Abstract
The invention belongs to the field of pesticide, and particularly relates to a sterilization composition for preventing a rice sheath blight disease. The sterilization composition includes effective ingredients of thifluzamide and albendazole, and the mass ratio of the thifluzamide to the albendazole is (1:20) to (20:1). The sterilization composition disclosed by the invention has good control effect on the banded sclerotial blight of the rice, and has the following significant effects and advantages that 1, the sterilization effect is improved after the thifluzamide and the albendazole are mixed, and the use dosage is reduced; 2, agent characteristics are subjected to complementary advantages after the thifluzamide and the albendazole are mixed, and drug use of a peasant is facilitated; and 3, the thifluzamide and the albendazole have a little of poison without residue and have significance in resistance and comprehensive treatment of a disease.
Description
Technical field
The invention belongs to pesticide field, specifically a kind of bactericidal composition of preventing and treating rice sheath blight disease.
Background technology
Control paddy rice rice sheath blight disease mainly relies on chemical agent in the at present agricultural production, existing common fungicide jinggangmeisu and triazole type medicament are (such as Difenoconazole, propiconazole, azoles is pure, alkene azoles alcohol etc.) pesticide resistance is in various degree arranged, in the production by increasing the bactericide property of medicine, according to incompletely statistics, annual medicament for preventing and treating rice sheath blight disease reaches tons up to ten thousand, this has not only caused serious paddy field ecotope and water pollution, and directly increased the residual of toxic chemical substance in the rice, human health is threatened, and the excessive use of triazole type medicament can suppress fertility, affect Rice Heading, easily produce " luxuriant neck " phenomenon, produce at present some the external imported products such as the single preparation of thifluzamide (full fringe) that are using, cost is too high, the peasant can not accept, and reuses for a long time and can develop immunity to drugs.Therefore, " good quality and high output ' with " safety " become contradiction very outstanding in the Rice Production.
Thifluzamide also claims thifluzamide, and English common name Trifluzamide belongs to the thiazole amide bactericide, has strong interior conductivity and the long lasting effect of inhaling.Thifluzamide is the succinate dehydrogenase inhibitor, because fluorine-containing, its competitiveness in biochemical pathway is very strong, in case be combined with regard to difficult recovery with substrate or enzyme.Thifluzamide has special efficacy to the fungus-caused disease of Basidiomycetes such as banded sclerotial blight, damping off etc., and the pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, nuclear cavity Pseudomonas are also all had good preventive effect.
Albendazole also claims albendazole, and English common name Albendazole is a kind of wide spectrum systemic fungicide of efficient, low toxicity, has protection and therapeutic action, and the pathogen spore germination is had stronger inhibitory action.Its main mechanism is similar to Benzimidazole fungicides.Fungicidal spectrum is wider, and the crop pest that especially multiple basidiomycetes and imperfect fungus is caused is effective, and also effective to some bacterial diseases.
Have not yet to see be used to what prevent and treat crop pest and comprise thifluzamide and albendazole bactericidal composition.
Summary of the invention
Technical problem to be solved by this invention is that a kind of bactericidal composition of preventing and treating rice sheath blight disease of preventing and treating rice sheath blight disease, reduction pathogen pesticide resistance, reducing drug cost that can be used in is provided.
Bactericidal composition active ingredient of preventing and treating rice sheath blight disease of the present invention is thifluzamide and albendazole, the mass ratio of thifluzamide and albendazole is at 1:20 ~ 20:1, preferred proportion is at 1:10 ~ 10:1, the mass percentage content of active ingredient in preparation is 1% ~ 60%, be preferably 15% ~ 60%, all the other are to allow in the agricultural chemicals to use and the acceptable auxiliary element.Under better formula, rice sheath blight disease controlling is reached preferably effect.
The present composition can be prepared into by the method that oneself knows any one formulation that is fit to agricultural use, and reasonable formulation is suspending agent, aqueous emulsion, wetting powder, water dispersible granules.
The auxiliary agent that uses in the composition of the present invention comprises that solvent, dispersant, stabilizing agent, antifreezing agent, thickener etc. reach other and be of value to the known substance that active ingredient is stablized and drug effect is brought into play in preparation, all be various compositions commonly used in the pesticidal preparations or that permission is used, be not particularly limited, concrete composition and consumption require to determine by test according to prescription.
Composition of the present invention also can use with other compound with weeding, desinsection or bactericidal property, also can mix use with nematocide, protective agent, growth regulator, nutrient for plants or soil conditioner.
Bactericidal composition of the present invention has good preventive effect to the banded sclerotial blight of paddy rice, and has following remarkable result and advantage: the one, after thifluzamide and albendazole are mixed, improved bactericidal effect, and lowered using dosage; The 2nd, after thifluzamide and albendazole were mixed, the medicament characteristic had obtained mutual supplement with each other's advantages, made things convenient for peasant's medication; The 3rd, thifluzamide and albendazole be mixed rear little poison, noresidue, significant to resistance and the comprehensive regulation of disease.
Embodiment
In the embodiment of the invention, thifluzamide proportionings different from albendazole are to rice sheath blight disease toxicity test result such as following table:
