Bactericidal composition containing metconazole
Technical field
It is more particularly to a kind of that there is the bactericidal composition for improving performance, tool the invention belongs to agriculture plant protection field
Say it is to be related to a kind of bactericidal composition for including metconazole body.
Background technology
Metconazole (metconazole) is a kind of bactericide action character:The medicine is a kind of new, wide-spectrum bactericide, right
Fungal disease has preventive and therapeutic action.The mechanism of action presses down with C-14 demethylations enzyme in feature ergosterol biosynthesis
Preparation.Although the mechanism of action is as other triazole bactericidal agents, then difference is larger for activity profile.Two kinds of isomers have sterilization
Activity, but Cis activity is higher than trans.The antifungal spectrum of metconazole widely, and activity it is splendid.The administration pair of metconazole field
Cereal crops septoria musiva, fusarium and handle rest fungus, which plant disease, excellent effect.Metconazole compared with traditional biocide agent, dosage it is extremely low and
Prevent and treat the sick scope of cereal plant but very wide.
Fluoxastrobin (Fluoxastrobin) is a kind of wide-spectrum bactericide, and various crop is drawn by sac fungus and Fungi Imperfecti
The disease risen has obvious preventive effect, and the mechanism of action is with feature with Fluoxastrobin and other methoxy acrylic bactericides one
Sample, the mechanism of action of fluoxastrobin is also mitochondrial respiratory inhibitor, i.e., by between cytochrome b and C1 electro transfer suppress
Mitochondrial breathing.The bactericide for acting on mitochondrial respiratory is more.Fluoxastrobin application optimum period, is wide, no matter early in fungal infection
Phase such as spore germination, germ tube growth and intrusion leaf portion, or can provide extraordinary protection and treatment in growth period of hypha
Effect;But spore germination and initial stage are infected most effective.Because of the excellent systemic activity having, it can be rapidly absorbed, and energy
Equably transmitted in leaf portion to top, therefore with the good resistance of rainwater washing against ability of root.
Foliage disease such as leaf blight, leaf rust, the grain husk that ZEN 90160 (Picoxystrobin) is mainly used in preventing and treating wheat class are withered
Disease, brown spot, powdery mildew etc., compared with other existing methoxy acrylic bactericides, to wheat leaf blessing disease, net blotch and
Moire disease has stronger therapeutic effect.Methoxy acrylic bactericide is a class low toxicity, efficient, wide spectrum, absorbability sterilization
Agent, almost to all fungies (Oomycete, Phycomycetes, Ascomycetes and deuteromycetes) disease for example powdery mildew, rust, glume blight,
Net blotch, downy mildew, rice blast etc. have good activity, and can effectively prevent and treat the disease that other bactericide are produced with resistance
Opportunistic pathogen series, the bacterium of resistance is produced to 14- demethylations enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine and benzimidazole
Strain is effectively.With protecting, treat, root out, osmosis, be world pesticide circle after triazole type the features such as without carcinogenic and mutagenesis
The extremely potential pesticide species of another class after bactericide.
SSF 126 (metominostrobin) mechanism of action mitochondrial respiratory inhibitor, i.e., by carefully run pigment b and
Electro transfer suppresses mitochondrial breathing between C1.Preventing and treating is to 14- demethylations enzyme inhibitor, benzamides, dicarboxylic dihydrazides amine
The bacterial strain for producing resistance with benzimidazole is effective.With protecting, treat, root out, permeating, systemic activity.
Actual agricultural chemicals experience have shown that, repeat and single-minded apply a kind of reactive compound to prevent and treat harmful fungoid very
It will cause the fast selective of fungal bacterial strain in the case of many, it is current usual for the danger of reduction refractory fungal bacterial strain selectivity
Harmful fungoid is prevented and treated using the mixture of different activities compound.By the way that the reactive compound with the different mechanisms of action is entered
Row combination, can delaying drug resistance generation, reduction amount of application, reduction cost accounting.
The content of the invention
The technical problem to be solved in the present invention is:For bactericide resistance and pedo relict problem in actual applications,
The bactericide for filtering out two kinds of different sterilizing mechanismses is compounded, to improve bactericidal agent for preventing and treating effect, and delaying drug resistance is produced, reduction
Amount of application, reduces cost accounting.
In order to solve the above technical problems, the invention provides a kind of bactericidal composition, said composition comprising two kinds effectively into
Divide A and B, active component A is metconazole, it is characterised in that described composition includes two kinds of active components of A and B, wherein activity
Component A is metconazole, and active component B is selected from methoxy acrylic bactericide fluoxastrobin, ZEN 90160, SSF 126
In one kind.
Inventor is found by experiment that composition of the invention is to be used to prevent and treat controlling fungal diseases of crop and phytosis
Evil, sterilization synergy is obvious, it is often more important that amount of application is reduced, and reduces use cost.Compound knot containing component A Yu component B
Structure type is different, and mechanism of action is different, and both can expand fungicidal spectrum at compounding, and can delay pathogen to a certain extent
No interactions resistance between the generation of resistance and development speed, and component A and component B.
It is a further object to provide the preparation method comprising two kinds of effective constituents As and B bactericidal compositions and
Agriculture field prevents and treats the application of corps diseases.
In above-mentioned bactericidal composition, the weight ratio between component A and component the B component of weight two is 1:30~30:1, it is excellent
Select 1:20~30:1 or 1:30~20:1, more preferably 1:20~20:1, to make the drug effect synergistic effect between two components more notable,
Weight ratio between component A and component the B component of weight two can further be optimized to 1:10~10:1.
In a kind of technical scheme, bactericidal composition of the invention be by the active component of 4~85% parts by weight with 96~
The insecticides adjuvant composition of 15% parts by weight.
The invention provides (be selected from the phonetic bacterium of methoxy acrylic bactericide fluorine comprising component A (metconazole) and component B
One kind in ester, ZEN 90160, SSF 126) bactericidal composition in controlling plant diseases (particularly corps diseases)
Purposes, the particularly disease in terms of powdery mildew, rust is prevented and treated, such as wheat powdery mildew, wheat rust poison, rice blast
Or in terms of rice sheath blight disease.
The composition of the present invention is aided with acceptable auxiliary material on agricultural chemicals with active component and any of suitable agricultural use is made

Concentration EC50 during method calculates virulence equation and suppressed, the toxicity index level co-toxicity coefficient (CTC) of medicament is calculated according to the abundant methods of Sun Yun.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) * 100
A percentage composition+B medicament toxicity index * mixtures in theoretical toxicity index (TTI)=A medicament toxicity index * mixtures
Middle B percentage composition
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] * 100
CTC≤80, composition shows as antagonism, 80 < CTC < 120, and composition shows as summation action, and CTC >=
120, composition shows as synergistic effect.
