Description
Technical field
It is with fluxapyroxad and Boscalid (or thifluzamide) is to have the present invention relates to a kind of agricultural bactericidal composition
Ingredient is imitated, for preventing and treating powdery mildew of cucumber, powdery mildew of strawberry, gray mold of cucumber, grey mould fruit rot of strawberry, rice sheath blight disease.
Background technique
The resistance problem of agricultural disease is a global problem, is always the emphasis class of agricultural science and technology worker concern
Topic.With the continuity year in year out of disease chemical prevention, the increase of Pesticide use amount and not scientifical use pesticide, germ
Resistance is got worse, and the germ type for generating resistance is increasing.Meanwhile high-intensitive use pesticide, lead to agricultural product pesticide
Exceeded, environmental pollution and the increase of peasant's drug cost etc. are remained, agricultural sustainable development is unfavorable for.Therefore, research and development efficiently,
Low toxicity, environmentally friendly bactericide agricultural chemicals have positive effect to agricultural sustainable development.
Fluxapyroxad, English name: fluxapyroxad is acid amide fungicides, main by inhibiting mitochondria amber
Amber acid esters dehydrogenase hinders tricarboxylic acid cycle, lacks amino acid, sugar, energy reduction, interferes the division and growth of cell, have
There are protection and therapeutic effect.It is efficient to gray mold, the powdery mildew of gourd, fruit and vegetable class crop, also there is higher work to fruit tree anthracnose
Property.
Boscalid, English name: boscalid, Boscalid is consistent with the fluxapyroxad mechanism of action, to melon, careless
The crop powdery mildews such as the certain kind of berries and gray mold are efficient.
Thifluzamide, English name: thifluzamide has very strong Uptake and translocation performance, can be with foliar spray, seed
The modes such as processing, soil treatment are applied, efficient to rice sheath blight disease, peanut sclerotium rolfsii.
The mixture of different pesticide species is the common methods for preventing and treating agricultural pest.It is screened, is filtered out by formulation of pesticide
Reasonable formula, can effectively improve practical control efficiency, reduce dosage, reduce cost, delay the generation of pest and disease damage drug resistance,
It is an important means of comprehensive agricultural management.The present inventor carries out the recipe determination of succinate dehydrogenase inhibitors class fungicide
Further investigation, it is found that it has apparent synergistic effect to a variety of fungies in a certain mix proportion range, after further study, complete
At the present invention.
The composition and application of fluxapyroxad and Boscalid (or thifluzamide) there is no report at present.
Summary of the invention
The technical problem to be solved by the present invention is to provide one kind efficiently, low toxicity and lasting period are long, can effectively prevent agriculture fungi
One kind of venereal disease evil contains the agricultural bactericidal composition of fluxapyroxad and Boscalid (or thifluzamide).
To solve the above problems, the technical scheme adopted by the invention is that: a kind of agricultural bactericidal composition, comprising effectively at
Divide A and B and insecticides adjuvant, effective constituents A is fluxapyroxad, and effective component B is in Boscalid or thifluzamide
It is a kind of；Effective constituents A and the weight ratio of B are 1:10~10:1, the weight summation of effective constituents A and B weight hundred in the composition
Divide than being 1%~90%.
According to the actual application, the present composition according to methods well known to those skilled in the art, can be prepared as
One of aqueous emulsion, microemulsion, suspending agent, wettable powder, water dispersible granules.
Auxiliary agent needed for the agricultural bactericidal composition also contains preparation pesticidal preparations, auxiliary agent are solvents, emulsifier, are total to
One of emulsifier, wetting agent, stabilizer, dispersing agent, thickener, pH adjusting agent, defoaming agent, antifreezing agent, filler etc. are several
The mixing of kind, is known substance, is common various auxiliary agents in pesticidal preparations, can be varied according to different situations, and
It is not particularly limited.
The agricultural bactericidal composition, for preventing and treating cucumber, powdery mildew of strawberry, rice sheath blight disease.
Bactericidal composition provided by the invention generallys use spray method use, also can according to need using agriculturally
Other of application use technology.
The method have the advantages that:
1, bactericidal composition provided by the invention shows apparent synergy or summation action within a certain ratio range,
Composition is significantly improved to the control efficiency of germ than single dose, reduces the dosage of pesticide, reduces times for spraying,
Drug cost is reduced, reduces pesticide to the adverse effect of ecological environment.
2, bactericidal composition provided by the invention, the combination of two kinds of effective ingredients expand fungicidal spectrum, a drug
It solves the problems, such as multiple diseases, compensates for defects and limitations when single dose uses.
3, bactericidal composition provided by the invention, drug effect play rapidly, and the lasting period is long, and use cost is low, easy to use, save
Shi Shengli, popularization and application have huge economic benefit and social benefit.
