1 billion/gram high-resistance benzimidazole germicide trichoderma conidium wettable powder and preparation method thereof

Abstract

The invention relates to 1 billion / gram high-resistance benzimidazole germicide trichoderma conidium wettable powder and a preparation method thereof, belonging to the technical field of biopesticides. The 1 billion / gram trichoderma conidium wettable powder comprises the following components: trichoderma conidium, a wetting agent DY-ETE301, sodium lignin sulfonate used as a dispersing agent, riboflavin used as an ultraviolet protective agent, residual rice powder, diatomite, and the like. In the method, a separating type processing technology is used for processing and preparing the wettable powder. The wettable powder can be applied to preventing and treating plant diseases such as gray molds, rhizoctonia rot, damping off, droops, and the like of various field crops and vegetables together with benzimidazole germicides. The prevention and treatment ratio of the wettable powder is higher than 80 percent, and the wettable powder has no environmental pollution, no harm to humans and animals and convenient use; and the quality guarantee period of the wettable powder is one year, and the spore germination ratio is higher than 80 percent. Meanwhile, the wettable powder has the characteristics of long efficacy duration, obvious yield increasing effect, small application amount, little chemical pesticide residue, effective environmental pollution reduction, and the like.

Description

technical field [0001] The invention belongs to the technical field of microbial pesticides, in particular to the preparation of highly resistant benzimidazole fungicide microbial spore powder wettable powder. Background technique [0002] Trichoderma grows fast, produces large spores, and inhibits a variety of plant pathogens. However, it is sensitive to benzimidazole fungicides and cannot play a biological control role when these fungicides are applied in the field. At present, the use of biocontrol factors alone to control crop diseases is often disturbed by environmental conditions and other factors, resulting in unstable control effects in the field. Due to the long-standing problem of sensitivity to chemical pesticides, they cannot be used simultaneously with chemical pesticides. Integrated management of plant diseases. Therefore, in order to solve the problems faced in the application of biocontrol bacteria, realize the combined use of chemical pesticides and Trichod...
