Description
Technical field
The present invention relates to technical field of pesticide compounding, and in particular to one kind contains prothioconazoles, isotianil, fluorine thiophene
Efficient, the less toxic compounding suspension seed-coating agent and the preparation method and application thereof of azoles pyrrole ethyl ketone.
Background technique
Suspension seed-coating agent (Flowable Concentrates for Seed Coating, FS) refer to not soluble in water or
The effective component (solid raw medicine, compound fertilizer, plant growth regulator, microelement) for being insoluble in water is subject to auxiliary aid, such as
After wetting agent, dispersing agent, warning coloration, film forming agent etc. pass through soybean dietary fiber, effective component is 0.5 μm -5 μm with partial size
Particle form is evenly dispersed in water, the multinomial coarse dispersion system of formation.Its difference from suspending agent is that preparation can be direct
It is coated on the surface of the seed, being formed has some strength and permeability protective film, for preventing and treating seedling stage diseases and pests and subterranean pest-insect
Harm.
Isotianil (Isotianil) is the isothiazole class fungicide that Bayer and Sumitomo Chemical are researched and developed jointly, is mainly used for
Rice blast is prevented and treated, it is characterized in that it does not generate direct antibacterial action to pathogen, but by excitation rice itself to rice
The natural immunology defense of seasonal febrile diseases achievees the purpose that disease-resistant.Isotianil is first low utilization rate for having induction of resistance effect
Active constituent example.Rice blast is the rice disease for causing maximum economic loss in the world, and only few in number at present is several
Pesticidal products are approved for prevention and treatment rice blast.
Prothioconazoles are New-type wide-spectrum triazole thioketone demethylation inhibitors fungicide.It is mainly used for preventing and treating wheat, big
Multiple diseases on wheat, rape, peanut, rice, legume crop, beet and field vegetables etc..Almost have to all wheat diseases
There is fine control efficiency, such as the powdery mildew on wheat and barley, banded sclerotial blight, leaf spot, rust, net blotch, moire disease；It can also
Prevent and treat the soil-borne disease of rape and peanut, the disease such as sclerotiniose, southern blight and main leaf, such as gray mold, black spot, foxiness
Disease, balck shank and rust etc..
Fluorine thiazole pyrrole ethyl ketone is the new with completely new chemical structure and action target of the research and development of DuPont Corporation 2007
Type fungicide.Studies have shown that fluorine thiazole pyrrole ethyl ketone forms the mycelia extension of Pseudoperonospora cubensis, sporangiophore, sporangium generates, travelling
Spore travelling, the spore that stops are sprouted and germ tube elongation all has excellent inhibiting effect, which can inhibit the bacterium of Pseudoperonospora cubensis
Silk growth, and the highly energy-consumings stages such as zoospore travelling, the release of zoospore and the spore that stops sprouting are influenced with apparent,
Illustrate that the medicament can be applied in each stage that pathogen invades people.
The advantages of suspension seed-coating agent, is: (1) without dust, can reduce harm of the dust to user and the producer；(2) with water
For matrix, harm of the organic solvent to environment and crop is reduced；(3) there is good film forming, seed smoothness is high after coating,
Expulsion rate is low, facilitates sowing；(4) partial size is smaller, and coating is more evenly;(5) function diversification can prevent and treat a variety of pest and disease damages together；
(6) lasting period is long.Medicament on seed is generally not easy to spread into soil, but is gradually absorbed by plants and plays a role.
Present inventor pass through a large amount of lab screening and field control effectiveness test, discovery prothioconazoles, isotianil,
Fluorine thiazole pyrrole ethyl ketone composition can play the double effects of sterilization and strong seedling, and than pesticide phase is used alone after three's compounding
Than no matter all increasing significantly in terms of strong Miao Xiaoguo, bactericidal effect, use cost can be reduced, to crop safety height.
Summary of the invention
In order to solve the above technical problems in background technology, the present invention provides a kind of wide sterilization spectrum, effectively at
Point usage amount is low and can effectively slow down and administer the sterilizing disease-preventing suspension seed-coating agent of resistance generation and application.
In order to solve the above technical problems, the present invention adopts the following technical scheme: a kind of suspension seed-coating agent, which is characterized in that
Effective component includes prothioconazoles, isotianil, fluorine thiazole pyrrole ethyl ketone.
Further, with the isotianil of bactericidal insecticidal activity, the mass ratio of prothioconazoles and fluorine thiazole pyrrole ethyl ketone is
1-30:10-1:1-10.
Further, the effective component accounts for the 10%-45% of suspension seed-coating agent gross mass, preferably 15%-40%.
Specifically, the auxiliary agent includes wetting agent, dispersing agent, safener etc..When necessary, it also to be added in auxiliary agent anti-
Mould dose, antifreeze, defoaming agent, thickener, film forming agent, the auxiliary agents such as pH adjusting agent.
Further, the dosage form of suspension seed-coating agent of the invention can be suspension seed-coating agent.
Compared with prior art, suspension seed-coating agent of the invention have the beneficial effect that present inventor to isotianil,
Prothioconazoles, fluorine thiazole pyrrole ethyl ketone are furtherd investigate, and discovery prothioconazoles, isotianil, fluorine thiazole pyrrole ethyl ketone are compounded
Combination has apparent synergistic effect, and there are suspension seed-coating agent performance characteristics mainly to have: one is that it does not generate directly pathogen
The antibacterial action connect, but the natural immunology defense of rice blast is achieved the purpose that disease-resistant by excitation rice itself.Two or three kinds
Effective component mutually acts synergistically；Three's compounding makes medicament have absorbability, and therapeutic and protective effects can not only protect plant
It can also healthy and strong plant；Three's compounding expands prevention spectrum, can not only prevent and treat Oomycete germ, moreover it is possible to prevent and treat other nosomycosises
Bacterium.
