The invention discloses a microbial pesticide preparation for plant protection and growth adjustment, which comprises 0.5 to 5 percent of Wuyi-bacterium spore powder, 5 to 25 percent of choline chloride, 10 to 30 percent of light rare earth, 5 to 20 percent of methionine, 1 to 8 percent of zinc sulfate, 0.3 to 3 percent of cupric sulfate, 1 to 5 percent of boric acid, 0.05 to 0.5 percent of vitamin B, 0.05 to 0.5 percent of vitamin C, and filler kaolin allowance. The invention has the advantages as follows: Wuyi biocontrol bacterium spores are taken as a main body, and meanwhile organic acidssuch as salicylic acid without phytotoxicity, and other components facilitating the plant degeneration resistance and growth promotion, such as choline chloride, trimethyl glycine, light tombarthite,amino acid and the like are matched up, the microbial pesticide preparation for plant protection and growth adjustment has obvious disease preventing, disease resisting, and degeneration resisting effects, improves crop yield, enhances the quality of crop production, has an obvious yield-increasing effect, can keep the yield to be improved by more than 10 to 15 percent, has a durable effect, is stable in resisting effect, low in cost and simple in processing technique, and has no pollution from waste material.
