Evil has good prevention effect；And (fluorine ether bacterium amide and metrafenone are appointed to unitary agent to suppress insect or fungus or antibacterial
One) drug-fast generation.Bactericidal composition of the present invention can produce higher synergistic function, and this mixture
The consumption of the independent reactive compound of amount ratio is substantially reduced, and 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 funguses such as downy mildew of garpe, Phytophthora capsici, the late blight of potato, rice sheath blight disease, cotton seedling blight, wheat powdery mildew
Disease has obvious synergistic function, overcomes and delayed Drug resistance, and expanding prevention is composed, hence it is evident that improve prevention effect；
(2) preventing and treating recruitment, drug cost are reduced；(3) alternative routine and the pesticide being easily generated resistance；(4) with single dose phase
Ratio, produces and use cost reduces；(5) the suppression drug-fast generation of fungus, 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 fluorine ether bacterium amide (A): metrafenone (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 it to rice sheath blight disease (Thanatephorus cucumeris.)
