Wettable powder for fungi spore

Abstract

The invention provides a fungus spore wettable powder which comprises diatomite 85-90%, lignin 1-30%, carboxymethyl cellulose 0.1-1%, sodium humate 0.01-0.2% and Gliocladium spp. spores powders having hyperparasitism actions against various plant pathogenic bacteria such as sclerotiorum, gray mold bacterium, sheath blight bacterium and root rot bacterium.

Description

Technical field: [0001] The invention relates to the technical field of microorganisms, in particular to a fungal spore wettable powder. Background technique: [0002] Compared with chemical pesticides, the formulation processing of live microbial pesticides is more difficult. First of all, microorganisms are water-insoluble organisms, and the hydrophobicity of their particles directly affects the physical properties of preparations such as wettability, dispersibility, and suspension. Secondly, as organisms, microorganisms are sensitive to external environmental factors such as temperature, humidity, and light, and the storage stability of the preparation is poor, the action speed is slow, and the field duration is short; therefore, the physical and chemical properties of the preparation should be considered when selecting an adjuvant. In addition, some special additives, such as anti-light agents and synergists, should also be considered. Furthermore, as living organisms,...

Problems solved by technology

[0003] Among living microbial pesticides, fungal spores can be made into powder, granule or wettable powder, etc., but powders are generally used in dusters and cannot be sprayed with water. They are required to be used under windless conditions, which has the disadvantage of drifting and polluting the environment; granules The agent is the product dosage form used in the soil, and it is used by manual spreading or soil mixing, and the general dosage is large
