Description

A kind of composite plant extract liquid as agricultural disinfectant

The invention belongs to pesticide field, specifically be a kind of be the disinfectant use in agriculture of active ingredient with the various plants extract.

At present, the bactericide overwhelming majority that uses of controlling plant diseases is a chemical agent.Chemical bactericide is wide in variety, and class is complete, stable processing technology, and the rule of origin abundance has been brought into play main effect for many years aspect controlling plant diseases.But the deadly defect of chemical pesticide is that environmental pollution is serious, and along with the enhancing of environmental consciousness, it is raw material that people begin to turn to the natural plants, develops new nuisanceless disinfectant use in agriculture in recent years.

Utilize plant extraction liquid to make disinfectant use in agriculture, can trace back to before the several years, allicin be exactly early be one of bactericide of main component with the plant extraction liquid.Facts have proved that it has the better prevention effect to the various crop disease.But in use, we find that also the weakness of allicin is the preparation instability, and storage life is too short, are easy to lose efficacy, so not high always as its market occupancy volume of a kind of commodity.Over past ten years; move and inspire down at the strong desire of " protection environment ", some inventors of China begin the traditional medicine based on motherland, are primary raw material with traditional Chinese herbal medicine; screen and processed multiple disinfectant use in agriculture, and on the control fungal disease, use.For example, there are human garlic, genseng, the sophora bud, felwort preparation to prevent and treat apple valsa canker, the people arranged then with the coptis, golden cypress control vegetable fungi disease.More than prescription has all been obtained certain effect, but comprehensively it seems, still has the deficiency of two aspects: the one, selected the valuable Chinese herbal medicine less, on the high side of partly originating for use, and must cause the raising of peasant's drug cost; The 2nd, fungicidal spectrum is extensive inadequately, and they focus mostly in the fungal disease prevention and control field.To some chemicalses be difficult to prevent and treat bacillary, particularly viral disease-controlling effect is not ideal enough.

The objective of the invention is to: providing a kind of is that main component processes with the medicinal plant compound extracted solution, technology is simple, preparation stabilization, noresidue, pollution-free, nuisanceless and with low cost, can be used in the composite plant extract liquid as agricultural disinfectant of preventing and treating various crop fungi, bacterium and virus disease.

The prescription and the processing method of bactericide provided by the present invention are as follows:

A, composite family cauline leaf 20-40%, wormwood artemisia class 15-30%, tobacco 10-25%, sophora bud 10-25%;

B, above-mentioned raw materials is crushed to powder less than 5mm after, the clear water that adds 10 times of this raw material gross weights at normal temperatures soaked 24 hours, be warming up to 100 ℃ then, boiling was extracted 1 hour, leave standstill cooling back elimination raw material residue and get its clear liquid, add the preservative of gross weight 0.5-1%, can be distributed into commodity selling after mixing.

In order to improve the control efficiency of medicament targetedly to certain crop pest, more than can add a kind of in the following raw material or some kinds in the prescription, the percentage of its consumption and base stock total amount is: Huang Cen 0-15%, felwort 0-10%, Radix Angelicae Sinensis 0-10%, crotons 0-5%.The fill a prescription bactericide of processing of the present invention can suppress the activity of pathogenic bacteria enzyme, destroy the albumen form, can be used for preventing and treating the multiple plant disease that causes by fungi, bacterium and virus, as multiple diseases such as apple valsa canker, ring spot, anthracnose, cotton boll rot disease, anthracnose of grape, pear scab, soft rot of Chinese cabbage, vegetables damping off, capsicum, tomato virus disease, wheat rosette stunt, corn short mosaic diseases.

Material of germicide wide material sources of the present invention, processing technology is simple, and use cost is low, and this preparation is nontoxic to people and animals, and noresidue is pollution-free, and is safe in utilization, and the shelf-life can reach more than 2 years.
