(1) indoor biometricses test：
Mycelial growth rate method is adopted indoors, determines different agents to bacterial strain of cucumber downy mildew bacteria (Pseudoperonspora
Cubensis (Berk.Et Curt.) Rost.) EC50Value, using co-toxicity coefficient computational methods, calculates the co-toxicity coefficient of mixture
(CTC), determine the building performance of mixture, circular is as follows：
With in mixture, a certain single dose (generally selects EC as standard agent50Junior), calculated：
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
Toxicity index × the B of the toxicity index of theoretical toxicity index=A single doses × A single doses proportion+B single doses in mixture is mono-
Agent 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/theoretical toxicity index × 100
Co-toxicity coefficient is classified：When CTC is more than 120, mixture has synergetic, and CTC exists for antagonism, CTC when being less than 80
It is summation action between 80-120.

1 indoor biometricses of table test result indicate that, 2-cyano-3-amino-3-phenylancryic acetate and metalaxyl weight ratio are 1～70：1～50 compositionss are malicious altogether
Coefficient is both greater than 120, has obvious synergistic function to bacterium of downy mildew of cucumber.
(2) field control effectiveness test：
Carried out preventing and treating cucumber downy mildew test with pesticidal preparations obtained in above-described embodiment.
1st, test process：This test medicine consumption sets three concentration for the treatment of, comparison medicament point respectively according to the difference of each composition
It is not pesticide single dose 25% 2-cyano-3-amino-3-phenylancryic acetate SC and 25% metalaxyl WP and blank clean water experiment.
2nd, each plot area of test method is 66.7m2, it is repeated 3 times；Investigation drug effect method after investigating and prevent and treat before dispenser
For：5 points of randomization (takes 5m per in the test process area2), the state of an illness is carried out according to national field test relevant criterion
Classification, calculates preventive effect.
3rd, result of the test see the table below：
Table 2：Field efficacy result of the 2-cyano-3-amino-3-phenylancryic acetate+metalaxyl different ratio to cucumber downy mildew
As shown in Table 2：Compared with single dose, 2-cyano-3-amino-3-phenylancryic acetate has significant effect, energy with metalaxyl compositionss to cucumber downy mildew
Produce higher synergistic function.The consumption of the amount ratio independent reactive compound of bactericidal composition is substantially reduced, i.e. mixture
Activity more than independent component activity, compared with single dose, reduce preventing and treating recruitment, drug cost.
Shown by indoor biometricses and field efficacy result, 2-cyano-3-amino-3-phenylancryic acetate there is obvious Synergistic to make with metalaxyl compositionss
With the prevention effect of compositionss is excellent, and prevention effect is better than single dose kind, in agricultural application has using value.
