our province and my region are beginning to produce, in order to further meet the needs of prevention and treatment. In order to promote the use of Beauveria in my area in the future, the related methods are summarized as follows for reference.
