Especially preventing wheat powdery mildew, rust, downy mildew, late blight etc. has significant effect.Bactericidal composition antithetical phrase of the present invention
Capsule bacterium, basidiomycetes, Fungi Imperfecti and Oomycete fungal disease have good control effect;And inhibit pest or fungi to unitary system
The generation of the drug resistance of agent (volution bacterium amine and Propamocarb are any).Bactericidal composition of the present invention can generate higher synergistic work
With, and the dosage of the amount ratio independent reactive compound of the mixture substantially reduces, i.e., and the activity of mixture is more than independent group
The activity divided.
Beneficial effects of the present invention compared with prior art:(1) compared with single dose, the composition antagonism fungal disease is such as
The fungal diseases such as wheat powdery mildew, rust, downy mildew, late blight have apparent synergistic function, overcome and delayed drug resistance,
Expand prevention spectrum, hence it is evident that improve control effect;(2) prevention recruitment, drug cost are reduced;(3) it alternative routine and is also easy to produce
The pesticide of resistance;(4) compared with single dose, production and application cost reduces;(5) inhibit the generation of fungi drug resistance, effect bright
It is aobvious to be used higher than 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 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 are tested, and measure it to Phytophthora infestans germ
The co-toxicity coefficient of (Phytophthora infestans.).
