Fruit is apparently higher than the use of its single dose.
Specific implementation mode
The invention will be further described with reference to embodiments, and the preparation method of dosage form is conventional side in embodiment
Method, " % " of the present invention is mass percent.
Indoor biometrics experiment：
Mycelial growth rate method is used indoors, measures EC of the different agents to bacterial strain50Value, using co-toxicity coefficient calculating side
Method calculates the co-toxicity coefficient (CTC) of mixture, determines the building performance of mixture, circular is as follows：
Using a certain single dose in mixture (EC is generally selected as standard agent50Junior), it is calculated：
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
The toxicity index of the toxicity index of theoretical toxicity index=A single doses × A single doses proportion+B single doses in mixture
× B single doses proportion in mixture
The EC of survey toxicity index=standard single dose50The EC of value/mixture50Value × 100
Co-toxicity coefficient=survey toxicity index/theoretical toxicity index × 100
Co-toxicity coefficient is classified：It is antagonism when being less than 80 that mixture, which has synergetic, CTC, when CTC is more than 120, and CTC exists
It is summation action between 80-120.
According to active ingredient fluxapyroxad (A)：Volution bacterium amine (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 are tested, and it is right to measure its
The co-toxicity coefficient of wheat powdery mildew (Blumeria graminis (DC.) Speer=Erysipe graminis DC.).
