Luoyang News reporter learned from the Municipal Forestry Bureau yesterday that the city’s first use of biological control of forest pests and diseases has been successful. According to briefings, recently, the forestry department used Bacillus thuringiensis powder to biologically control poplar pests and diseases planted on the aisles in the territory of Zichuan County, covering an area of ​​500 mu. From the results of the verification, the control effect reached 90%, effectively preventing the spread of pests and protecting the natural enemies of pests. Bacillus thuringiensis belongs to the class of Bacterial Insecticides. It is non-toxic to humans and animals, has no phytotoxicity to crops, and is safe to natural enemies of pests. After it acts on insects, it can paralyze the intestinal tract within a few minutes, causing insects to stop feeding and causing their death. It is reported that in the past, the city mainly used chemical pesticides to prevent forest diseases and insect pests, which not only made it easy to cause environmental pollution, but also killed natural enemies of pests.
