Description
Technical field
The present invention relates to pesticide sterilizing composite and application thereof, specifically a kind of with benzothiostrobin and fluorine thiazole
Pyrrole ethyl ketone is the binary complex of effective ingredient, is mainly used in the preventing and treating of disease 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.
Fluorine thiazole pyrrole ethyl ketone (oxathiapiprolin), is piperidyl thiazole isoxazolines antibacterial, and its structure includes
Isoxazole ring, pyrazole ring and thiazole ring, mechanism of action is suppression oxygen steroid binding proteins (OSBP), to Rhizoma Solani tuber osi, Fructus Vitis viniferae, vegetable
By the microbial disease of ovum, there is remarkable preventive effect with on other Featured crops.
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 of benzothiostrobin with fluorine thiazole pyrrole ethyl ketone is combined and conducts in-depth research, in substantial amounts of test by the present inventor
On the basis of, find that benzothiostrobin and fluorine thiazole pyrrole ethyl ketone combines in certain amount ranges, prevent and treat crop downy mildew, epidemic disease,
The Oomycete cause of disease microbial disease performance synergistic functions such as late blight, can give the formulations of pesticide by Technology.
After further study, the present invention is completed.
Summary of the invention
It is desirable to provide it is a kind of containing benzothiostrobin with the bactericidal composition of fluorine thiazole pyrrole ethyl ketone, this bactericidal composition
There is significant synergistic function, can be used for multiple diseases on crops, especially by the microbial disease of Oomycete cause of disease
The preventing and treating of (such as downy mildew, epidemic disease, late blight etc.).
Technical scheme: for achieving the above object, the present invention provides a kind of containing benzothiostrobin and fluorine thiazole pyrrole
The bactericidal composition of ethyl ketone, effective ingredient is benzothiostrobin and fluorine thiazole pyrrole ethyl ketone, benzothiostrobin and the weight of fluorine thiazole pyrrole ethyl ketone

Writing, co-toxicity coefficient (CTC) is 269.70.Visible, benzothiostrobin and fluorine thiazole pyrrole ethyl ketone compound has reasonability and feasibility.
Embodiment nine: benzothiostrobin and the compounding Toxicity Determination to cucumber downy mildew pathogenic bacterium of fluorine thiazole pyrrole ethyl ketone are tried
Test.
Test target:
Cucumber downy mildew pathogenic bacterium Cuba artificial downy mildew (Pseudoperonospora cubensis).
This test uses pot-culture method.Choosing the two panels leaf period cucumber seedling that growing way is consistent, each process selects 5 basins for examination melon
Seedling, numbers standby.Spray under 50PSI pressure with Potter spray tower, every basin 5mL.Each medicament arranges 5 Concentraton gradient,
With spray equivalent clear water as blank.Spray inoculation bacterium of downy mildew of cucumber sporangia suspension, spore after chemicals treatment 24h
The configuration process of capsule suspension is as follows: take the cucumber leaves picking up from field with cucumber downy mildew pathogenic bacterium Cuba artificial downy mildew,
Dip the Sporangium in the distillation washing lower back face of about 10 DEG C with brush pen, being made into concentration is 3 × 105The Sporangium of individual/mL suspends
Liquid.Cucumber seedling is placed in growth cabinet after inoculation (relative humidity 100%, temperature 15-20 DEG C) cultivate, after 24h, keeps temperature
Spending 15-24 DEG C, relative humidity about 90% moisturizing induction, 10d " Invest, Then Investigate " records incidence, calculates disease index and preventing and treating effect
Really.
Carry out statistical analysis with DPS statistical analysis software, calculate the EC of each medicament50, and calculate mixture according to the abundant method of Sun Yun
Co-toxicity coefficient (CTC value).
Actual measurement toxicity index (ATI)=(standard agent EC50/ reagent agent EC50)×100。
Percentage composition+B medicament the toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent.
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theory toxicity index (TTI)] × 100.
According to the NY/T11547.7-2006 insecticide combination effect criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as increasing
Effect effect；Co-toxicity coefficient (CTC)≤80 shows as antagonism；80 ＜ co-toxicity coefficient (CTC) ＜ 120 show as summation action.
Table 2, benzothiostrobin and fluorine thiazole pyrrole ethyl ketone
Toxicity Determination result to cucumber downy mildew pathogenic bacterium Cuba artificial downy mildew
From table 2 it can be seen that benzothiostrobin and fluorine thiazole pyrrole ethyl ketone are compounding in the range of 20:1～1:10 (by weight)
Time, co-toxicity coefficient (CTC) is all higher than 120, and cucumber downy mildew pathogenic bacterium Cuba artificial downy mildew is all shown synergistic function；
Benzothiostrobin and fluorine thiazole pyrrole ethyl ketone are in the range of 10:1～1:1 (by weight), and synergistic function is the most notable, altogether poison system
Number (CTC) is all more than 200；Benzothiostrobin and fluorine thiazole pyrrole ethyl ketone compound with 4:1 (by weight), and synergistic function is the most aobvious
Writing, co-toxicity coefficient (CTC) is 272.40.Visible, benzothiostrobin and fluorine thiazole pyrrole ethyl ketone compound has reasonability and feasibility.
In sum, it is a kind of containing benzothiostrobin with the bactericidal composition of fluorine thiazole pyrrole ethyl ketone that the present invention provides, collaborative
Potentiation is notable, and compared with existing unitary agent, on preventing and treating crops, the effect of disease significantly improves, and pacifies crops
Entirely, popularization and application in agricultural production it are worth.
