Description
Technical field
The invention belongs to field of agricultural fungicide, particularly a kind of novel plant source bactericide and preparation method thereof.
Background technology
Since the forties in 20th century, chemical pesticide because it is wide in variety, instant effect, easy to use, lower-price characteristic dominate in pesticide market.Yet, because people are to the unreasonable use of chemical pesticide and the intrinsic shortcoming of agricultural chemicals itself, cause chemical pesticide in use to produce the problems such as environmental pollution, person poultry poisoning, residue of pesticide.Along with the raising of people's quality of life and the enhancing of environmental consciousness, exploitation has become the new focus of pesticide field research to the biopesticide of person poultry safety, pollution-free, low toxicity, low-residual.
Botanical pesticide is as a part for biorational agricultural chemicals, and its developmental research is one of hot subject of novel pesticide research always.Botanical pesticide derives from nature, can degrade at natural world, generally do not pollute the environment and agricultural product, in environment and human body, the possibility of accumulation toxicity is little, comparatively safe to people and livestock, little to pest natural enemy injury, there is the feature of low toxicity, low-residual, can keep the high-quality of agricultural product, so botanical pesticide has wide market.In recent years, comparatively deep to the research of plant insecticide, comprise the aspects such as Insecticidal Plant Resource and distribution, insecticidal active ingredient, the mode of action, the mechanism of action and commercialization, and a little less than the research relative thin of relevant botanical fungicide.The plant defense element that botanical fungicide utilizes some antibacterial material that plant contains or induction to produce, kills or effectively suppresses growing of some pathogen.Plant is the natural treasure-house of bioactive compound, the secondary metabolite of its generation surpasses 400,000 kinds, and most of chemical substances wherein all has desinsection or antibacterial activity as terpenes, alkaloid, flavonoids, steroidal, phenols, unique amino acid and polysaccharide etc.Therefore, plant is considered to best the exploiting natural resources of chemosynthesis bactericide substitute.
Plants essential oil is flower, leaf, stem, root or the fruit from plant, refines the volatile flavor of extraction by steam distillation, extrusion, cold-maceration or solvent extraction method.Natural plant essential oils prevent infectious disease, to antibacterium, virus, mould, can anti-inflammation, anti-spasm, the functions such as cell metabolism and cytothesis that promote.The biologically active of plants essential oil is very high, and its application is not only confined to the industry such as traditional medicine, food, tobacco and wine, detergents and cosmetic, has shown very strong strength in plant protection.Therefore, plants essential oil has potential value and wide market as botanical fungicide class agricultural chemicals.
Summary of the invention
The object of the present invention is to provide a kind of botanical fungicide of pure natural, but it can kill bacterium effectively, do not injure again human body and fragrant odour simultaneously, there is the advantages such as safe and harmless, pollution-free, can also avoid the drug-fast generation of germ, be a kind of desirable bactericide.
For achieving the above object, technical scheme proposed by the invention is: a kind of botanical fungicide, is characterized in that: raw material forms and mass percentage content is:
Turpentine oil 15%-25%;
Tea oil 10%-20%;
Fragrant camphor oil 10%-25%;
Eucalyptus oil 20%-30%;
Thickener 5%-10%
Suspending agent 2%-4%
Emulsifier 5%-8%.
Further, described emulsifier can adopt OP-10(chemistry alkylphenol polyoxyethylene by name) or triton x-100 (chemistry octyl phenyl APEO by name) etc.
Further, described thickener preferably glycerine.
Further, the preferred xanthans of described suspending agent.
The present invention also comprises the preparation method of described botanical fungicide, it is characterized in that: comprise the following steps:
Step 1: turpentine oil, tea oil, fragrant camphor oil, eucalyptus oil and glycerine are added in reactor successively, stir, obtain mixture A;
Step 2: xanthans and emulsifier are joined in the reactor of mixture A, and heating, stirs, and obtains botanical fungicide, is the liquid of clear.
Further, in step 1), described mixing time is 10-15min.
Further, in step 2) in, described heating-up temperature is 40-50 ℃; Described mixing time is 10-20min.
Concrete, described novel plant source bactericide can be used by common method, as sprayed and spraying, usage amount is with weather condition or crop state variation, time of application can be before crop be susceptible or afterwards, be generally product to be directly diluted with water to 5 ‰-10 ‰ the aqueous solution use, usage amount is about 40 kg of water solution/mus.
Novel plant source bactericide of the present invention is applicable to the crops such as vegetables, melon and fruit, cereal, can be used to prevent and treat important disease in sac fungi, basidiomycetes, oomycetes as powdery mildew, rust, net blotch and gray mold etc.
Botanical fungicide of the present invention has following outstanding advantages:
1) to adopt the plants essential oil of pure natural be completely sterilization component in the present invention, realized real nontoxic pollution-free, the health that can not threaten people, green safety;
2) sterilization is wide, is applicable to the crops such as vegetables, melon and fruit, cereal, and the important disease in sac fungi, basidiomycetes, oomycetes is all had to preventive and therapeutic effect as powdery mildew, rust, net blotch and gray mold etc.;
3) can avoid the drug-fast generation of germ, there is fresh air and Disinfection Effect and fragrant odour.
