Description
Technical field
The present invention relates to composition pesticide and its application fields, specifically with prothioconazoles, fludioxonil and clothianidin
For the ternary complex of effective active composition compounding, it is mainly used in the seed Dressing of crops.
Background technique
Prothioconazoles (Prothioconazole): prothioconazoles are New-type wide-spectrum triazole thioketone demethylation inhibitors
Fungicide.It is mainly used for preventing and treating a variety of on wheat, barley, rape, peanut, rice, legume crop, beet and field vegetables etc.
Disease.Almost to all wheat diseases have fine control efficiency, as on wheat and barley powdery mildew, banded sclerotial blight, leaf spot,
Rust, net blotch, moire disease etc.；The soil-borne disease that rape and peanut can also be prevented and treated, such as sclerotiniose, southern blight and main leaf
Disease, such as gray mold, black spot, brown spot, balck shank and rust.
Fludioxonil (Fludioxonil): for non-interior suction benzene pyroles contact killing type fungicide, pass through inhibition glucose phosphorylated
Related transfer, and inhibit the growth of fungal mycelium, germ death is eventually led to, the mechanism of action is unique, with existing fungicide
No interactions resistance.High-efficiency broad spectrum passes caused by many pathogens such as sac fungus, basidiomycetes, Fungi Imperfecti kinds and soil-borne disease has
Extraordinary preventive effect.
Clothianidin (Clothianidin): belonging to second generation nicotinic insecticide, and the mechanism of action is to act on insect nerve
NAChR outstanding afterwards.Mainly there is preferable control efficiency to the sucking pest on crops.
In modern agricultural production, due to the surface of the seed or inside is carried disease germs, pest is caused harm in fungus in soil or soil, kind
After planting usually there is sick seedling in son, lacks nest, phenomenon of being short of seedling caused by weak seedling and insect pest etc., causes greatly to damage to agricultural production
It loses.Seed chemicals treatment can not only prevent and treat crops soil biography, seed-borne disease and subterranean pest-insect, but also to plant seedling on crop field
The pest and disease damage that phase occurs also has good prevention effect.
The present inventor is effective active composition ternary built formula in further investigation prothioconazoles, fludioxonil and clothianidin
In the process, surprisingly the ternary recompounded composite of prothioconazoles, fludioxonil and clothianidin is to crop seeds, especially
It is that can significantly improve the germination percentage of rice paddy seed after rice paddy seed Dressing, mitigate the hair of the pest and disease damages such as bakanae disease, thrips
Raw, increase rice yield.
Summary of the invention
The present invention is intended to provide a kind of insecticidal and bactericidal composition for seed treatment, the insecticidal and bactericidal composition can be used for
After crop seeds Dressing, especially rice paddy seed Dressing, the germination percentage of rice paddy seed can be significantly improved, mitigates and dislikes
The generation of the pest and disease damages such as seedling diseases, thrips increases rice yield.
Technical solution of the present invention: to achieve the above object, the present invention provides a kind of pesticide-germicide for seed treatment
Composition, effective component are made of prothioconazoles, fludioxonil, clothianidin, and prothioconazoles, fludioxonil, clothianidin are in the composition
Mass ratio be respectively as follows: 1-30%, 0.1-10%, 1-55%, other components are nonactive additive, mainly include
