Abstract

The invention discloses a traditional Chinese medicine composition for preventing and controlling crop pest and preparation method of the traditional Chinese medicine composition, relates to an agricultural medicament for preventing and controlling crop pest, and belongs to the field of novel pesticides. The traditional Chinese medicine composition is characterized by comprising the following raw materials by weight percent: 5-10% of Chinese honeylocust fruit, 5-10% of radix scutellariae, 15-20% of radix isatidis, 5-10% of liquorice, 5-10% of caulis bambusae in taeniam, 25-35% of longstamen onion bulb, 15-20% of stabilizer, and 5-10% of penetrating agent; the above raw materials are decocted for 40min. The traditional Chinese medicine composition has the beneficial effects that effective ingredients of the traditional Chinese medicine preparation can directly achieve disease tissue of the tree body to kill the germ cells through reasonable ratio; not only can the germs be completely killed, but also the bark and the tree body cannot be injured; the field dosage is greatly reduced, the environment pollution and pesticide residue are effectively reduced, and the production cost and the use cost are lowered; the action mechanisms of the effective ingredients in the sterilizing composition are different from each other so that the disease resistance is overcome and the production of the disease drug resistance is delayed.

Description

A kind of Chinese medicine composition for controlling crop diseases and insect pests and preparation method thereof

Technical field

The present invention relates to a kind of medicament of agricultural controlling crop diseases and insect pests, belong to novel agrochemical field, specifically a kind of Chinese medicine composition for controlling crop diseases and insect pests and preparation method thereof.

Background technology

Applied chemistry synthetic pesticide, it has preventive effect good, acts on fast feature, is one of important means of the extermination of disease and insect pest at present.But long-term a large amount of chemical synthetic pesticide of use unreasonably, the application of especially high poison, persistent pesticide, causes and causes residue of pesticide to exceed standard, environment and agricultural product contaminated, harm human and livestock health; It is serious that damage by disease and insect develops immunity to drugs, preventive effect reduces even killed natural enemies, causes damage by disease and insect rampant again, destroy the ecological balance." 3R " problem of Here it is so-called chemical pesticide.

The negative effect caused because of improper use or the abuse of chemical pesticide is apparent.Botanical pesticide has low toxicity, noresidue, to the feature such as natural enemy is safer, meanwhile, its complex chemical composition of botanical pesticide, not easily develops immunity to drugs.Therefore botanical pesticide is for the comparatively ideal class public nuisance-free agricultural chemicals of solution chemical synthetic pesticide " 3R " problem.One of reply international agriculture trade Green barrier and the important means of producing green, organic food.Recent two decades comes, and the research and development of botanical pesticide and application progressively obtain the attention of insider, and obtain certain development.

Current research botanical pesticide has two objects, and one is find pesticide activity component from plant, and as the lead compound of the new chemical pesticide of synthesizing efficient low toxicity, two is that direct appliable plant resource makes botanical pesticide.Mostly be the first object abroad.Domestic because of plant resources enrich, be main mainly with the second object.Current China has various plants patent or product comes out, but the overwhelming majority is plant insecticide, relates to botanical fungicide then very few.

The present invention selects the root of Chinese wild ginger on a large amount of screening operation basis, and turmeric and kuh-seng three kinds of Chinese herbal medicines are the composition of raw material.The superiority of prescription is: it is the Herba Asari volatile oil of active ingredient, curcumin, turmerone and multiple matrine that the active component of-Plants comprises with methyl eugenol, a few active component is worked in coordination with mutually, can have inhibitory action to multiple target pathogens, fungicidal spectrum is wider; Three Plants combinations are compared with single plant, and its preparation drug effect is close, also has synergistic effect (the results are shown in Table 1) to American Ginseng rhizoctonia solani, can reduce costs simultaneously.In addition, because active component adheres to dissimilar compound separately, therefore not easily develop immunity to drugs.

Summary of the invention

For achieving the above object, the invention provides a kind of Chinese medicine composition for controlling crop diseases and insect pests and preparation method thereof, provide a kind of for existing medicine weak point and be applicable to efficient bactericidal composite that agriculturally use, that disease is had to outstanding control efficiency.

A kind of Chinese medicine composition for controlling crop diseases and insect pests of the present invention, is characterized in that: be made up of the raw material of following weight proportion: Chinese honey locust 5 ~ 10%, the root of large-flowered skullcap 5 ~ 10%, isatis root 15 ~ 20%, Radix Glycyrrhizae 5 ~ 10%, caulis bambusae in taenian 5 ~ 10%, Longstamen Onion Bulb 25 ~ 35%, stabilizing agent ooze 15 ~ 20%, bleeding agent 5 ~ 10% forms; Decoct 40min.

Described stabilizing agent is salicylic acid.

Described bleeding agent is polyvinyl alcohol.

A kind of Chinese medicine composition for controlling crop diseases and insect pests of the present invention and preparation method thereof, is characterized in that:

One, by the Chinese honey locust 5 ~ 10% of drying, the root of large-flowered skullcap 5 ~ 10%, isatis root 15 ~ 20%, Radix Glycyrrhizae 5 ~ 10%, caulis bambusae in taenian 5 ~ 10% pulverize, cross 40 mesh sieves, respectively or mixing solution soak 24h;

Two, under counterflow condition, difference or mixing are extracted, Extracting temperature 80 DEG C, and extraction time 3h, extracts 2 times, and extracted twice liquid merges, and is concentrated by extract and is dissolved to 1/3 of crude drug weight, for subsequent use;

Three, in a kettle., add that stabilizing agent oozes 15 ~ 20% by Longstamen Onion Bulb 25 ~ 35%, in bleeding agent 5 ~ 10%, fully mixing can obtain bactericide at 50 DEG C.

The Chinese medicine composition of described controlling crop diseases and insect pests is colourless micro-yellow liquid, nontoxic, non-environmental-pollution, person poultry safety, uses simple, easy to operate; Production technology is simply accurate, with low cost, practical; The composition of composition provides with unit dose form, directly directly mixes in bucket or tank, be then diluted to required concentration before using.

A kind of Chinese medicine composition for controlling crop diseases and insect pests of the present invention and preparation method thereof, its beneficial effect is: by rational scientific composition and proportioning, the active ingredient of Chinese medicine preparation and high-efficiency activated dose directly can be arrived tree body disease portion tissue, kill germ cell, not only sterilization is thorough, do not hinder bark, tree body, reduce expenses 50%; Significantly reduce field dosage, effectively reduce environmental pollution and residue of pesticide, and reduce production and use cost; In bactericidal composition, the mechanism of action of active ingredient is different, is conducive to the generation overcoming Disease Resistance He delay disease drug resistance.Compound synergic is well filled a prescription, and owing to significantly improving actual control efficiency, reduces the usage amount of agricultural chemicals, thus has delayed the generation of disease drug resistance widely, is the important means of integrated control.
