Description

Seed treatment compositions containing fludioxonil and Prochloraz and purposes

Technical field

The invention belongs to seed treatment fields, and in particular to be a kind of to contain fludioxonil, Prochloraz and fluorine pyrrole furans The method of the seed treatment compositions of ketone and its pest control and/or disease for resisting.

Background technology

It is that prevention soil passes and plant one of the effective way of borne disease, seed treatment to seed treatment using seed treatment Agent can pass and plant borne disease and raising by slow release medicine component to reach prevention soil in the soil because of its film forming characteristics The purpose of percentage of seedgermination.Therefore, solve the problems, such as that soil passes and kind borne disease has become work from source using seed treatment The important technology that object high yield increases income.

Pill pelletizing coating is to be coated the agricultural use new technology to come into operation later after film, due to the kind of granule and particle Ziren work and mechanical planting are more difficult, and seed is especially broadcast live and causes seed serious waste phenomenon, seed-pelleting coating can Solve the problems, such as this;Secondly as small-sized seed, especially particle seed individual are small, poor resistance uses fungicide or addition Fertilizer carries out film coating and is easy to cause poisoning, and pill pelleting seed coating slows down medicament pair due to the shielding action of obducens The poisoning that seed is generated with seedling;In addition, the chemical substance for promoting root and growth of seedling can be added in Parcel of seed agent, plays and carry The effect of high Seedling Quality, thus the research of pill pelletizing coating is valued by people, currently, the bonding that pill pelletizing coating uses Agent mainly has the water-soluble binders such as starch, polyvinyl alcohol, polyethylene glycol, sodium alginate, Arabic gum, powder mainly to have diatom Soil, kaolin, talcum powder, calcium carbonate, mud calcium soil etc., the coating method that pill pelletizing coating uses for:Seed is first put into coating In container, to the surface of the seed spray adhesive solution while container rotates, powder body material is then put into, is allowed to and seed knot Altogether, aforesaid operations are repeated, until the grain size of pelleted seed reaches the thickness of anticipation.

Fludioxonil, English common name Fludioxonil belong to phenylamide, for efficient, low toxicity, low-residual, lasting period Long, insecticide-applying way diversification, protection and the excellent wide spectrum systemic fungicide of therapeutic effect can make cauline leaf process, at seed Reason and soil treatment, have significant control effect to crop disease caused by downy mildew, phytophthora, pythium spp etc..

Prochloraz, English common name Prochloraz are worked by inhibiting the biosynthesis of sterol, and no interior suction is made With splendid for multiple diseases preventive effect caused by sac fungus and Fungi Imperfecti.It is conventional to use prevention vegetables anthracnose, leaf spot, bacterium Core disease etc..

Fluorine pyrrole furanone, English common name flupyradifurone;Developing code name is:BYI02960;Trade name: Sivanto, Sivanto Prime etc..Its IUPAC is entitled:4-[(6- chloro-3-pyridyls ylmethyl) (2,2- bis-fluoro ethyls) An Ji ] Furans -2 (5H) -one;CAS accession number:[951659-40-8];Relative molecular mass:288.7;Molecular formula: C12H11ClF2N2O2.Its chemical structural formula is:

Fluorine pyrrole furanone had not only been accomplished quick, efficient but also environmentally friendly when preventing sucking pest, and toxicity is low, Especially to honeybee safety.

In the entire growth cycle of crops, it is not only faced with insect pest, the pollution of some pathogens also can be to crop Growth impacts, and especially seed is sprouted the stage, and it is an extremely important and effective guarantor that seed treatment is carried out before sowing Shield measure.Seed pelleting can make medicament form one layer of more firm film in the surface of the seed, air-and water-permeable but also can play The effect of diseases prevention insect prevention, thus favored deeply by peasant and researcher.

Invention content

In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide it is a kind of can diseases prevention but also desinsection seed treatment Composition, active constituent action compensating in the seed treatment compositions, can not only reach a drug, prevent a variety of disease pests Harmful purpose, and can have certain synergistic function between each other with active constituent, it reduces pesticide activity component and uses Amount improves control effect.

Another object of the present invention is to provide the application of the seed treatment compositions, the seed treatment compositions are outstanding It is suitable for the prevention insect pests such as multiple kinds of crops especially vegetable aphid, flea beetle, and for prevent crops vegetables powdery mildew, Gray mold, leaf blight, sclerotiniose, damping-off etc..

Another object of the present invention, which also resides in, provides a kind of method for handling seed, and including will be at the seed of the present invention Manage composition and seed and/or the physical contact between media of sowing seed.

Another object of the present invention, which also resides in, provides the purposes that the seed treatment compositions are used to prepare pill pelleting seed.

In order to achieve the above object, the present invention adopts the following technical scheme that:
