The difficulty of prevention and cure of current phytopathogen is increasing, and on the one hand, along with the change of pattern of farming, the economic crops such as melon and fruit, vegetables cultivated area progressively expands, and disease occurrence degree, generation quantity all increase, and in control, difficulty strengthens; On the other hand, the resistance of pathogen rises year by year under the medicament selection pressure continued, and the control efficiency of single dose is had a greatly reduced quality, and control of plant disease is faced with significant challenge.
Summary of the invention
The object of the invention is the plant bactericidal composition that a kind of applied widely, containing fluazinam that cost is low, effective and fluopicolide are provided for above-mentioned technical problem.
A further object of the invention is to provide the application of this bactericidal composition on control Cereal, melon and fruit or vegetable crop fungal disease.
The object of the invention is to be realized by following measures:
A kind of bactericidal composition, with fluazinam with fluopicolide for principle active component, wherein fluazinam and fluopicolide weight ratio are 1 ~ 70:1 ~ 50, and preferably 5 ~ 50:10 ~ 50, more preferably 5 ~ 40:10 ~ 40, most preferably be 1:2 ~ 8.
Bactericidal composition of the present invention, the weight percentage that both fluazinam and fluopicolide account for composition is 2 ~ 80%, is preferably 5 ~ 50%, most preferably 8 ~ 40%.
This bactericidal composition can become with fluopicolide any one formulation that agricultural chemicals allows by fluazinam with known additive compound.
The preferred missible oil of described formulation, pulvis, wetting powder, suspending agent, aqueous emulsion or water dispersion granule.
These known auxiliary agents have dispersant, diffusant, defoamer, wetting agent, disintegrant etc.Auxiliary agent can adopt the one or more combinations in methoxyl group fatty acid amido benzene sulfonic acid sodium salt, sodium methylene bis-naphthalene sulfonate, calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, the rare block compound of polyoxyethylene polyoxy third (as agriculture breast 33#), polyoxyethylene nonylphenol ether, cyclohexanone, dimethylbenzene, white carbon, kaolin, aluminium-magnesium silicate, solvent naphtha, water, isopropyl alcohol, ethylene glycol, propane diols, deionized water etc.
The application of bactericidal composition of the present invention on control Cereal, melon and fruit or vegetable crop fungal disease, preferably preparing the application prevented and treated on the germ killing drugs of powdery mildew, anthracnose, scab, penicilliosis, epidemic disease, leaf blight, rust, downy mildew, S.scabies, brown spot, damping off, gray mold, further preferred application on the germ killing drugs of preparation control wheat powdery mildew, pepper anthracnose, balsam pear scab, scutellum rot of orange, powdery mildew of cucumber, early blight of tomato and late blight.
Compared with prior art, beneficial effect of the present invention:
1, the fluazinam that the present invention is used is pyridine amine derivative, dinitroaniline series bactericidal agent, fluopicolide is novel amide-type systemic fungicide, mutual mixture can not produce conflict, can produce obvious synergistic function, expands control spectrum, be particularly suitable for the crop pests such as control paddy rice, wheat, capsicum, banana, mango, pineapple, cucumber, tomato, sterilization speed is fast, the lasting period is long, can reduce dosage, reducing costs when applying.
2, bactericidal composition of the present invention overcomes and has delayed pesticide resistance, inhibits the drug-fast generation of fungi, overcomes the deficiency of a certain composition of single use, the agricultural chemicals of alternative routine and easily generation resistance.

Embodiment 17
The invention will be further described in conjunction with the embodiments, and in embodiment, the preparation method of formulation is conventional method.
1, indoor biometrics test
In indoor employing mycelial growth rate method, measure different agents to the EC of tomato late blight (Phytophthora infestans (Mont.) de Bary) bacterial strain 50value, adopts the co-toxicity coefficient computational methods of the abundant introduction of Sun Yun, calculates the co-toxicity coefficient (CTC) of mixture, determine the building performance of mixture.
With single dose a certain in mixture for standard agent (selects EC usually 50junior), calculate:
Single dose toxicity index=standard agent EC 50/ certain single dose EC 50× 100
Toxicity index × B single dose proportion in mixture of toxicity index × A single dose proportion+B single dose in mixture of theoretical toxicity index=A single dose
The EC of actual measurement toxicity index=standard single dose 50the EC of value/mixture 50value × 100
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100
When CTC is greater than 120, mixture has synergetic, and be antagonism when CTC is less than 80, CTC is summation action between 80-120.
Table 1: fluazinam+fluopicolide different ratio is to the indoor biometrics result of tomato late blight
Medicament Virulence regression equation EC 50（mg/L） Co-toxicity coefficient
Fluazinam SC (A) Y=5.85+1.56X 0.2847 —
Fluopicolide WDG (B) Y=6.14+1.62X 0.1983 —
A:B=1:2 Y=6.37+1.73X 0.1609 137.09
A:B=1:4 Y=6.95+2.18X 0.1279 165.12
A:B=1:8 Y=6.76+2.06X 0.1402 146.37
As can be seen from Table 1, fluazinam and fluopicolide composition have obvious synergistic function.
2, field control effectiveness test:
With the pesticidal preparations control tomato late blight test that above-described embodiment is obtained.
1) test process: this test medicine consumption establishes three concentration for the treatment of respectively according to the difference of each composition, contrast medicament is commercially available agricultural chemicals 50% fluopicolide WDG and 50% fluazinam SC and blank clean water experiment respectively.
2) test method: each plot area is 66.7m2, repeats 3 times; Inspection drug effect method before dispenser after Investigation and Prevention is: random sampling 5 point (getting 10 strain tomatoes at often) in test treatment region, checks late blight occurrence degree.
3) result of the test sees the following form:
Table 2 fluazinam ++ fluopicolide different ratio is to the field test results of tomato late blight
Note: a represents remarkable in the level of α=0.05, and b represents variant in the level of α=0.05, and c represents not remarkable in the level of α=0.05.
As can be seen from Table 2, fluazinam and fluopicolide composition for preventing and controlling excellent effect, sterilization speed is fast, the lasting period is long, and control efficiency is all better than single dose kind, in agricultural application, have using value.
