Etc. disease.Not only have and well protect, treat and root out activity, and there is interior suction and preferably residual activity..
The difficulty of prevention and cure of phytopathogen is increasing at present, on the one hand, along with the change of pattern of farming, melon fruits and vegetables etc.
Industrial crops cultivated area progressively expands, and disease occurrence degree, generation quantity all increase, and in preventing and treating, difficulty strengthens；
On the other hand, the resistance of pathogen rises under lasting medicament selection pressure year by year, and the prevention effect of single dose is had a greatly reduced quality,
Control of plant disease is faced with significant challenge.
Summary of the invention:
It is an object of the invention to provide a kind of applied widely, low cost for above-mentioned technical problem, effective containing biphenyl
Pyrrole bacterium amine and the plant bactericidal composition of epoxiconazole.
It is a still further object of the present invention to provide this bactericidal composition and cause the application on fungal disease at preventing and treating plant epiphyte,
Especially in the purposes prevented and treated on the fungal diseases such as powdery mildew, rust, downy mildew, damping-off, eyeprint disease.
It is an object of the invention to be achieved through the following technical solutions:
A kind of containing biphenyl pyrrole bacterium amine and the bactericidal composition of epoxiconazole, this bactericidal composition with biphenyl pyrrole bacterium amine with epoxiconazole is
Principle active component, wherein biphenyl pyrrole bacterium amine is 1～70:1～50 with the mass ratio of epoxiconazole, wherein in bactericidal composition
Active ingredient is present in compositions with enhancing effective amount.
Described bactericidal composition, wherein biphenyl pyrrole bacterium amine is preferably 1～50:1～50 with the mass ratio of epoxiconazole, enters one
Step is preferably 1～30:2～50, the most preferably 1～30:2～10.Biphenyl pyrrole bacterium amine and the preferred mass of epoxiconazole
Proportioning can also be: 70:1,50:1,30:1,20:1,10:1,5:1,2.5:1,1:1,1:2,1:
4,1:6,1:10,1:20,1:30,1:50.
In the compositions of the present invention, the weight/mass percentage composition accounting for compositions both biphenyl pyrrole bacterium amine and epoxiconazole is 2～80%.
Preferably 5～70%.
Described bactericidal composition, wherein with biphenyl pyrrole bacterium amine and epoxiconazole for principle active component and known auxiliary agent and tax
Shape agent is re-dubbed on pesticide any one dosage form allowed.Auxiliary agent known to these, excipient have dispersant, diffusant,
Defoamer, wetting agent, disintegrating agent etc., can use calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, benzylphenol
Polyoxyethylene ether, phenethyl phenol polyethenoxy ether, fatty alcohol-polyoxyethylene ether and similar products, aliphatic amine polyoxyethylene
Ether, fatty acid ethylene oxide addition product, polyoxyethylene polyoxy propylene block compound, castor oil polyoxyethylene ether, nonyl

Hydrochlorate, phosphate, phosphite, lignosulfonates, xanthan gum, phenol formaldehyde condensate, ammonium salt, quaternary etc.
In one or more combinations, excipient includes that Ketohexamethylene, dimethylbenzene, various solvent naphtha, water, antifreezing agent are (such as the third two
Alcohol), deionized water etc..Above auxiliary agent, excipient and other adjuvant can be alone or and use.
Described bactericidal composition, its dosage form is cream, wettable powder, suspending agent, aqueous emulsion or water dispersion granule.
The application on preparation preventing and treating fungal diseases of plants medicine of the above-mentioned bactericidal composition.Especially preventing and treating Cereal,
Application effect in terms of fruit tree, vegetable crop disease is significantly better than single dose and uses.
Above-mentioned application, described fungal diseases of plants is in powdery mildew, rust, downy mildew, damping-off, eyeprint disease
At least one.
The feature of bactericidal composition of the present invention:
1, the biphenyl pyrrole bacterium amine used by the present invention and epoxiconazole, the mechanism of action is different, and mutual mixture will not produce low touching,
Can Synergistic, reduce dosage, reduce cost.
2, the present composition scope of application increases, it is adaptable to preventing and treating Cereal, fruit tree, the refractory fungal disease of vegetable,
Particularly prevent and treat powdery mildew, rust, downy mildew, damping-off, eyeprint disease etc. and all have significant effect.Sterilization group of the present invention
Compound has good prevention effect to ascomycetes, basidiomycetes, Fungi Imperfecti and Oomycete fungal disease；And suppress insect or
Fungus or the antibacterial drug-fast generation to unitary agent (biphenyl pyrrole bacterium amine and epoxiconazole are arbitrary).Bactericidal composite of the present invention
Thing can produce higher synergistic function, and the consumption of the independent reactive compound of amount ratio of this mixture drops significantly
Low, i.e. the activity of mixture is more than the activity of independent component.
Compared with prior art beneficial effects of the present invention: (1), compared with single dose, said composition antagonism fungal disease is such as
The fungal diseases such as powdery mildew, rust, downy mildew, damping-off, eyeprint are sick have obvious synergistic function, overcome and delay
Drug resistance, expanding prevention is composed, hence it is evident that improve prevention effect；(2) preventing and treating recruitment, drug cost are reduced；(3) may be used
Substitute pesticide that is conventional and that be easily generated resistance；(4) compared with single dose, produce and use cost reduces；(5) suppression fungus
Drug-fast generation, its effect uses apparently higher than its single dose.
Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described, and in embodiment, the preparation method of dosage form is conventional method,
" % " of the present invention is mass percent.
Indoor biometrics is tested:
In indoor employing mycelial growth rate method, measure the different agents EC to bacterial strain50Value, uses co-toxicity coefficient calculating side
Method, calculates the co-toxicity coefficient (CTC) of mixture, determines the building performance of mixture, and circular is as follows:
In mixture, a certain single dose (is generally selected EC as standard agent50Junior), calculate:
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
Toxicity index × A the single dose of theoretical toxicity index=A single dose in mixture the toxicity index of proportion+B single dose ×
B single dose proportion in mixture
The EC of actual measurement toxicity index=standard single dose50The EC of value/mixture50Value × 100
Co-toxicity coefficient=actual measurement toxicity index/theory toxicity index × 100
When co-toxicity coefficient classification: CTC is more than 120, mixture has synergetic, is antagonism when CTC is less than 80, CTC
It it is summation action between 80-120.
According to effective ingredient biphenyl pyrrole bacterium amine (A): epoxiconazole (B) quality proportioning is: 80:1,70:1,50:1,
30:1,20:1,10:1,5:1,2.5:1,1:1,1:2,1:4,1:6,1:10,1:20,1:
30,1:50,1:60,1:70 test, and measure its common poison to uncinula necator (Uncinula necator.)
