Indoor biometricses are tested：
Mycelial growth rate method is adopted indoors, determines different agents to rice sheath blight disease bacterial strain (Thanatephorus
Cucumeris (Frank) Donk) 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, fluopyram and polyoxin weight ratio are 1～70：1～50 compositionss
Co-toxicity coefficient is both greater than 120, has obvious synergistic function to Rhizoctonia solani Kuhn.
Field control effectiveness test：
Carried out preventing and treating rice sheath blight disease 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 41.7% fluopyram SC of pesticide single dose and 10% polyoxin 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 point is carried out according to national field test relevant criterion
Level, calculates preventive effect.
3rd, result of the test see the table below：
Table 2：Field efficacy result of the fluopyram+polyoxin different ratio to rice sheath blight disease
As shown in Table 2：Compared with single dose, fluopyram and polyoxin compositionss have significant effect to rice sheath blight disease
Really, higher synergistic function can be produced.The consumption of the amount ratio independent reactive compound of bactericidal composition is substantially reduced, i.e.,
Activity of the activity of mixture more than independent component, compared with single dose, reduces preventing and treating recruitment, drug cost.
Shown by indoor biometricses and field efficacy result, fluopyram has obvious Synergistic with polyoxin compositionss
Effect, the prevention effect of compositionss are excellent, and prevention effect is better than single dose kind, in agricultural application have using value.
