Description
Technical field
The present invention relates to a kind of bactericidal composition and application thereof, especially one kind is based on Hexanaphthene flusulfamide and thifluzamide
Want bactericidal composition and its application of active component.
Background technology
Hexanaphthene flusulfamide molecular formula：C13H13CIF3NO3S.Chemical name：N- (2- trifluoromethyl-4-chlorophenyls)-alpha-oxo
Cyclohexyl sulfonamide.It has stronger prevention, treatment and osmotically active, there is lasting effect higher.Through table of field test results
It is bright effectively to prevent and treat gray mold, sclerotinia rot of colza, Cucumber Target Leaf Spot and scab.
Thifluzamide (thifluzamide), molecular formula：C13H6Br2F6N2O2S.Chemical name is：The bromo- 2- of 2', 6'- bis-
Methyl -4'- trifluoromethoxy -4- Trifluoromethyl-1s, 3- thiadiazoles -5- hydroxyl anilides.Thifluzamide is to many kinds of fungoid diseases
Evil has good prevention effect, can be widely applied to water paddy and wheat class, peanut, cotton, beet, coffee, potato, lawn etc.
Various crop.It is mainly used in preventing and treating the banded sclerotial blight of paddy rice and wheat class in production at present.
Gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight morbidity are serious in recent years, and calamity is caused to agricultural production
Loss, although Hexanaphthene flusulfamide, thifluzamide single dose have ideal prevention effect to Some Disease, but actually should
In, it has been found that the difficulty of prevention and cure of phytopathogen is increasing, and main cause has：One be with the change of pattern of farming, melon and fruit,
The industrial crops cultivated area such as vegetables progressively expands, and disease occurrence degree, generation quantity increase, and difficulty adds in preventing and treating
Greatly；Two is current climate exception, and the outburst to disease provides certain condition；Three is the selective shadow of long-term chemical medication
Ring so that the resistance of pathogen rises year by year under lasting medicament selection pressure, and the prevention effect of single dose is had a greatly reduced quality.To sum up
Described, current control of plant disease work faces big challenge emphatically.
The content of the invention
The purpose of the present invention be directed to above-mentioned technical problem provide a kind of applied widely, low cost, effect it is good containing ring
The bactericidal composition of own flusulfamide and thifluzamide.
It is a still further object of the present invention to provide the bactericidal composition on the fungal disease that preventing and treating plant epiphyte causes
Using the especially purposes on the fungal diseases such as gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight are prevented and treated.
The purpose of the present invention is realized by following measures：
A kind of bactericidal composition containing Hexanaphthene flusulfamide and thifluzamide, the bactericidal composition is with Hexanaphthene flusulfamide and thiophene furan
Acid amides is principle active component, and wherein Hexanaphthene flusulfamide and the mass ratio of thifluzamide is 1:50~50:1, wherein Bactericidal composite
Effective ingredient is present in composition with enhancing effective amount in thing.
Described bactericidal composition, wherein Hexanaphthene flusulfamide are preferably 50 with the mass ratio of thifluzamide:1~1:10, enter
One step is preferably 20:1~1:2 or 1:7~1:10.Still more preferably it is 10:1~1:2 or 1:7~1:10, inventor has found,
Within this range, not only the bactericidal composition has preferably synergy, and the lasting period is longer.
In bactericidal composition of the present invention, the weight/mass percentage composition that both Hexanaphthene flusulfamide and thifluzamide account for composition is
2%~80%.It is preferred that 10%~70%, more preferably 10%~40%.
