Electron transfer and suppress mitochondrial respiratory.It is mainly used on broad leaf crop, preventing and treating the microbial disease of capsule, to Fructus Cucumidis sativi, Cucurbita pepo L. etc.
Downy mildew, powdery mildew on vegetable, downy mildew of fruit tree etc. cause multiple diseases to have favorable effect by pathogenic bacteria.
Carboxin (carboxin), molecular formula：C12H13NO2S.Chemical name：5,6- dihydro -2- methyl isophthalic acids, 4- oxygen thiapyran -3- first
Anilide, or 5,6- dihydro -2- Methyl-N-phenyl-Isosorbide-5-Nitrae-oxathiene -3- Methanamides, chemical structural formula：
Carboxin is crotonamide series bactericidal agent, has higher systemic activity to load guiding principle funguses, is mainly used in preventing and treating crop rust
And smut.Selectivity is strong, using the methods such as seed dressing, vexed kind and seed soaking preventing and treating barley and wheat, Herba bromi japonici, Semen Maydiss, Sorghum vulgare Pers., millet
Deng Cereal smut, also can be used for blade face spray wine preventing and treating Semen Tritici aestivi, beans, the rust such as pears, disease in cotton seedling stage and verticillium wilt,
Damping-off, can also make timber preservative.This product is effective to rhizoctonia, is particularly well-suited to the kind of Cotton Gossypii, Semen arachidis hypogaeae, vegetable and Radix Betae
Subprocessing.Carboxin, but can not be inedible or feeding with eye contact, the seed that Jing carboxins were processed to people and animals' low toxicity.
The difficulty of prevention and cure of phytopathogen is increasing at present, on the one hand, with economy such as the change of pattern of farming, melon fruits and vegetables
Crops planting area progressively expands, and disease occurrence degree, generation quantity increase, and in preventing and treating, difficulty is increased；The opposing party
Face, the resistance of pathogen rise under lasting medicament selection pressure year by year, and the prevention effect of single dose is had a greatly reduced quality, plant disease
Preventing and treating is faced with significant challenge.
The content of the invention
The purpose of the present invention is to provide a kind of applied widely, low cost, effect good fluorine-containing pyrrole bacterium acyl for above-mentioned technical problem
The plant bactericidal composition of amine and carboxin.
The purpose of the present invention is realized by following measures：

Indoor biometricses are tested：
Mycelial growth rate method is adopted indoors, determines different agents to graw mold of tomato bacterial strain (Botrytis cinerea
Pers. EC)50Value, using co-toxicity coefficient computational methods, calculates the co-toxicity coefficient (CTC) of mixture, determines mixture
Building performance, 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 carboxin weight ratio are 1～70：1～50 compositionss are altogether
Malicious coefficient is both greater than 120, has obvious synergistic function to botrytis cinerea.
Field control effectiveness test：
Carried out preventing and treating graw mold of tomato 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 20% carboxin EC 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+carboxin different ratio to graw mold of tomato
As shown in Table 2：Compared with single dose, fluopyram and carboxin compositionss have significant effect to graw mold of tomato,
Higher synergistic function can be produced.The consumption of the amount ratio independent reactive compound of bactericidal composition is substantially reduced, that is, mix
Activity of the activity of thing more than independent component, compared with single dose, reduces preventing and treating recruitment, drug cost.
Shown by indoor biometricses and field efficacy result, fluopyram there is obvious Synergistic to make with carboxin compositionss
With the prevention effect of compositionss is excellent, and prevention effect is better than single dose kind, in agricultural application has using value.
