Description

Containing biological antibiotic composition and the application thereof of Zhongshengmycin

Technical field

The present invention relates to a kind of biological antibiotic composition containing Zhongshengmycin and application thereof, in biopesticide Prevention Technique field.

Background technology

At present, chemical control is the important measures controlling day by day serious plant disease, advantages such as there is instant effect, fungicidal spectrum is wide, cost is low, be easy to use, important function has been played to guarantee agricultural production, but long-term a large amount of use of chemical bactericide causes a series of serious ecological problem and the social concern such as agricultural chemicals pesticide resistance, residue of pesticide, environmental pollution, agricultural product security.In recent years, along with the quality safety of people to agricultural product and the concern of problem of environmental pollution, the use of chemical bactericide is subject to more and more stricter restriction.Therefore, people start more to be conceived to more low toxicity, environmental protection, free of contamination biogenic pesticide.Biogenic pesticide utilizes the antagonist properties between microorganism to prevent and treat pathogen, and this is more efficient and environmental protection than existing chemical pesticide.At present, exploitation biogenic pesticide new varieties and complex preparation are more and more subject to people's attention.

Zhongshengmycin is a kind of novel agricultural antibiotic, and its fungicidal spectrum is wide, all has good preventive effect to the bacterial disease of crops and fungal disease, can the synthesis of anti-bacteria bacterium protein, causes thalline dead; There is strong inhibitory action to fungus spore germination, cause protoplasm cohesion in hyphal cell, change the form of thread mycelia.

Shen piperazine mycin is a kind of antibiotic secreted through biological culture by pseudomonas fluorescens, main component is phenazine-1-carboxylic acid (phenazine-1-carboxylic acid), there is wide spectrum Suppressing phytopathogens simultaneously and the dual-use function of Promoting plant growth effect, this biological bactericide has wide spectrum, efficient feature, effectively can prevent and treat paddy rice, wheat, vegetables, fusarium wilt on the crops such as fruit tree, blight dis-ease, epidemic disease, banded sclerotial blight, false smut, rice blast, downy mildew, yellow rust, stalk break, head blight, anthracnose, gray mold, scab, leaf spot, bacterial wilt, canker, bacterial wilt of ginger and soil-borne disease soil treatment.

In the real process of agricultural production, a kind of medicament of use single continuously for a long time, pathogen will soon develop immunity to drugs, and causes preventive effect to reduce, and Pesticide use amount increases, the destruction of aggravation Practice for Pesticide Residue in Agricultural Products and ecotope.By carrying out composite with the mechanism of action diverse bactericide kind, being delay pathogen to develop immunity to drugs, expanding fungicidal spectrum, increasing the service life, reduce the effective way of Pesticide use amount.

In prior art, there is not yet about Zhongshengmycin and Shen piperazine mycin is composite and the relevant report applied.

Summary of the invention

For above-mentioned prior art, the invention provides a kind of biological antibiotic composition containing Zhongshengmycin, its active ingredient is Zhongshengmycin and Shen piperazine mycin, be biogenic pesticide, Zhongshengmycin, the Shen piperazine mycin mechanism of action are completely different, composite can to the effect of pathogen multidigit point, expand fungicidal spectrum, improve preventive effect, reduce Pesticide use amount, delay drug-fast generation.Present invention also offers the application that this contains the biological antibiotic composition of Zhongshengmycin.

The present invention is achieved by the following technical solutions:
