Abstract
The invention discloses a microbial pin oleoresin based plant oil suspending agent and a preparation method thereof. The method uses microbes, a solvent, a thickening agent and an emulsifier as raw materials, and comprises the following steps: firstly, pretreating the microbes and the thickening agent; secondly, mixing all raw materials together, and stirring; finally, grinding the mixture in a sand mill until the granule diameter of the mixture is less than 5 mu m, and filtering. According to the suspending agent and the production process of the suspending agent, the process is simple, the use is convenient, the production cost is low, an organic solvent is not used, the environment-friendly pressure is greatly reduced, the drug effect is high, and the quality is stable.
Description
Technical field
The present invention relates to a kind of microorganism rosin-based oil-suspending agent and preparation method thereof, belong to pesticide field.
Background technology
Energy metabolism secreting bacteria element (subtilin, polymixin, nystatin etc.), lipopeptide compound, organic acid substance etc. in microorganism growth process, these metabolites can effectively suppress the growth of pathogen, insect, weeds or dissolve pathogen, prevent and treat crop pest, insect pest and weeds, along with the problem of chemical pesticide contaminated environment becomes increasingly conspicuous, the research of microbial pesticide and producing comes into one's own more.
At home, what the research and development of the solvent of oil-suspending agent were many is epoxidation and methylated vegetable oil, is mainly derived from soybean oil, rape seed oil, cottonseed wet goods.But the intermiscibility of these vegetable oil and pesticide active ingredient is poor, it is difficult to mate with existing emulsifier, uses edible oil also to have the problem of striving food with the people; The current development and application technical research of this class unedible oil of Jatropha curcas oil is still immature.
Summary of the invention
the technical issues that need to address of the present invention are to provide a kind of minimizing dust pollution, improve agricultural chemicals result of use, environmentally friendly, have microorganism turpentine-based vegetable oil suspending agent of environmental protection feature and preparation method thereof.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
Microorganism turpentine-based vegetable oil suspending agent, is characterized in that, the percentage by weight of its each component is: microorganism 0.1-10%, turpentine-based vegetable oil 10-80%, thickener 1-10%, emulsifier 10-20%.
Described microorganism is selected from least one in microorganism insecticide, microbial bactericide.
Described microorganism insecticide is selected from least one in bacillus thuringiensis, chafer bacillus, white muscardine fungi, green muscardine fungus, Paecilomyces varioti, seat shell spore bacterium, Bacillus sphaericus, slow disease bacilli, bacillus thruingensis, Verticillium dahliae, Lagenidium giganteum, crinosity bacterium.
Described microbial bactericide is selected from least one in Trichoderma, gliocladium germ, the raw phycomycete of worm, bacillus subtilis, agrobacterium radiobacter, onion bulb sick leave monad, carrot soft rot Erwinia, bacillus licheniformis, bacillus amyloliquefaciens, pseudomonas syringae, Bacillus cercus, pseudomonas fluorescens.
Described thickener is one or more mixing of organobentonite, attapulgite, white carbon, aluminium-magnesium silicate.
Described emulsifier is one or more mixing of triethanolamine salt, polyoxyethylene sorbitol acid anhydride ester, alkylphenol polyoxyethylene, the sorbitan mono-oleic acid ester of ethylene oxide propylene oxide block polymer, Nonyl pheno rice phosphate monoester and diester mixture.
The preparation method of microorganism turpentine-based vegetable oil suspending agent, comprises the following steps: microorganism, thickener are carried out to pretreatment, then emulsifier, thickener and turpentine-based vegetable oil are mixed and stirred; Then mixed uniformly raw material is dropped in sand mill, sand milling to particle diameter is below 5um; Finally the good product of sand milling is filtered.
Beneficial effect of the present invention:
1, the invention provides a kind of green, environmental protection formulation, using turpentine-based vegetable oil as solvent, from environmental angle, it is good supplementing of water baseization, the green preparation of granulating, and it is poor to go at water stability, the agricultural chemicals that granulation is more difficult.Owing to doing carrier with vegetable oil, target is had to good compatibility, can better bring into play drug effect.Production technology is relatively simple, basic identical with aqueous suspension agent, during application, so high to auxiliary agent requirement unlike water base chemical preparation, does not substantially need to add other synergist;
What 2, the present invention used is the vegetable oil of rosin-based, cheap, than being easier to emulsification, can overcome the shortcoming of general vegetable oil solvent, and easily obtain.
3, the microorganism rosin-based oil-suspending agent that prepared by the present invention has not only solved the environmental issue that wetting powder causes, and is significantly improved than the drug effect of aqueous suspension agent.Meanwhile, solved general vegetable oil solvent expensive, be difficult for obtaining, the shortcoming such as emulsifying effectiveness is poor, and quality is unstable.
