Beauveria bassiana granular formulation and preparation method thereof

Abstract

The invention relates to a white muscardine fungus granular formulation and a preparation method thereof. The white muscardine fungus granular formulation is prepared by the following compositions in mass percentage: 1 to 20 percent of white muscardine fungus spore powder, 70 to 95 percent of carrier, 0.05 to 3 percent of an adhesive, 0.5 to 5 percent of a disintegrant, 0 to 2 percent of a disintegration assistant, 0.01 to 1 percent of a dispersant, 0.5 to 5 percent of an anti-ultraviolet agent, 0 to 3 percent of a lubricating agent, and 0 to 2 percent of a coloring agent. The preparation of the white muscardine fungus granular formulation can adopt an extrusion molding granulation method, a fluidized bed granulation method and a coating granulation method. The white muscardine fungus granular formulation has the obvious characteristics that the storage period of white muscardine fungi is between 10 and 12 months, and the white muscardine fungus granular formulation can be directionally and accurately applied, is particularly applicable to killing underground pests, is convenient to pack, store, transport and use, does not pollute the environment, and can also control the release rate of the white muscardine fungi and prolong the lasting period.

Description

technical field

[0001] The invention relates to a fungal insecticide preparation, specifically a Beauveria bassiana granule and its preparation method. Background technique

[0002] With a series of serious problems caused by the extensive use of chemical pesticides, such as polluting the environment, destroying the ecological balance, and developing resistance of pests, biological control has attracted more and more attention. Beauveria bassiana is an important entomopathogenic fungus, which has the advantages of strong pathogenicity, wide insecticidal spectrum, no toxicity to humans, animals, forestry crops, and no pollution to the environment. Therefore, in recent decades, Beauveria bassiana has been used as a potential Huge biopesticides are subject to extensive and in-depth research at home and abroad.

[0003] In the early days, the dosage form of Beauveria bassiana insecticides in my country was mainly powder, which contained a large amount of fillers, culture medium...
