Description
Technical field
The present invention relates to disinfectant use in agriculture field, be specifically related to bactericidal composition and the application thereof of a kind of probenazole-containing and thifluzamide.
Background technology
Rice sheath blight disease is by the popular disease in the microbial worldwide scope of miliary damping-off, one of most important disease on Ye Shi China paddy rice.Its distribution widely, has generation in each paddy rice main producing region of China, and especially in In Middle And Lower Reaches of Changjiang River and South China, harm is very serious, causes output sharply to decline.Selection and popularization disease-resistant variety is one of important measures of the water prevention rice sheath blight, in recent years, although Chinese scholars achieves a lot of progress in breeding for disease resistance, there is no at present and selects the completely immune rice varieties of rice sheath blight disease.Current Rhizoctonia solani Kuhn control still depends on chemical control.Current China adopts the medicament based on jinggangmeisu on the water prevention rice sheath blight always, namely reaches about 15% in rice tillering diseased plant rate in latter stage at the initial stage of a disease and starts to spray medicine control, and achieve certain effect.But existing report display, China's some areas rice sheath blight disease creates pesticide resistance to jinggangmeisu, and the control efficiency of this medicament caused constantly declines.If continue to control rice sheath blight disease, especially the surrogate-data technique of the water prevention rice sheath blight is filtered out, administer jinggangmeisu pesticide resistance simultaneously and promote the sustainable control of rice sheath blight disease, having become the significant challenge that numerous scientific workers and Rice Cropping person face.
Probenazole belongs to benzimidazole germicide; a kind of efficient, wide spectrum, systemic fungicide; the plurality of plant diseases such as penicilliosis, anthracnose, gray mold, scab, powdery mildew of orange storing disease, banana disease, wheat scab, bakanae disease of rice, apple core pears can be prevented and treated; protective effect and therapeutic action are had concurrently to control of plant disease; various crop disease can be prevented and treated, with jinggangmeisu without mutual pesticide resistance.
The chemical name of probenazole: 2-(4-thiazolyl)-1H-benzimidazole.
The chemical structural formula of probenazole is shown below:
Thifluzamide is again thiophene fluorine bacterium amine, it is the phenyl amide compound containing thiazole ring, belongs to succinate dehydrogenase inhibitors, has strong Uptake and translocation and long lasting effect, can prevent and treat various crop disease, particularly the fungus-caused disease of basidiomycetes Rhizoctonia has good control efficiency.Its Main Function mechanism suppresses succinate dehydrogenase in germ tricarbonic acid cycle, causes thalline dead.Thifluzamide all has activity to pathomycetes such as Rhizoctonia, Puccinia, Ustilago, Tilletia, corticium, nuclear cavity Pseudomonas, especially special efficacy is had, with jinggangmeisu without mutual pesticide resistance to the fungus-caused disease of Basidiomycetes such as banded sclerotial blight, damping off etc.
The chemical name of thifluzamide: the bromo-2-methyl of 2', 6'-bis--4'-trifluoromethoxy-4-Trifluoromethyl-1,3-thiadiazoles-5-hydroxyl anilide
The chemical structural formula of thifluzamide is shown below:
Probenazole and thifluzamide bacterium are lower toxicity or micro-virus kind agricultural chemicals, belong to efficient, low toxicity, environmentally friendly type bactericide.Probenazole mainly acts on the cell division of fungi, the succinate dehydrogenase of thifluzamide effect and thalline, thus the object reaching sterilization, there is not mutual pesticide resistance in the two.But a lot of research shows, if these two kinds of medicaments are used alone controlling disease, can pathogen are made in the short period of time to develop immunity to drugs, cause preventive effect to reduce, even prevent and treat failure.Fungicide resistance Action Committee (FRAC) advises, is used by the composite reagent of different mechanism of action, can avoid or delay drug-fast generation.Therefore, the two is combined as bactericidal composition, what effectively can not only solve rice sheath blight disease prevents and treats problem, and can avoid or delay pathogen and develop immunity to drugs to it.
Summary of the invention
The invention provides the bactericidal composition of a kind of probenazole-containing and thifluzamide, there is bactericidal activity high, delay pathogen pesticide resistance emergence and development, and dosage total in unit are is declined, economic, efficient, environmental protection.
Technical scheme of the present invention is:
The microbicide compositions of a kind of probenazole-containing and thifluzamide, it is characterized in that, the active component of described microbicide compositions is probenazole and thifluzamide, and the mass ratio of thifluzamide and probenazole is 1:20 to 20:1, and in composition, active component mass percentage is 5-60%.
Described active component thifluzamide and the mass ratio of probenazole are 1:10 to 10:1.
Described thifluzamide and the mass ratio of probenazole are 1:3-8.
Described thifluzamide and the mass ratio of probenazole are 1:4-6.
The formulation of described microbicide compositions is suspending agent, missible oil, water dispersible granules or wetting powder.
This microbicide compositions has higher control efficiency to various crop disease, particularly remarkable to rice sheath blight disease controlling effect, for the control of rice sheath blight disease and false smut.
Remarkable result of the present invention and advantage are:
Two classes are had the bactericide of different mechanism of action by the present invention, namely benzimidazole germicide probenazole and SDHI series bactericidal agent thifluzamide combined, and be processed into the upper easy-to-use preparation of production, biologically active is high, dosage total in unit are declines, greatly reduce dispenser cost, delaying pathogen pesticide resistance emergence and development to a greater extent simultaneously, reduce disease fungus produces resistance risk to single bactericide, extend the service life of each component in bactericidal composition, thus reach effect that is economic, efficient, environmental protection.
The present invention has higher control efficiency to crop fungal disease, there is notable synergistic effect between two components; Part high price pesticide species can be replaced, and reduce dosage, effectively reduce ecological disruption and environmental pollution, and crop yield and quality can be improved; In the present invention, probenazole and thifluzamide all belong to the toxicity such as low, and to people and animals, beneficial organism, Environmental security; The pesticide resistance of germ to single medicament can be delayed.
First the EC of probenazole and thifluzamide two single compound (hereinafter referred to as medicament) is measured
50(drug safety index), according to the EC of two single medicaments
50set the portfolio ratio of two medicaments by Wadley method, and according to Wadley coefficient of synergism C value, determine suitable composition ratio, then verified by the abundant method of Sun Yun.
