Abstract
The invention relates to a vegetable diseases prevention and control agent containing a plant inducer, wherein the components comprise, by mass, 30-70% of polyglutamic acid, and 30-70% of chitosan oligosaccharide. The preparation method comprises: uniformly mixing polyglutamic acid and chitosan oligosaccharide according to a certain ratio. According to the present invention, polyglutamic acid and chitosan oligosaccharide are used and mixed according to the ratio, wherein 1.5-2 g of the mixture is added with water having the amount of 15000-20000 times the amount of the mixture to obtain 667 ml of the vegetable diseases prevention and control agent, and the obtained vegetable diseases prevention and control agent is sprayed and applied on the plant surface before disease occurrence, and is used for prevention and control of cucumber downy mildew, tomato gray mold, and other fungal diseases.
Description
Technical field:
The present invention relates to vegetable disease Control Technology field, be specifically related to a kind of vegetable disease prevention and control containing plant inducer
Preparation.
Background technology:
Vegetable is facility cultivation vegetable particularly, subjects to the sex pheromones such as fungus, antibacterial, virus in growth course
Infect, or coercing because of poor environment, produce pathology or physiological disturbance, such as powdery mildew of cucumber, soft rot of Chinese cabbage, tomato yellow leaf curl, Caulis et Folium Lactucae sativae freeze injury etc. Controlling vegetable disease, one individually or comprehensively adopts cultural control, physical control, Biological control, Chemical control methods. These measures have respective pluses and minuses, need according to specific time and site suiting measures to different conditions, reasonable employment in practice.
Preventing and treating vegetable disease, the more of use is to utilize disease-resistant variety and chemical prevention, but the former one breeding cycle is longer, and disease species is various, is difficult to select general anti-and colory kind. And chemical prevention instant effect, effective, but it is easily generated " 3R " problem, quality of agricultural product and environment are produced harmful effect.
Oligosaccharide, abscisic acid etc. are current widely used plant inducers, and its ultimate principle is, after using, to produce the effect of similar vaccine in pin main body, and what stop pathogen invades harm further, shows as the effect of induction of resistance. Some inducers are glucide, are easily hydrolyzed after being dissolved in water, reduce active ingredient. Simultaneously because vegetable surface one have wax coat or table and fine hair, inducer is not easily absorbed by plant after spraying, and is difficult to play Induced resistant effect.
Summary of the invention:
It is an object of the invention to provide a kind of anti-controlling agent of the vegetable disease containing plant inducer, it adopts two kinds of biological substance rational proportions, not facile hydrolysis after using, spray to be more easy to after vegetable and be absorbed by plants, induction plant produces resistance rapidly, is finally reached the effect of plant growing stalwartness, opposing disease.
In order to solve the problem existing for background technology, the composition of the present invention and mass percent be: polyglutamic acid
30 70%, oligochitosan 30 70%.
Preparation method is: proportionally mixed homogeneously with oligochitosan by polyglutamic acid.
The present invention adopts polyglutamic acid and oligochitosan, proportionally mixes, to 15,000 20000 times of water, every 667m. With said mixture 1.5 2g, spray in plant surface before disease occurs, be used for preventing and treating the fungal disease such as cucumber downy mildew, graw mold of tomato.
The method have the advantages that two kinds of biological substance rational proportions of employing, not facile hydrolysis after using, spray to be more easy to after vegetable and be absorbed by plants, induction plant produces resistance rapidly, is finally reached the effect of plant growing stalwartness, opposing disease.
Detailed description of the invention:
Detailed description of the invention one: the composition of this detailed description of the invention and mass percent be: polyglutamic acid 40%, shell are few
Sugar 60%.
Preparation method is: proportionally mixed homogeneously with oligochitosan by polyglutamic acid.
This detailed description of the invention adopts polyglutamic acid and oligochitosan, proportionally mix homogeneously, every 667m. , to water 1500) and 0 20000) times, spray in plant surface before disease occurs, be used for preventing and treating the fungal disease such as cucumber downy mildew, graw mold of tomato.
This detailed description of the invention adopts two kinds of biological substance rational proportions, not facile hydrolysis after using, and sprays to be more easy to after vegetable and is absorbed by plants, and induction plant produces resistance rapidly, is finally reached the effect of plant growing stalwartness, opposing disease.
Detailed description of the invention two: this detailed description of the invention and detailed description of the invention one are different in that its composition and mass percent are: polyglutamic acid 35%, oligochitosan 65%, its preparation method is identical with detailed description of the invention one.
Detailed description of the invention three: this detailed description of the invention and detailed description of the invention one are different in that its composition and mass percent are: polyglutamic acid 65%, oligochitosan 35%, its preparation method is identical with detailed description of the invention one.
