Bacillus wettable powder containing brassinolide and preparation method thereof

Abstract

The invention discloses bacillus wettable powder containing brassinolide and a preparation method thereof. The bacillus wettable powder containing brassinolide is mainly prepared from brassinolide, a bacillus solution, nonyl phenol polyoxyethylene ether, ethanol, skim milk powder, methylcellulose, D425, sodium dodecyl benzene sulfonate and kieselguhr. The brassinolide is capable of improving the activity of plant based enzymes, improving the seed vigor, promoting early development, enhancing the photosynthetic efficiency, increasing the crop yield, improving the crop quality, improving the cold resistance, drought resistance, waterlogging resistance and saline-alkaline tolerance of crops, improving the stress tolerance, and alleviating pesticide phytotoxicity and chemical pollution phytotoxicity, and is capable of resisting hazards of multiple types of virus, bacteria and fungus and enhancing the crop disease resistance. The bacillus is capable of directly restraining or killing multiple types of plant diseases. The wettable powder is safe, environmentally friendly and efficient, is stable in production process, and can be widely applied to crops such as rice, flue-cured tobacco, corn, wheat, stawberries, watermelons, hot pepper, tomatoes and cucumbers.

Description

technical field [0001] The invention relates to the field of microbial fertilizers and biological pesticides, in particular to a bacillus wettable powder containing brassinolide and a preparation method thereof. Background technique [0002] American agronomist J.W.Mitchell and others studied and extracted a substance that can significantly promote the growth of bean seedlings from rapeseed pollen in 1970. It was named brassinosteroids, also known as brassin (Brassin), which is based on sterols. Plant endogenous steroid biologically active substances, British N.B.Mandava et al. refined brassinosteroids in 1978 to obtain crystals with high activity. In 1979, Grove et al determined that its chemical structure belonged to sterol lactone, so it was named brassinolide (Brassionlide). Later, dozens of bioactive brassinosteroids were extracted from other plants, collectively referred to as brassinosteroids (BRs for short), among which, the physiological activity of brassinosteroid...

Problems solved by technology

[0008] Although there are many microbial pesticide products mainly prepared by Bacillus, generally speaking, there are still problems including the disconnection between research and development and production, difficulty in formulation, poor product quality stability, backward production technology, low product consistency, and the scale of production enterprises. In addition to some problems, problems similar to other biocontrol agents also include application technology issues. For example, when using these biocontrol agents to carry out disease control, the influence of environmental factors on the effect of the agent must be considered. In the environment, temperature, moisture, PH, fungicides, metal ions, and other microorganisms will all affect the application effect of fungicides

Therefore, compared with chemical fungicides, its use effect is unstable and cannot achieve immediate results
