Description

A kind of bacillus subtilis water dispersible granules and preparation method thereof
Technical field
The present invention relates to a kind of bacillus subtilis water dispersible granules and preparation method thereof.
Background technology
In recent years, the food-safety problem that China's residue of pesticide cause is very outstanding, and the pesticide poisoning event that again and again occurs has constantly been beaten alarm bell to the whole society.Because of the use of a large amount of high malicious high residue chemical pesticides, cause the agricultural products in China export situation severe simultaneously, and soil, water body, atmosphere are caused severe contamination, destroy the ecological balance.Biopesticide is that pollution-free food and organic farm products are produced the indispensable means of production, and for guaranteeing agricultural product quality and safety and ecological environment security, the quality of uplifting the people's living standard has important positive effect.
Bacillus subtilis (Bacillus su] otilis) be a kind of have a liking for temperature, aerobic, sporiferous bacillus, its physiological characteristic is various, and is widely distributed, very easily separates and cultivates.This bacterium is widespread in nature, and is nontoxic to people and animals, free from environmental pollution, can produce multiple antibiotic and enzyme, has broad spectrum antibiotic activity and extremely strong anti-adversity ability.Bacillus subtilis not only can be in the external environments such as soil, plant rhizosphere body surface extensively exists, and is common endogenetic bacteria in the plant corpus, especially in root, the stem of plant.This bacterium demonstrates good disease-controlling effect crops such as paddy rice, soybean, cotton, wheat, capsicum, tomato, corns at present.The prominent features such as growth is fast because bacillus subtilis has, nutrition is simple and it is heat-resisting to produce, degeneration-resistant gemma, producing, formulation and the survival in environment, surely growing and breeding and make it not only be conducive to biocontrol fungicide, and mass production processes is simple, cost is lower, use conveniently, storage life is long, has now become a kind of desirable biocontrol bacteria.
At present, domestic bacillus subtilis formulation is take wetting powder as main, and dust is harmful to the operator when producing and using, " caking " occur when in water, disperseing and easily stop up shower nozzle, in addition, differ because the improper sedimentation that causes of prescription causes spray medicine front and back concentration, suspensibility remains further to be improved.
Water dispersible granules claims again dry suspending agent (Dry flowable, DF) or the grain type wetting powder (Granule typewettable powder), the early 1980s, a kind of pesticides new formulation of US and European exploitation, purpose is to solve pulvis and wetting powder dust pollution, the percutaneous toxicity of missible oil and the problem that suspending agent is difficult for toppling over, characteristics are good fluidities, dustiness is low, easily metering, in addition, the quick disintegration of its entry, on drug effect without impact.
Summary of the invention
The objective of the invention is to aim to provide a kind of suspensibility high for above-mentioned present situation, the spray medicine does not stop up shower nozzle, and is sprayable, but also granule is spreaded manuer in holes, bacillus subtilis water dispersible granules that control efficiency is good and preparation method thereof.
The implementation of the object of the invention is, a kind of bacillus subtilis water dispersible granules is comprised of the component of following percentage by weight:
Former powder 10~70% dispersants 1.5~11% of bacillus subtilis
