Abstract
The invention relates to a seed treating agent composition which is composited by fipronil, azoxystrobin and fludioxonil as active components. The treating agent composition can effectively prevent diseases, such as a rice bakanae disease and sheath blight, wheat sharp eyespot, a cotton blight disease, peanut root rot, bean root rot, and corn stalk rot, and no harmful residues to influence seed germination, seedling development, plant growth and a product are remained.
Description
Technical field
The present invention relates to a kind of mixed pesticide technology, be specifically related to a kind of by fluorine worm nitrile, Fluoxastrobin, three kinds of active components of fludioxonil and the composite desinsection that forms of other agricultural agent/sterilization seed treatment.
Technical background
Crops easy infection in plantation and process of growth infects all kinds of diseases that cause by seed and soil, for example bakanae disease of rice and banded sclerotial blight, wheat sharp eyespot, cotton seedling blight, peanut root rot, root rot, corn base rot disease etc.Seed-borne fungi is diseases induced first dip-dye source, and it can cause infecting, take place, spread and endangering of disease in the season of growth; And after seed-borne disease takes place, growth, growth, the yield and quality of crop all had very big influence.
Carry out seed treatment before the present stage people are employed in usually and broadcast and eliminate seed-borne disease, so that seed and seedling exempt from the harm of soil-borne disease and insect.Seed treatment specifically can be divided into inorganic and organic, volatile or nonvolatile, interior suction or non-interior suction, after preparation, uses with pulvis, water solube powder, wetting powder, emulsion, liquor or suspending agent.The current product category that is used for seed treatment is a lot, defending of for example having that the U.S. favourable incoming road chemical industrial company the develops good Nian Dong that sharp strength is special, U.S. Fu Meishi company develops that good fortune, French Rhone-Poulenc develop etc.In disease preventing and treating, a good seed treatment also should not stay any hazard residue thing that influences seed sprouting, seedling development, plant strain growth and product.Current, seek the research focus that the seed treatment composition of economical and efficient more remains pesticide field.
Summary of the invention
The object of the present invention is to provide a kind of by fluorine worm nitrile, Fluoxastrobin and fludioxonil as the composite insecticide/bactericides seed treatment that forms of active component.
This inorganic agent can effectively be prevented and treated by seed and soil and infect disease and soil insect such as grubs etc. such as propagating the bakanae disease of rice/banded sclerotial blight cause, wheat sharp eyespot, cotton seedling blight, peanut root rot, root rot, corn base rot disease, and does not stay any hazard residue thing that influences seed sprouting, seedling development, plant strain growth and product.
Concrete technical scheme of the present invention is following:
A kind of seed treatment composition that contains fluorine worm nitrile by weight percentage, comprises following component:
As active component, the percentage by weight of fluorine worm nitrile is preferably 20% in the above-mentioned composition, and the percentage by weight of Fluoxastrobin is preferably 10%, and the percentage by weight of fludioxonil is preferably 8%.
Said dispersant is selected from least a in dispersing agent MF, alkyl naphthalene formaldehyde condensate sulfonates, polycarboxylate, calcium lignosulfonate, the sodium lignin sulfonate.
Said wetting agent is selected from least a in lauryl sodium sulfate, neopelex, alkylnaphthalene sulfonate, alkylphenol-polyethenoxy base ether formaldehyde condensation products sulphate, APES phosphate, phenethyl phenol polyethenoxy base ether phosphate, lauryl alcohol polyethylene glycol oxide base ether sodium sulfate, the APES formaldehyde condensation products succinate sodium sulfonate.
Said adhesive is selected from least a in alkylaryl polyoxy ethyl ether, fatty alcohol polyoxy ethyl ether, alkylnaphthalene sulfonate and the polyvinyl alcohol.
Said filler is selected from least a in clay, potter's clay, kaolin, diatomite, the pyrophyllite.
Through in composition, adding water, filler or the water of surplus and the combination of filler, agent composition of the present invention can be processed as suspension seed-coating agent, wetting powder or water dispersible granules respectively.
Seed treatment composition according to the invention can be prepared from through this area routine and known way, active component and other auxiliary agent is mixed get final product.For example; Prepare above-mentioned wetting powder and can adopt following steps: the method with machinery or comminution by gas stream is machined to the 800-1000 order with the former medicine fluorine of solid worm nitrile, Fluoxastrobin and fludioxonil; Fully mix with dispersant, wetting agent, adhesive and filler then, can obtain the wetting powder finished product.
The seed treatment composition of the application of the invention; Can effectively prevent and treat by seed and soil and infect disease and soil insect such as grubs etc. such as propagating the bakanae disease of rice cause and banded sclerotial blight, wheat sharp eyespot, cotton seedling blight, peanut root rot, root rot, corn sickle base rot disease, and not stay any hazard residue thing that influences seed sprouting, seedling development, plant strain growth and product.Moreover, through the composite use of three kinds of active components, can play synergistic effect between three kinds of active components, composition has been obtained excellent more seed treatment effect, obviously is superior to single agent kind.
