Acremonium hansfordii Ahy1 and Acremonium hansfordii wettable powder

Abstract

The invention discloses Acremonium hansfordii Ahy1 and Acremonium hansfordii wettable powder. The Acremonium hansfordii wettable powder comprises the following components in percentage by weight: 10 percent of Acremonium hansfordii conidium powder, 2 percent of wetting agent, 5 percent of dispersing agent, 0.8 percent of ultraviolet protective agent, 1 percent of stabilizing agent and the balance of carrier. The Acremonium hansfordii Ahy1 is screened and separated in a drought environment, is different from strains from other areas due to the geographic environment in which the Acremonium hansfordii Ahy1 is positioned, and has good property of high stress resistance. Meanwhile, indoor and field efficacy proves that the Acremonium hansfordii wettable powder has high infectivity on aphid.

Description

technical field [0001] The invention relates to the field of microorganisms, in particular to a fungus Acremonium acremonium strain and acremonium wettable powder. Background technique [0002] Due to the serious impact on the environment and ecology caused by the extensive use of chemical pesticides, people pay more and more attention to biological control, and the use of entomopathogenic microorganisms to control pests is one of the important biological control methods. Among entomopathogenic microorganisms, insect fungal diseases occupy an important position and play a very important role in the biological control of pests. For example, my country uses Beauveria bassiana to treat the soil, reducing the population of beetle larvae in the peanut field by more than 50%, up to 86.6%. As a kind of valuable biological resources, entomopathogenic fungi have attracted great attention of biologists. Beauveria bassiana is the most researched and applied in various countries now, ...

[0005] In addition, the development of Entomomycetes fungal preparations is also a hot spot in the study of Entomycetes in recent years. Although the new methods reported in recent years have considered the biological characteristics of Entomycetes in process design, the process is difficult and costly, and the subsequent drying and Preservation is more difficult. For example, although seaweed salt has many advantages as an embedding matrix, it has poor water retention, easy leakage of additives, easy dehydration and drying, which is not conducive to rehydration and germination of spores of strains, poor mechanical strength and glue ball adhesion. and other defects