Described bactericidal composition, wherein with Hexanaphthene flusulfamide and thifluzamide be principle active component and known auxiliary agent
Any one formulation allowed on agricultural chemicals is re-dubbed with excipient.These known auxiliary agents, excipients have dispersant, diffusant,
Defoamer, wetting agent, disintegrant etc., can use calcium dodecyl benzene sulfonate, APES, benzylphenol polyoxy second
Alkene ether, phenethyl phenol polyethenoxy ether, AEO and its similar products, aliphatic amine polyoxyethylene ether, aliphatic acid
Ethylene oxide adduct, polyoxyethylene polyoxy propylene block compound, castor oil polyoxyethylene ether, NPE,
TWEEN Series, AEO, polyethylene glycol series, Sulfonates, carboxylate, sulfate, phosphate, phosphorous acid
One or more combinations, excipient in salt, lignosulfonates, xanthans, phenol formaldehyde condensate, ammonium salt, quaternary etc.
Including cyclohexanone, dimethylbenzene, various solvent naphthas, water, antifreezing agent (such as propane diols), deionized water.Above auxiliary agent, excipient and
Other auxiliary materials can be with alone or be used in combination.
Described bactericidal composition, its formulation is that missible oil, wettable powder, suspending agent, aqueous emulsion, microemulsion or moisture dissipate
Granule.
Application of the described bactericidal composition on preventing and treating fungal diseases of plants medicine, especially in preventing and treating Cereal, fruit
Application in terms of tree, vegetable crop disease.
Described fungal diseases of plants is gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight etc..
Beneficial effects of the present invention：
1st, the Hexanaphthene flusulfamide used by the present invention is different with the thifluzamide mechanism of action, mutual mixture will not produce it is low tactile,
Can Synergistic, reduction dosage, reduces cost.
2nd, the present composition scope of application increases, it is adaptable to prevent and treat the fungal disease of Cereal, fruit tree, vegetables, special
It is not that application on gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight etc. is prevented and treated has significant effect.The present invention is killed
Bacteria composition has good prevention effect to sac fungus, basidiomycetes, Fungi Imperfecti and Oomycete fungal disease；And suppress insect or
Drug-fast generation of the fungi to unitary agent (Hexanaphthene flusulfamide and thifluzamide are any).Bactericidal composition of the invention can be produced
Synergistic function higher is given birth to, and the consumption of the amount ratio independent reactive compound of the mixture is substantially reduced, that is, mix
Activity of the activity of thing more than independent component.
Beneficial effects of the present invention compared with prior art：(1) compared with single dose, said composition antagonism fungal disease is such as
The fungal diseases such as gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight have obvious synergistic function, overcome and have delayed and be anti-
The property of medicine, expands preventing and treating spectrum, hence it is evident that improve prevention effect；(2) preventing and treating recruitment, drug cost are reduced；(3) alternative routine and easily
Produce the agricultural chemicals of resistance；(4) compared with single dose, production and use cost are reduced；(5) the drug-fast generation of fungi is suppressed, its effect
Fruit uses apparently higher than its single dose.

Indoor biometricses are tested：
Mycelial growth rate method is used indoors, determines EC of the different agents to bacterial strain50Value, using co-toxicity coefficient calculating side
Method, calculates the co-toxicity coefficient (CTC) of mixture, determines the building performance of mixture, and circular is as follows：
A certain single dose (generally selects EC as standard agent with mixture50Junior), calculated：
Single dose toxicity index=standard agent EC50/ certain single dose EC50×100
The virulence of the toxicity index of theoretical toxicity index (TTI)=A single doses × A single doses proportion+B single doses in mixture
Index × B single doses proportion in mixture
The EC of actual measurement toxicity index (ATI)=standard single dose50The EC of value/mixture50Value × 100
Co-toxicity coefficient=actual measurement toxicity index/theoretical toxicity index × 100
Co-toxicity coefficient is classified：Mixture has synergetic when CTC is more than 120, is antagonism when CTC is less than 80, and CTC exists
It is summation action between 80-120.
According to active ingredient Hexanaphthene flusulfamide (A)：Thifluzamide (B) quality proportioning is：70：1、50：1、30：1、20：1、
10：1、5：1、2.5：1、1：1、1：2、1：4、1：7、1：10、1：20、1：30、1：50 are tested, and determine it to wheat sharp eyespot
Co-toxicity coefficient.
