Description
Technical field
The present invention relates to a kind of bactericidal composition, especially a kind of combination sterilization composition that contains rice blast acid amides and antibiotic.
Background technology
Paddy rice is one of staple food crop of China, and its cultivated area accounts for 1/4 of national arable area, and annual production accounts for 1/2 of national total grain output, but the endangering of annual because rice disease, and the underproduction reaches 20%-40%.Rice blast, banded sclerotial blight generation area are big, and popular strong, harm is serious, is the important disease on the paddy rice.Along with the long-term use of conventional dose such as tricyclazole, Isoprothiolane, carbendazim, the pesticide resistance of rice blast fungus and sheath blight fungus is more and more serious, and control efficiency descends.Because the germ resistance strengthens, and causes frequent dispenser again and causes peasant burden to increase the weight of and increasing environmental pollution.Therefore, be badly in need of the new type bactericide of efficient, safety, environmental protection.
Rice blast acid amides (Fenoxanil) is a kind of novel, acid amide fungicides efficiently, has good interior absorption and lasting effect, stops infecting of Pyricularia oryzae by suppressing germ from penetrating of appresorium, is the melanin biosynthesis inhibitor.The rice blast acid amides has good crop safety and outstanding Environmental compatibility, but its drug cost height uses not extensive.
The Fungicidal substance that antibiotic is in the microbial metabolism to be produced has and suppresses other growth of microorganism and grow, and the effect that hinders its physiological function.Agricultural antibiotic has the drug effect height, and selectivity is strong, easily decomposes, and residual hazard is low, and is free from environmental pollution to the person poultry safety, advantages such as easy popularization.But, long-term use separately, preventive effect descends, and germ is developed immunity to drugs.
In view of this, the necessary efficient bactericidal composite that uses on a kind of suitable agricultural that provides.
Summary of the invention
The purpose of this invention is to provide a kind of efficient, safety, environmental protection and help the combination sterilization composition that contains the rice blast acid amides of germ resistance management.
In order to achieve the above object, rice blast acid amides combination sterilization composition of the present invention is by rice blast acid amides (A) and a kind of composite forming of antibiotic (B) that is selected from kasugarnycin, polyoxin etc., wherein the mass ratio of A and B is 30: 1～1: 50, and all the other are to allow in the agricultural chemicals to use and the acceptable auxiliary element.
As a kind of improvement of the present invention, effective constituents A and B preferable quality ratio are 10: 1～1: 20,
Antibiotic in the technical solution of the present invention is specially:
Kasugarnycin (Kasugamycin) is the metabolite that actinomycetes produce, and inhales antibiotic in belonging to, and has treatment and prevention effect concurrently, and Pyricularia oryzae is had had strong inhibitory effects.
Polyoxin (Polyoxin) is the metabolite that streptomyces aureus produces, belong to the broad-spectrum antibiotics series bactericidal agent, have interior preferably absorption, disturb the biosynthesis of somatic cells wall, can also suppress germ and produce spore and scab expansion, diseases such as rice sheath blight disease are had preventive effect preferably.
Bactericidal composition of the present invention can be prepared into known method and be fit to any one formulation that agricultural is used, reasonable formulation is wetting powder, suspending agent, water dispersible granules, aqueous emulsion and microemulsion, and content of effective is 5%-70% in the preparation.
The auxiliary agent that uses in the composition of the present invention comprises that solvent, dispersant, emulsifier, stabilizing agent, antifreezing agent, wetting agent etc. and other are of value to the known substance that active ingredient is stablized and drug effect is brought into play in preparation, all be the various compositions of using or allow use in the pesticidal preparations always, be not particularly limited, concrete composition and consumption require to determine by simple experiment according to prescription.
Product described in the invention can the finished product preparation form provide, and promptly each material mixes in the composition, and the composition of composition also can provide with single agent form, directly directly mixes in bucket or jar before the use, is diluted to required concentration then.
Bactericidal composition of the present invention is mainly used in control rice blast and rice sheath blight disease.Composition of the present invention can be used by common method, and as cast, injection, spraying, dusting, scatter or be fuming, its amount of application is with weather condition or crop state variation.
Compared with prior art, beneficial effect of the present invention is: 1. composition is made up of two kinds of different active ingredients of mechanism of action, have obvious role in synergism after being mixed, improved control efficiency, simultaneously also help overcoming and delay the drug-fast generation of germ; 2. medicament is mixed and has reduced dosage, thereby has reduced cost and the pollution that has alleviated environment.
Embodiment
The combination of active principles of different agricultural chemicals is made agricultural chemicals, is a kind of mode effectively and efficiently that exploitation at present and development novel pesticide and control agricultural go up the resistance germ.The agricultural chemicals of different cultivars shows three kinds of type of action after mixing usually, and promptly summation action, synergistic effect and antagonism act on but which kind of is specially, and be unpredictable, has only by a large amount of tests and just can know.Compound synergic is well filled a prescription, and can obviously improve actual control efficiency, and reduce the usage amount of agricultural chemicals, thereby help to delay the drug-fast generation speed of germ, be the important means of integrated control disease.
The inventor is by a large amount of screening tests, find that antibiotic combination antagonism Pyricularia oryzae, sheath blight fungus etc. such as rice blast acid amides and kasugarnycin or polyoxin have remarkable role in synergy, and be not only the simple addition (seeing biologicall test example 1,2 for details) of two kinds of medicaments.
