The present invention discloses a silicate plant induction disease resisting agent and purposes thereof. The agent is prepared from the following components by weight concentration: 60 to 80% of potassium metasilicate, 2 to 5.0% of dispersant, 0.5 to 5.0% of wetting agent, 1.0 to 2.0% of stabilizing agent, and filler. The silicate plant induction disease resisting agent is used as a biocontrol preparation for inducing the disease resisting reaction of plants, regulating the growth and development of plants as well as the quick reaction of cell surfaces, and directly restraining the growth and development of pathogenic bacteria and is used for preventing and treating powdery mildew, scab, gray mold, blight, rust disease, rice blast and banded sclerotial blight. The silicate plant induction disease resisting agent has no toxicity or side effect and has no harm to people or domestic animals. The silicate plant induction disease resisting agent has the advantages of no environmental pollution, good preventing and treating effect on fungal diseases of crops, no special disease resistance of plants after repeated use, mature production technology, low production and use cost, and broad application prospect. The present invention provides the nontoxic nuisance-free biocontrol disease resisting agent with low cost and high efficiency for agriculture.

Description

The agent of silicate plant inducing anti-disease
Technical field
The present invention relates to the agent of nuisance-free plant inducing anti-disease, relate in particular to the agent of a kind of silicate plant inducing anti-disease.
Background technology
Along with human living standard's raising, people more and more pay attention to the quality of food, and require more green health food.At present, the main chemical pesticide that uses is prevented and treated diseases and pests of agronomic crop, the use of chemical pesticide has strengthened the pesticide resistance of pathogen, also field ecosystem has been produced adverse influence, this just requires to reduce various pollution source, comprise and do not use or limit the use chemical pesticide, to alleviate harm human health.Therefore how to strengthen the disease resistance of plant itself, particularly improve system acquired disease-resistant have important theoretical and the practical significance of plant.Application for patent 1265831A provides a kind of peroxide soluble powder to be used for controlling plant diseases, mainly contains solid peroxide, spreading agent, sticker, stabilizing agent and filler etc., is used to prevent and treat multiple diseases such as powdery mildew, fusarium wilt, rust.Application for patent 1365832A provides a kind of calcium peroxide wettable powder to be used for controlling plant diseases, mainly contains calper calcium peroxide, dispersant, wetting agent, stabilizing agent etc., is specifically designed to fungal diseases such as powdery mildew, rust, gray mold.Application for patent 1299588A provides a kind of oligosaccharide to make biological pesticide control corps diseases, with oligosaccharide control sterilization disease with sp act, as: head blight, banded sclerotial blight, powdery mildew, rust, anthracnose etc.Application for patent 1327731A provides a kind of plant biocide without damage to that can prevent and treat plant pest, and it is obtained by alkyl benzene sulphonate and alcohol reaction, and this compound dilute with water is sprayed at the crops surface, can prevent and treat the powdery mildew, downy mildew of plant etc.Patent application 1345540A provides a kind of fungus sporophore extract to be used for the inducing plant disease resistance, is mainly used in the cucumber and the tomato plant that spray vegetative period, is used to induce the also system of defense of activated plant self disease resistance, thereby reaches the purpose of preventing and treating disease.
Summary of the invention
The purpose of this invention is to provide the agent of a kind of silicate plant inducing anti-disease.
Consisting of of it: the silicon potash fertilizer percentage by weight is 60~80%, dispersant 2~5.0%, wetting agent 0.5~5.0%, stabilizing agent 1.0~2.0%, all the other fillers.
The present invention provides a kind of brand-new application for the application of silicon on agricultural, applying silicon hydrochlorate preparation is done the plant disease-resistant agent, there are not any toxicity and other side effect, to the person poultry harmless, free from environmental pollution, fungal disease control efficiency to crop is good, and repetitive administration can not make plant produce special 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 and ecological methods to prevent plant disease, pests, and erosion antiviral agents, have a extensive future.The present invention proposes with having the biological prevention and control agent of special water miscible silicate as the control corps diseases, the reaction of inducing plant disease resistance, the fast reaction of coordinate plant growth growth and cell surface, can directly suppress growth of pathogenic bacteria again grows, to the control of farm crop fungus disease, has good effect especially.
Embodiment
The preparation method of silicate plant inducing anti-disease agent is:
It with weight concentration 60~80% silicon potash fertilizer, weight concentration is 2~5.0% dispersant, weight concentration is 0.5~5.0% wetting agent, weight concentration is 1.0~2.0% stabilizing agent, add in the premix machine with filler and to mix, dry 24h below 40 ℃ pulverizes twice with micronizer then, sieve packing with 500 mesh sieve.
Above-mentioned silicate molecular formula is K 2SiO 32H 2O.Dispersant is: one or more of calcium dodecyl benzene sulfonate, calcium lignosulfonate, NNO.Wetting agent is: one or more of lauryl sodium sulfate, fatty alcohol polyoxy ethyl ether sodium sulphate, alkyl phenol polyoxy ethyl ether sodium sulphate.Stabilizing agent is: one or more of absorbent-type stabilizing agent or solvay-type stabilizing agent, and wherein, the absorbent-type stabilizing agent is fatty acid magnesium, polyacrylamide, poly, CMC; The solvay-type stabilizing agent is NTA, EDTA, DTPA, sodium tartrate, salicylic acid, sodium alginate, DTPMP, polyacrylic.Filler is: one or more of urea, talcum powder, calcium based diatomite, white carbon.
