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 zoxamide
Want bactericidal composition and its application of active component.
Background technology
Hexanaphthene flusulfamide chemical name：N- (2- trifluoromethyl-4-chlorophenyls)-alpha-oxo cyclohexyl sulfonamide.It has
Stronger prevention, treatment and osmotically active, there is higher lasting effect.Grey mold can be effectively prevented and treated through table of field test results is bright
Disease, sclerotinia sclerotiorum, Cucumber Target Leaf Spot and scab.
Zoxamide (zoxamide), molecular formula：C14H16Cl3NO2.Chemical name is：The chloro- N- of 3,5- bis- (the chloro- 1- second of 3-
Base -1- methyl -2- oxopropyls) -4- methyl benzamides.The mechanism of action of zoxamide is very only in Oomycete bactericide
Special, it suppresses sclerotium division by tubulin β-combination of subunit and the rupture of microtubule cytoskeleton.Zoxamide is not
Influence the travelling of zoospore, sporangiocyst formation or sprout.First circulation divided along with sclerotium, the elongation of germ tube is pressed down
System, so as to prevent germ from penetrating host crop.Controlling object is mainly used in preventing and treating oomycetes diseases such as potato and Phytophthora infestans
Disease, cucumber downy mildew and downy mildew of garpe.
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 zoxamide.
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 on the fungal diseases such as gray mold, scab, brown spot, sclerotiniose, banded sclerotial blight, late blight, downy mildew are prevented and treated
Purposes.
The purpose of the present invention is realized by following measures：
A kind of bactericidal composition containing Hexanaphthene flusulfamide and zoxamide, the bactericidal composition is with Hexanaphthene flusulfamide and benzoyl
Bacterium amine is principle active component, and wherein the mass ratio of Hexanaphthene flusulfamide and zoxamide is 1:50~70:1, wherein Bactericidal composite
Effective ingredient is present in composition with enhancing effective amount in thing.
The mass ratio of described bactericidal composition, wherein Hexanaphthene flusulfamide and zoxamide is preferably 30:1~1:1、1:4
~1:7, more preferably 20:1~1:1, still more preferably 10:1~5:1 or 1:1, inventor has found, within this range, not only should
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 zoxamide account for composition is
2%~80%.It is preferred that 10%~70%, more preferably 10%~40%.
Described bactericidal composition, wherein using Hexanaphthene flusulfamide and zoxamide as 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 of salt, lignosulfonates, xanthans, phenol formaldehyde condensate, ammonium salt, quaternary etc. are combined, excipient
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, late blight, downy mildew
Deng.
Beneficial effects of the present invention：
1st, the Hexanaphthene flusulfamide used in the present invention is different with the zoxamide mechanism of action, mutual mixture will not produce it is low tactile,
Can Synergistic, reduce dosage, reduce 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, late blight, downy mildew etc. is prevented and treated has significantly
Effect.There is bactericidal composition of the present invention preventing and treating well to imitate to sac fungus, basidiomycetes, Fungi Imperfecti and Oomycete fungal disease
Really；And suppress the drug-fast generation of insect or fungi to unitary agent (Hexanaphthene flusulfamide and zoxamide are any).The present invention
Bactericidal composition can produce higher synergistic function, and the consumption of the amount ratio independent reactive compound of the mixture
Substantially reduce, 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, late blight, downy mildew have obvious synergistic function,
Overcome and delayed the resistance to the action of a drug, expand 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 the agricultural chemicals for being also easy to produce resistance；(4) compared with single dose, production and use cost reduction；(5) the anti-medicine of fungi is suppressed
The generation of property, 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)：Zoxamide (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 tomato late blight
