Compared with prior art beneficial effects of the present invention: (1) is compared with single dose, the said composition antagonism fungal disease such as fungal disease such as wheat powdery mildew, rust, downy mildew, late blight has obvious synergistic function, overcome and delayed Drug resistance, 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) compared with single dose, produce 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, and " % " 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 computational methods, calculates the co-toxicity coefficient (CTC) of mixture, determine 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 single dose the toxicity index of proportion+B single dose × B single dose proportion in mixture in mixture of theoretical toxicity index=A single dose
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, and CTC is summation action between 80-120.
According to effective ingredient volution bacterium amine (A): Propamocarb (B) quality proportioning is: 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 test, measure its co-toxicity coefficient to Phytophthora infestans pathogenic bacteria (Phytophthora infestans.).
