Abstract
The present invention uses ologosaccharide extract with bio-activity to prevnet and treat diseases of crops, specially to prevent and treat fungus disease. Said invention can be used for preventing and treating bakanae disease, banded sclerotial blight, powdery mildew, blight, rust, anthracnose and dark mildew, and can obtain good control effect, and it has no residuum, and toxicity, does not pollute environment, can be repeatedly used, does not make plant produce specific disease-resistnace, and its cost is low.
Description
The oligosaccharide element that the present invention relates to a kind of harmless boilogical control agricultural chemicals, particularly a kind of biologically active is applied to biological pesticide, the disease of control crops.
Along with human living standard's raising, people more and more pay attention to the quality of food, and the more green health food of demand.At present, mainly use chemical pesticide that diseases and pests of agronomic crop is prevented and treated, the residue of agricultural chemicals has brought huge threat to people are healthy, so press for new efficient, the nontoxic public nuisance-free agricultural chemicals of research and development.Patent 95110022.x provides a kind of " bactericide " Fenjunling " without environmental pollution ", mainly contain thick tomato extract, thick bocconine extract or compositions such as nicotine extract, Escin concentrate, be specifically designed to the fungal disease of killing vegetables, melon and fruit, the white powder fungus diseases is had special efficacy; Patent 95107415.6 provides a kind of " multi-purpose, no-polution composite agricultural chemicals for plants and manufacture method thereof ", and by 16 kinds of Chinese herbal medicine preparations such as crotons, soap Huang, Chinese prickly ash, trifoliate jewelvine, its consumption is few, and the kill pests kind is many, to the person poultry harmless.Technology and patent application with Chinese herbal medicine or plant extraction liquid used as pesticides also have a lot, owing to aspect reasons such as its extraction process or effects, all do not have application so far.Oligosaccharide is a kind of carbohydrate, is mainly used in aspects such as food, health products, medicine.Provide " bacteriostatic of oligosaccharide compound " as patent 96196047.7, treatment Diplococcus pneumopniae, Hemophilus influenzae, haemophilus parainfluenzae, Pseudomonas cepacia and its mix microbial respiratory infection diseases." a kind of carrot food that is rich in two qi factors " that patent application 97104459.7 provides is made up of carrot finely processed product and oligosaccharide, flavouring, edible safety, economy, effective.
The purpose of this invention is to provide the new purposes of a kind of oligosaccharide in biological pesticide, with disease, open up sugared new application, to the person poultry harmless with the plain control of bioactive oligosaccharide crops, free from environmental pollution, reuse and can not make plant generation specificity disease resistance.
Oligosaccharide element of the present invention is complicated carbohydrate, is special oligosaccharides, also claims oligosaccharide (oligosaccharins), biologically active.The oligosaccharide element can be obtained by the fungal cell wall polysaccharide, obtains from plant cell wall polysaccharides, obtains from fungi and plant glycoprotein.
The present invention proposes with having the biological pesticide that bioactive oligosaccharide is the control corps diseases, and the inducing plant disease resistance is reacted, and the fast reaction of coordinate plant growth growth and cell surface can directly suppress growth of pathogenic bacteria again and grow.To the control of farm crop fungus disease, has good effect especially.
Embodiments of the invention are as follows: screen rational technology, produce the oligosaccharide element, be made for Pesticidal products, use by dilution.For example, produce the product of oligosaccharide cellulose content 〉=0.4%, be directly used in through dilution and spray the crops diseases prevention.
Oligosaccharide is applied to prevent and treat head blight.In the crops, the head blight of wheat is commonplace, and some local morbidity is comparatively serious, and its disease tassel yield is up to more than 50%, and the order of severity reaches 20, and disease refers to reach more than 10.The oligosaccharide element is prevented and treated wheat scab good effect, and it uses concentration is 5～50ppm, and general preventive effect can reach more than 80%.
The oligosaccharide element is applied to prevent and treat powdery mildew.The powdery mildew of rubber is the disease that has a strong impact on rubber production, and the incidence of disease is higher, uses the powdery mildew of the plain control of oligosaccharide rubber, and concentration is 10ppm, can obtain to be equivalent to the control efficiency of standard pesticide Cosan.
The oligosaccharide element is applied to prevent and treat banded sclerotial blight.Rice sheath blight disease is one of main disease of paddy rice, is only second to rice blast, mainly with the organic bactericide control, uses the oligosaccharide element and prevents and treats rice sheath blight disease, and concentration is that 5～50ppm sprays, and its control efficiency reaches more than 80%.
The oligosaccharide element also can be used for crops prevent and treat fusarium wilt, rust, anthracnose, dark mildew, etc. fungal disease, its spraying concentration is 5～50ppm, has good control efficiency.
The acquisition of oligosaccharide element can be adopted the method for the patent application 99117102.2 of our unit, with vegetable material carry out enzymolysis, deactivation, filtration, separation, concentrate the aqua finished product, during application, the concentration dilute with water sprays and gets final product on request.
The present invention provides a kind of brand-new application for the oligosaccharide element, use carbohydrate--oligosaccharide in biological pesticide, there are not any toxicity and other pair effect, to person poultry harmless, free from environmental pollution, fungus disease control efficiency to crop is good, and repeated use can not make plant produce the specificity disease resistance; Its mature production technology, produce and use with low cost, have remarkable economical and social benefit, for agricultural provides low-cost, efficient, nontoxic nuisanceless biological pesticide.
