Description
Technical field
The present invention relates to pesticide sterilizing composite and application thereof, specifically a kind of with benzothiostrobin and succinic acid
Dehydrogenase inhibitor series bactericidal agent is the binary complex of active component, is mainly used in the preventing and treating of powdery mildew on crops.
Background technology
Benzothiostrobin (benzothiostrobin), belongs to methoxy acrylic bactericide, and the mechanism of action is line grain
Body respiratory chain cytochrome b c1 complex inhibitor, has a good safety to beneficial organism and crop, low toxicity and to environment friend
Good.Benzothiostrobin may be used for the preventing and treating of multiple diseases, particularly powdery mildew of cucumber and cucumber downy mildew is shown excellence
Preventive effect.
Succinate dehydrogenase inhibitors (SDHI) series bactericidal agent is after methoxy acrylic bactericide, develops again
There is a class disinfectant use in agriculture of novel mechanism of action, mechanism of action mainly suppression pathogen succinic dehydrogenase activity, from
And disturb its Repiration, its effect is special, strong drug action, persistent, obvious effect of increasing production.Benzo alkene fluorine bacterium azoles
(benzovindiflupyr) it is succinate dehydrogenase inhibitors (SDHI) class sterilizes with isopyrazam (isopyrazam)
Agent.
Pesticide individually long-time uses continuously and easily produces resistance risk and consumption increases risk, so increase cost and
Carrying capacity of environment, and the compositions with notable synergistic function is filtered out by agriculture chemical compounding, Pesticide use can not only be reduced
Amount, the use cost that reduces, minimizing resistance risk, moreover it is possible to reduce potential environmental risk.
The mixture combination of benzothiostrobin with succinate dehydrogenase inhibitors (SDHI) series bactericidal agent is carried out by the present inventor
Further investigation, on the basis of substantial amounts of test, finds benzothiostrobin and succinate dehydrogenase inhibitors (SDHI) series bactericidal agent
Combine in certain amount ranges, preventing and treating crop powdery mildew performance synergistic function, pesticide can be given by Technology
Dosage form.After further study, the present invention is completed.
Summary of the invention
It is desirable to provide a kind of containing benzothiostrobin with the compositions of succinate dehydrogenase inhibitors series bactericidal agent, should
Bactericidal composition has significant synergistic function, to multiple diseases on crops, especially has excellence to powdery mildew
Prevention effect.
Technical scheme: for achieving the above object, the present invention provides a kind of and takes off containing benzothiostrobin and succinic acid
The compositions of hydrogen enzyme inhibitor series bactericidal agent, its effective ingredient is benzothiostrobin and succinate dehydrogenase inhibitors series bactericidal agent,
Succinate dehydrogenase inhibitors series bactericidal agent one in benzo alkene fluorine bacterium azoles or isopyrazam, benzothiostrobin and succinum
The weight ratio of dehydrogenase inhibitor series bactericidal agent is 20:1～1:10, and preferred weight ratio is 10:1～1:4；Benzothiostrobin and amber
The weight summation of amber dehydrogenase inhibitor series bactericidal agent percentage by weight in the composition is 1%～85%.
In the present composition, in addition to the active ingredient (s, solvent, cosolvent, emulsifying agent, dispersant, wetting agent, increasing are also included
Thick dose, antifreezing agent, cyst material, pH adjusting agent, defoamer, disintegrating agent, stabilizer, penetrating agent, diffusant, preservative, potentiation
The pesticide such as agent, poisoning palliative, binding agent, density adjuster and filler allow use and acceptable auxiliary element, all
Being conventional in pesticidal preparations or the composition of permission use, be not particularly limited, concrete composition and consumption pass through according to recipe requirements
Test determines.
The present composition can be prepared as the multiple application forms being suitable in agricultural production using, and reasonable dosage form has
Microcapsule suspending agent, suspending agent, aqueous emulsion, microemulsion, water dispersible granules, wettable powder and ultra low volume liquids.
The production technology of the various application forms of described compositions all belongs to existing known technology, does not repeats them here.
Compositions described in the invention, can provide with finished product preparation form, and i.e. in compositions, each material is the most blended, group
The composition of compound can also provide by unit dose form, directly mixes in bucket or tank, be then diluted to desired concn before using.
The compositions of the present invention, is used for preventing and treating crop powdery mildew.
Compared with prior art, it is an advantage of the current invention that:
1, benzothiostrobin and succinate dehydrogenase inhibitors series bactericidal agent compound and have significant synergistic function, than
Single dose is used alone and significantly improves the prevention effect of disease on crops.
2, benzothiostrobin and two kinds of active component of succinate dehydrogenase inhibitors series bactericidal agent compound, and decrease Pesticide use
Amount, reduces use cost, alleviates the pollution to environment.
3, benzothiostrobin and two kinds of active component of succinate dehydrogenase inhibitors series bactericidal agent compound, the mechanism of action the most not phase
With, action site increases, and has delayed the drug-fast generation of pathogen, has added the service life of pesticide.
