1, indoor biometrics test:
In indoor employing mycelial growth rate method, measure different agents to the EC of powdery mildew of cucumber bacterial strain (sphaerothecaFuligenea (Schlecht) Poll.)
50value, adopts the co-toxicity coefficient computational methods of the abundant introduction of Sun Yun, calculates the co-toxicity coefficient (CTC) of mixture, determine the building performance of mixture.
With single dose a certain in mixture for standard agent (selects EC usually
50junior), calculate:
Single dose toxicity index=standard agent EC
50/ certain single dose EC
50× 100
Toxicity index × B single dose proportion in mixture of toxicity index × A single dose proportion+B single dose in mixture of theoretical toxicity index=A single dose
The EC of actual measurement toxicity index=standard single dose
50the EC of value/mixture
50value × 100
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100
When CTC is greater than 120, mixture has synergetic, and be antagonism when CTC is less than 80, CTC is summation action between 80-120.
Table 1: fluazinam-ZEN 90160 different ratio is to the indoor biometrics result of powdery mildew of cucumber bacterial strain
| Medicament | Virulence regression equation | EC 50（mg/L） | Co-toxicity coefficient |
| Fluazinam SC(A) | Y=6.27+2.07X | 0.2428 | — |
| ZEN 90160 SC(B) | Y=5.85+1.64X | 0.3015 | — |

| A:B=1:8 | Y=6.11+1.55X | 0.1930 | 152.14 |
As can be seen from Table 1, fluazinam and ZEN 90160 composition have obvious synergistic function.
2, field control effectiveness test:
Powdery mildew of cucumber test is prevented and treated with the pesticidal preparations that above-described embodiment is obtained.
1) test process: this test medicine consumption establishes three concentration for the treatment of respectively according to the difference of each composition, contrast medicament divides
Not commercially available agricultural chemicals 25% ZEN 90160 SC and 50% fluazinam SC and blank clean water experiment.
2) test method: each plot area is 66.7m
2, repeat 3 times; Inspection drug effect side before dispenser after Investigation and Prevention
Method is: random sampling 5 point (getting 2 square metres at often) in test treatment region, checks powdery mildew occurrence degree.
3) result of the test sees the following form:
Table 2: fluazinam-ZEN 90160 different ratio is to the field test results of powdery mildew of cucumber
Note: a represents remarkable in the level of α=0.05, and b represents variant in the level of α=0.05, and c represents not remarkable in the level of α=0.05.
As can be seen from Table 2, the control efficiency of fluazinam and ZEN 90160 composition is excellent, and sterilization speed is fast, the lasting period is long, and control efficiency is all better than single dose kind, in agricultural application, have using value.
