Description
Technical field
The present invention relates to a kind of bactericidal composition and application thereof, it is especially a kind of using Hexanaphthene flusulfamide and olefin conversion be main
The bactericidal composition of active component and its application.
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 higher lasting effect.Through table of field test results
It is bright effectively to prevent and treat gray mold, sclerotinia sclerotiorum, Cucumber Target Leaf Spot and scab.
Olefin conversion (diniconazole), molecular formula：C15H17Cl2N3O.Chemical name is：(E)-(RS) -1- (2,4- bis-
Chlorphenyl) the amyl- 1 alkene -3- alcohol of -4,4- dimethyl -2- (1H-1,2,4- triazol-1-yls).Olefin conversion belongs to triazole bactericidal agent,
Suppress 14 α-demethylation effect in the ergosterol biosynthesis of fungi, cause ergosterol to lack, cause fungal cell membrane
Abnormal, final fungi is dead, and the lasting period is permanent.To people and animals, beneficial insect, Environmental security.It is to have protect, treat, rooting out
The broad-spectrum germicide of effect；For plurality of plant diseases caused by capsule bacterium, basidiomycetes such as powdery mildew, rust, smut, black star
Disease etc. has special efficacy.
The difficulty of prevention and cure of current phytopathogen is increasing, and main cause has：One is the change with pattern of farming, melon
The industrial crops cultivated area such as fruits and vegetables progressively expands, and disease occurrence degree, generation quantity increase, difficult in preventing and treating
Degree is increased；Two be that current climate is abnormal, and the outburst to disease provides certain condition；Three be the selection of long-term chemical medication
Property influence 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.
In summary, current control of plant disease work faces big challenge emphatically.
The content of the invention
The purpose of the present invention be provide that a kind of applied widely, cost is low for above-mentioned technical problem, effect is good contains ring
The bactericidal composition of own flusulfamide and olefin conversion.
Prevented and treated it is a still further object of the present invention to provide the bactericidal composition caused by plant epiphyte on fungal disease
Using especially preventing and treating the fungies such as gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight, powdery mildew, rust, smut
Purposes in disease.
The purpose of the present invention is realized by following measures：
A kind of bactericidal composition containing Hexanaphthene flusulfamide and olefin conversion, the bactericidal composition is with Hexanaphthene flusulfamide and olefin conversion
For principle active component, the wherein mass ratio of Hexanaphthene flusulfamide and olefin conversion is 1:50~70:1, wherein have in bactericidal composition
Effect composition is present in composition with enhancing effective amount.
The mass ratio of described bactericidal composition, wherein Hexanaphthene flusulfamide and olefin conversion is preferably 50:1~30:1 or 10:1
~1:20 or 1:50, more preferably 10:1~1:10.Still more preferably it is 5:1~1:2 or 1:7~1:10, inventor
It was found that, within this range, not only the bactericidal composition has more preferable synergy, and the lasting period is longer.
In bactericidal composition of the present invention, the weight/mass percentage composition that both Hexanaphthene flusulfamide and olefin conversion account for composition is
2%~80%.It is preferred that 10%~70%, more preferably 10%~40%.
Described bactericidal composition, wherein using Hexanaphthene flusulfamide and olefin conversion as principle active component and known auxiliary agent and
Excipient is re-dubbed any one formulation allowed on agricultural chemicals.These known auxiliary agents, excipients have dispersant, diffusant, disappeared
Infusion, wetting agent, disintegrant etc., can use calcium dodecyl benzene sulfonate, APES, benzyl phenol polyethenoxy
Ether, phenethyl phenol polyethenoxy ether, AEO and its similar products, aliphatic amine polyoxyethylene ether, aliphatic acid ring
Oxidative ethane addition product, polyoxyethylene polyoxy propylene block compound, castor oil polyoxyethylene ether, NPE, tell
Warm series, AEO, polyethylene glycol series, Sulfonates, carboxylate, sulfate, phosphate, phosphite,
One or more of lignosulfonates, xanthans, phenol formaldehyde condensate, ammonium salt, quaternary etc. are combined, and excipient includes
Cyclohexanone, dimethylbenzene, various solvent naphthas, water, antifreezing agent (such as propane diols), deionized water.Above auxiliary agent, excipient and other
Auxiliary material 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, powdery mildew, rust, black
Powder disease etc..
Beneficial effects of the present invention：
1st, the Hexanaphthene flusulfamide used in the present invention is different with the olefin conversion mechanism of action, mutual mixture will not produce it is low tactile, can
Synergistic, reduces dosage, reduces cost.
2nd, present composition scope of application increase, it is adaptable to prevent and treat Cereal, fruit tree, the fungal disease of vegetables, it is special
It is not that application on gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight, powdery mildew, rust, smut etc. is prevented and treated has
Significant effect.Bactericidal composition of the present invention has anti-well to sac fungus, basidiomycetes, Fungi Imperfecti and Oomycete fungal disease
Control effect；And suppress the drug-fast generation of insect or fungi to unitary agent (Hexanaphthene flusulfamide and olefin conversion are any).This hair
Bright bactericidal composition can produce higher synergistic function, and the use of the amount ratio independent reactive compound of the mixture
Amount is substantially reduced, i.e., the activity of mixture is more than the activity of 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, powdery mildew, rust, smut have obvious Synergistic
Effect, overcomes and has delayed the resistance to the action of a drug, expands preventing and treating spectrum, hence it is evident that improve prevention effect；(2) reduce preventing and treating recruitment, medication into
This；(3) alternative routine and the agricultural chemicals for being also easy to produce resistance；(4) compared with single dose, production and use cost reduction；(5) suppress true
Bacterium is drug-fast to be produced, and its effect is used 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, circular is as follows：
A certain single dose (generally selects EC as standard agent using in 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
Survey the EC of 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, and CTC exists when being less than 80 for antagonism, CTC
It is summation action between 80-120.
According to active ingredient Hexanaphthene flusulfamide (A)：Olefin conversion (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 powdery mildew
Co-toxicity coefficient.
