Embodiment 17:
(1) indoor biometrics test:
In indoor employing mycelial growth rate method, measure different agents to the EC of wheat powdery mildew (Erysiphe graminis DC.f.sp.tritici E Marchal) bacterial strain
50value, adopt co-toxicity coefficient computational methods, calculate the co-toxicity coefficient (CTC) of mixture, determine the building performance of mixture, circular is as follows:
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 co-toxicity coefficient classification: 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: penconazole+metalaxyl different ratio is to the indoor biometrics result of wheat powdery mildew
| Medicament | Virulence regression equation | EC50（mg/L） | Co-toxicity coefficient |
| Penconazole (A) | Y=2.14X+4.16 | 2.471 | - |
| Metalaxyl (B) | Y=1.35X+3.77 | 8.134 | - |
| A:B=1:1 | Y=2.04X+3.17 | 7.876 | 158.43 |
| A:B=1:2 | Y=1.91X+3.15 | 9.353 | 162.30 |
| A:B=1:4 | Y=2.70X+2.06 | 12.251 | 149.87 |
Table 1 indoor biometrics result of the test shows, penconazole and metalaxyl composition co-toxicity coefficient are all greater than 120, have obvious synergistic function to wheat powdery mildew.
(2) field control effectiveness test:
With the pesticidal preparations control wheat powdery mildew test 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 is agricultural chemicals single dose 25% penconazole EC and 15% metalaxyl WP and blank clean water experiment respectively.
2) each plot area of test method is 66.7m
2, repeat 3 times; Investigation drug effect method before dispenser after Investigation and Prevention is: random sampling 5 point (often each sampling 2m in test treatment region
2), carry out severity Scaling according to national field trial relevant criterion, calculate preventive effect.
3) result of the test sees the following form:
Table 2: penconazole+metalaxyl different ratio is to the field control effectiveness test result of wheat powdery mildew
Table 2 field efficacy result shows, penconazole and metalaxyl composition are better than 25% penconazole missible oil and 15% metalaxyl wetting powder to wheat powdery mildew control efficiency, 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.
