Description
Technical field
Composition pesticide of the present invention is to be suitable for prevention by disease using fluazinam and cyflufenamid as active ingredient
The fungus-caused crop disease of the original has the fungus-caused crop disease of pathogen, especially Erysiphaceae suitable for prevention
(Erysiphales) crop powdery mildew caused by pathogen.
Background technology
Fluazinam, english common name fluazinam belong to 2,6- dinitroanilines, the chloro- N- of Chinese nickname 3-
Fluoro- 2, the 6- dinitros-p-toluidines of (the chloro- 5- trifluoromethyls -2- pyridyl groups of 3-)-α, α, α-three, are protective fungicides.Fluorine
Pyridine amine has special efficacy to a variety of gray molds caused by Botrytis cinerea.Same benzimidazole, dicarboximide class and currently on the market
Some fungicide no interactions resistances.The germs such as interlink spore genus, Phytophthora, Plasmopara, Sclerotinia and Venturia are caused
Disease also have good activity.
Cyflufenamid, english common name cyflufenamid are developed by Japanese Cao Da companies for preventing various crops
The acid amide fungicides of powdery mildew, inhibit Powdery Mildew mycelia on haustorium formation and growth, the growth of secondary hyphae and point
Sporogenic formation.Cyflufenamid is systemic fungicide, has excellent protection, therapeutic activity, holding effect activity and resistance to rainwater
Wash away activity；With numerous fungicide no interactions resistances used at present, there is excellent effect to the powdery mildew of various vegetables and wheat
Fruit and characteristic.
It is found by experiment that, fluazinam is used in mixed way with cyflufenamid to Botrytis (Botrytis), Sclerotinia
(Sclerotinia), grape Sclerotinia (Botryotinia), subcutaneous ulcer Pseudomonas (Colletotrichum), Fusicladium
(Fusicladium), there is collaboration to increase for ring Fusicladium (Sphlocaea) and Erysiphaceae (Erysiphales) pathogen
Effect acts on especially 20:1~1:There is apparent synergy to Erysiphaceae (Erysiphales) pathogen in 20 proportional regions
Effect.
Can be agriculturally common dosage form with excipient by certain technological means fluazinam and cyflufenamid composition.
Invention content
The technical issues of present invention need to solve be：Overcome in the prior art dosage it is big, it is of high cost, to ecological environment endanger

The composition pesticide containing fluazinam and cyflufenamid of white powder disease.
To solve the above problems, the technical solution adopted in the present invention is：A kind of agriculture containing fluazinam and cyflufenamid
The weight part ratio of drug composition, including usual auxiliaries, fluazinam and cyflufenamid, fluazinam and cyflufenamid is 20:1-1:
20, the weight percent of fluazinam and cyflufenamid weight summation in composition pesticide is 5%-80%.
The composition pesticide of the present invention can be configured to suspending agent, oil suspends according to well known to a person skilled in the art method
The application forms of the suitable agricultural use such as agent, water dispersible granules, wettable powder.
The composition pesticide also usual auxiliaries containing pesticidal preparations of the present invention, including it is solvent, emulsifier, wetting agent, steady
Determine one kind or several in agent, dispersant, thickener, antifoaming agent, antifreezing agent, disintegrant, binder, filler, filler, medium etc.
Kind mixing, is known substance, is common various auxiliary agents in pesticidal preparations, can be varied from, be had no according to different situations
It is particularly limited to.
The composition pesticide of the present invention is used to prevent plant disease agriculturally, is particularly suitable for by Erysiphaceae
(Erysiphales) crop powdery mildew caused by pathogen.
The composition pesticide of the present invention should occur early period in disease in application or disease early period of origination uses.
The composition pesticide of the present invention, is generally used by spray method, and can also use and agriculturally answer as needed
Other use technology.
Composition pesticide provided by the invention has the advantages that：
1, composition pesticide provided by the invention shows apparent synergistic effect, composition within a certain ratio range
Control effect be significantly improved than single dose, reduce the dosage of pesticide, reduce drug cost, reduce pesticide pair
The adverse effect of ecological environment；
2, the combination of two kinds of fungicide of the invention, expands fungicidal spectrum；
3, two kinds of effective ingredient mechanism of action of composition pesticide provided by the invention are different, can overcome long-term list
One the shortcomings that easy ting produce resistance using medicament, extends the service life of medicament, have to the comprehensive treatment of rice fungal disease
