Abstract
The wettable powder of disease-preventing microbial pesticide has effective component as fermented product of two kinds of bacillus and named as BSN. Its production process includes screening bactericidal strain BSN from soil, inoculation culture, culture in fermentation tank, adding stabilizer and assistant, and spray drying. The said wettable powder is white, and has grain size smallar than 110 microns, bacteria content of 1E10 to 3E10 each gram, high pesticidal effect, stable quality, no environmental pollution and other advantages.
Description
Technical field: the present invention relates to a kind of microbial pesticide, particularly a kind of from soil the bacillus category microbial pesticide of isolated called after BSN.
Background technology: along with the development of green agriculture and the variation of social desirability, utilize living body biological more and more higher as the trend of agricultural chemicals in recent years, each developed country of the world is being the agricultural chemicals of effective ingredient with microorganisms such as bacterium, fungies at active development just.Find that by consulting documents and materials in a large number various countries are all more active aspect the microbial pesticide development.But microbial pesticide exists all that living microorganism is stored time-to-live weak point, fermenting and producing protection effect instability, protection effect is not high and can not with shortcoming such as other combined use of pesticides, be difficult to suitability for industrialized production.It is the wetting powder of active ingredient in 1998 with bacillus subtilis [(Bacillussubtilis (Ehrenberg) Cohn) is called for short BS] that Japan got permission registration, is the pure product of a kind of single microbial inoculum, is used to prevent and treat eggplant, graw mold of tomato.Chinese patent discloses " a kind of bacillus subtilis strain, method for making, preparation and application " (number of patent application: 98124889.6), this invention bacterium source is in the apple fruit surface, be bacillus subtilis (Bacillus subtilis), be numbered XM16, culture presevation is numbered CGMCCNo.0372; With protein, starch and sucrose is primary raw material, carries out separation and Culture and thalline production; Former bacterium culture is pulvis after pulverizing, or former bacterium powder 1-99 part mixes with 99-1 part bentonite and kaolin, is mixed with wetting powder; Be used for the control of crop fungal diseases such as mould worry of apple and trunk disease;
Summary of the invention: the purpose of this invention is to provide a kind of overcome the prior art defective,
The nothing that the plant soil-borne disease is had wide prevention and treatment range and higher control efficiency
Public hazards green micro organism agricultural chemicals.Purpose of the present invention realizes by following scheme: a kind of
Wettable powder of disease-preventing microbial pesticide, its active ingredient are called after BSN
Product behind two kinds of bacillus strain fermentations;
One of above-mentioned two kinds of bacillus bacterial classifications are bacillus subtilis (BS) N1
Number bacterial strain, another kind is a bacillus bacterial classification N2 bacterial strain;
The content of the every gram of its effective bacterium is: 1 * 10
10Individual～3 * 10
10Individual;
Its production technology is: from soil screening bacterial classification BSN, inoculated and cultured, fermentation tank culture, add stabilizing agent and auxiliary agent, atomized drying.
Microbial pesticide of the present invention belongs to wetting powder, and white, fineness are less than 110 μ m, and content is 1 * 10
10Individual～3 * 10
10Individual effective bacterium/g has advantages such as control efficiency height, steady quality, non-environmental-pollution, storage tolerance (more than 3 years) transportation; Can be used as plant seed dressing and foliar spray agent and use, and can with other chemical pesticides and with or use with; Prevent and treat various crop diseases such as take-all, protection ground vegetables damping off, the gray mold of dampinging off and bacterial epidemic disease; Have effects such as kill plants pathogen and enhancing plant resistance to environment stress simultaneously.
Embodiment: the main component of microbial pesticide of the present invention is 2 kinds of bacillus of separation screening from soil: i.e. bacillus subtilis [(Bacillus subtilis (Ehrenberg) Cohn, be called for short BS)] N
1Number bacterial strain and another kind of bacillus (Bacillus sp) N
2Number bacterial strain adds stabilizing agent after (5d) by fermentation and multiple auxiliary agent is compound formulated behind high-pressure spray-drying.Its production technology is:
BSN bacterial classification → seed is irritated inoculated and cultured (3d) → culture transferring to fermentation tank culture (5d) → add stabilizing agent and auxiliary agent → discharging → high-pressure spray-drying → packing.Product B SN microbial pesticide belongs to wetting powder, and white, fineness are less than 90 μ m, and content is 2 * 10
10Effective bacterium/g, wherein, the aforementioned stable agent is: PGA, CMC-Na, xanthans; Auxiliary agent is: B, Fe, Zn plasma.
Claims (4)
