Abstract
The invention provides a kind of microbicide compositions, said composition comprises two kinds of effective constituents A and B, and active component A is to have the structural compounds of formula I, and active component B is SAN-619F, and the weight ratio between two components is 10～1:1～30.Present invention also offers the Preparation method and use of said composition.Result of the test shows, the above-mentioned bactericidal composition potentiation that the present invention provides is obvious, it is often more important that amount of application reduces, and use cost reduces.This bactericidal composition can effectively prevent and treat some specific antibacterial or fungal disease of crop.By the antibacterial of different mechanism of action and model of action is compounded, for expanding fungicidal spectrum and delaying the aspects such as fungus, bacterial resistance and raising prevention effect to have well effect.
Description
Technical field
The invention belongs to agriculture plant protection field, particularly relate to a kind of bactericidal composition having and improving performance, tool
Say body and relate to a kind of bactericidal composition comprising BIT class and SAN-619F.
Background technology
BIT compounds is a kind of novel, wide-spectrum bactericide, is mainly used in preventing and treating and treatment Cereal
The various bacteria such as crop, veterinary antibiotics, fungal disease.Its bactericidal action mechanism, mainly includes destroying pathogenic bacteria nucleus knot
Structure so that it is lose cardia and exhaustion is dead and the metabolism of interference pathogenic bacteria cell so that it is physiologic derangement, ultimately results in dead
Die two aspects.Using can effectively protect plant not infected by pathogen at disease early period of origination, disease takes the circumstances into consideration to increase after occurring
Dosage can substantially control spreading of pathogenic bacteria, thus reaches protection and the dual function rooted out.
SAN-619F (cyproconazole) belongs to triazole bactericidal agent, has prevention, treatment, systemic action.It is applicable to little
The plants such as wheat, Fructus Hordei Vulgaris, Herba bromi japonici, Semen Maydis, Sorghum vulgare Pers., Radix Betae, Fructus Mali pumilae, pears, can effectively prevent and treat Erysiphe, Puccinia, beak genus,
The disease that nuclear cavity Pseudomonas and Septoria bacterium etc. cause.(ergosterol biology closes its bactericidal action feature steroid demethylation
Become) inhibitor, can be partially absorbed and mainly shift to top by plant is vegetative rapidly.
Actual pesticide experience have shown that, repeats and single-minded one reactive compound of using is to prevent and treat harmful fungoid very
The fast selective of fungal bacterial strain will be caused in the case of Duo, the most dangerous, the most generally for reducing refractory fungal bacterial strain
The mixture using different activities compound prevents and treats harmful fungoid.By the reactive compound with the different mechanism of action is entered
Row combination, delaying drug resistance can produce, reduces amount of application, reduce cost accounting.
Summary of the invention
It is an object of the invention to, for antibacterial resistance in actual applications and pedo relict problem, filter out difference and kill
The antibacterial of bacterium principle compounds, and obtains new a kind of microbicide compositions, to improve bactericidal agent for preventing and treating effect, delaying drug resistance
Produce, reduce amount of application, reduce cost accounting.
It is a further object to provide comprise two kinds of effective constituents A and the preparation method of B bactericidal composition and
The application of agriculture field preventing and treating corps diseases.
The purpose of the present invention can be reached by following measures:
A kind of microbicide compositions with potentiation, said composition comprises two kinds of active components of A and B, wherein activity
Component A is to have the structural compounds of formula I, and active component B is SAN-619F.
In formula I, R is selected from H or C1～C8Alkyl.
C in the present invention1～C8Alkyl refers to the straight or branched alkyl containing 1 to 8 carbon atom, and it includes C1Alkyl
(such as methyl), C2Alkyl (such as ethyl), C3Alkyl (such as n-pro-pyl, isopropyl), C4Alkyl (as normal-butyl, isobutyl group, the tert-butyl group,

Method calculates concentration EC50 in virulence equation and suppression, calculates toxicity index level co-toxicity coefficient (CTC) of medicament according to the abundant method of Sun Yun.
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) * 100
Percentage composition+B medicament toxicity index * the mixture of A in theoretical toxicity index (TTI)=A medicament toxicity index * mixture
The percentage composition of middle B
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)] * 100
CTC≤80, compositions shows as antagonism, 80 ＜ CTC ＜ 120, and compositions shows as summation action, CTC >=
120, compositions shows as potentiation.
