Abstract

The invention discloses bacillus for preventing and treating root rot of paris polyphylla, and a preparation method and application thereof. A paenibacillus polymyxa strain HJ-2 is adopted to infect the fusarium zoospores, then germination of fusarium spore is further inhibited, and harm of fusarium to rhizome parts of the paris polyphylla is reduced, so that harm of root rot to the paris polyphylla is reduced, the yield of the paris polyphylla is ensured, and economic loss of pesticide farmers is reduced. In addition, the paenibacillus polymyxa strain HJ-2 is used for biological prevention, so that pesticide residues are not generated, and the bacillus provided by the invention has the characteristics of greenness and recyclability, good prevention and control effect, avoidance of pesticide residue pollution and the like.
