One, indoor biometrics test
In indoor employing mycelial growth rate method, measure the different agents EC to bacterial strain50Value, by co-toxicity coefficient computational methods,
Calculating the co-toxicity coefficient (CTC) of mixture, determine the building performance of mixture, circular is as follows:
In mixture, a certain single dose (is generally selected EC as standard agent50Junior), calculate:
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
Toxicity index × A single dose toxicity index × B of proportion+B single dose in mixture of theoretical toxicity index=A single dose is mono-
Agent is 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/theory toxicity index × 100
When co-toxicity coefficient classification: CTC is more than 120, mixture has synergetic, is antagonism when CTC is less than 80, CTC
It it is summation action between 80-120.
The table 1 metconazole+SAN-619F different ratio indoor biometrics result to wheat powdery mildew
Result of the test illustrates, metconazole is compounding with SAN-619F prevents and kill off wheat powdery mildew, all has potentiation in said ratio,
Wherein the potentiation of proportioning 1:1 is the most notable.
The table 2 metconazoles+SAN-619F different ratio indoor biometrics result to wheat scab
Result of the test illustrates, metconazole is compounding with SAN-619F prevents and kill off wheat scab, all has potentiation in said ratio,
Wherein the potentiation of proportioning 1:1 is the most notable.
Two, field control effectiveness test
Indoor biometrics shows preferable Pesticidal composition, it is necessary to carrying out the field medicine effect test of reality, field medicine effect test is in field
Under the influence of integrated environment, whether final evaluation Pesticidal composition has the important means of using value, accordingly, it would be desirable at indoor biometrics
On the basis of the pesticide mixed preparation for preparing by embodiment carry out preventing and treating wheat powdery mildew and the field medicine effect test of wheat scab,
Relatively metconazole and SAN-619F different ratio are to wheat powdery mildew and the preventive effect of wheat scab.Each plot area is 66.7m2,
In test treatment region, use accidental sampling, sample 7 points, 0.5 square metre every, check wheat powdery mildew and gibberella saubinetii
Sick occurrence degree.Comparison medicament is 50% metconazole WG, 40% SAN-619F WP.
The table 3 metconazole SAN-619F different ratio field control effectiveness test to wheat powdery mildew:
Table 3 shows that metconazole SAN-619F different ratio has good prevention effect to wheat powdery mildew, and effect is obvious
It is better than single dose to use, has and significantly coordinate potentiation.
The table 4 metconazole SAN-619F different ratio field control effectiveness test to wheat scab:
Table 4 shows that metconazole SAN-619F different ratio has good prevention effect to wheat scab, and effect is obvious
It is better than single dose to use, has and significantly coordinate potentiation.
Being shown by the result of indoor biometrics and field control effectiveness test, metconazole and SAN-619F compositions have the most collaborative increasing
Effect effect, has excellent prevention effect to wheat powdery mildew and wheat scab, and prevention effect is all better than single dose kind, in agriculture
Industry application has preferable using value.
