Description
Technical field
The present invention relates to a kind of bactericidal composition, active ingredient includes fluopyram and terpenol, the Bactericidal composite
Thing can be used for preventing and treating corps diseases especially powdery mildew.
Background technology
Fluopyram be pyridine ethyl benzamide series bactericidal agent, wide sterilization spectrum, for prevent and treat grape, pears and drupe,
Gray mold, powdery mildew, sclerotiniose and candidal disease in the various crop of vegetables and field crop etc. 70.Fluorine pyrrole
Bacterium acid amides be used alone or with other it is bactericide compounded there is extraordinary drug effect under low dosage, and be well suited for disease
Resistance management.Fluopyram acts on Complex II or butanedioic acid the ubiquinone reduction on mitochondrial respiratory electron transport chain
Enzyme, it is first nematicide for acting on this target.
Terpenol is the biological bactericide of biological pesticide company of Israel exploitation, at present, existing 40.2% terpenol mother's medicine
Terpenol missible oil success industrialization with 9%, for preventing and treating the diseases such as powdery mildew of strawberry and early blight of tomato.
The bactericide of long-term use single kind all can inevitably cause the drug-fast generation of pathogen, and by difference
Pesticide species, the especially pesticide activity component of the different mechanisms of action carry out mixture, are to overcome and delay the pathogen resistance to the action of a drug to produce
Raw conventional method.Present inventor has carried out depth on the basis of substantial amounts of Toxicity Determination and field medicine effect test
Enter research, find to make with obvious Synergistic in certain proportion after fluopyram and terpenol compounding
With, and there is outstanding prevention effect to preventing and treating for powdery mildew of cucumber, the present invention is completed after further research, and at present still
Independent of the relevant report that both compound.
The content of the invention
In order that the preventing and treating spectrum of pesticidal preparations further expands, while delaying the drug-fast generation of pathogen, agricultural chemicals is reduced
Usage amount, strengthens compatibility of the agricultural chemicals to environment, it is an object of the invention to propose a kind of having concurrently with synergistic function
The bactericidal composition of good bactericidal effect.
Application another object of the present invention is to provide the bactericidal composition, the bactericidal composition is particularly suited for
Powdery mildew of cucumber is prevented and treated, should be in premorbid or early stage dispenser when using.
In order to achieve the above object, the present invention is adopted the following technical scheme that：
A kind of pesticide sterilizing composite, its active component includes fluopyram and terpenol, wherein, fluopyram and terpene
The weight ratio of enol is 1:30-30：1.
Further, in the bactericidal composition fluopyram and terpenol weight ratio preferably 1:20-10:1 .
Further, in the bactericidal composition active component weight percentage be 5-80%, preferably 10-60%,
Remaining be agricultural chemicals in allow using and acceptable auxiliary element.
Further, bactericidal composition of the invention add different surfactant and carrier and by thickener, disappear
The auxiliary agent of the compositions such as infusion, stabilizer, sticker, antifreeze, is prepared into arbitrarily according to known method in Pesticide formulation
A kind of preparation.
Further, the type of preparation is selected from missible oil, suspending agent, wettable powder, microemulsion, suspension emulsion, aqueous emulsion
Deng.
Further, the frequency of administration and amount of application of bactericidal composition of the invention become with crops, insect, weather condition
Change and the small purpose for changing, effective preventing and treating being reached by applying appropriate dosage.
Further, bactericidal composition of the invention can also contain other agricultural active compositions.
Compared with prior art, bactericidal composition of the invention has the beneficial effect that：
1st, bactericidal composition of the invention is compounded each other has obvious synergistic function in certain proportion,
Lasting period is long, and prevention effect is good；
2nd, the bactericidal composition active component mechanism of action of the invention is different, and energy person's mixture is used being capable of increasing action position
Point, can overcome and/or delay the drug-fast generation of pathogen；
3rd, bactericidal composition prevention effect of the invention is good, while Pesticide use amount can be reduced, to crop safety.
Specific embodiment
In order that technical scheme, purpose and advantage are definitely, illustrated with specific embodiment below,
But the present invention is only limitted to absolutely not these examples, the side that test effect of the invention is combined using indoor biometricses and field test
Formula, unless otherwise instructed, ratio mentioned below is mass ratio.
First, indoor bioassay
1st, for examination pathogen：Cucumber powdery mildew's pathogen；
2nd, the culture of cucumber powdery mildew's pathogen and the preparation of spore suspension
Powdery mildew of cucumber germ is cultivated using plants method under conditions of 20 DEG C, 12h alternation of light and darkness, turns to be commissioned to train foster 1 per 30d
Secondary, with the conidium on aseptic water elution incidence of leaf during inoculation, it is 1 × 10 to be configured to spore concentration6The spore of individual/mL hangs
Supernatant liquid.
3rd, reagent agent：It is solvent dissolving by fluopyram and terpenol active compound acetone, is configured to 10000ug/mL
Mother liquor, it is stand-by in 4 DEG C of Refrigerator stores.
4th, test method：Experiment is with reference to People's Republic of China (PRC) professional standard NY/T 1156.11-2008《It is raw in agricultural chemicals room
The part of thing determination test criterion bactericide the 11st：Preventing and treating cucurbits powdery mildew experiment pot-culture method》, determined using pot-culture method.
Sow susceptible cucumber variety, potted plant to grow to 2 leaf periods standby.The fluopyram and terpenol that will be prepared
Mother liquor is dissolved with 0.1% Tween-80 aqueous surfactant solution and prepares concentration gradient.And set containing only solvent and surfactant
And blank is made in the treatment for not containing effect composition.24 h after chemicals treatment, spray inoculation cucumber powdery mildew's pathogen spore suspension.
The process for preparation of spore suspension is as follows：Take and cover with Powdery Mildew blade, with the aseptic of a small amount of Tween-80 surfactant of refueling
Water washes down spore, double gauze filtering, and 1 × 10 is modulated into after microscopy5The suspension of individual/mL.It is placed in thermostatic chamber after inoculation,
Cultivated 7 days under the conditions of 24 DEG C of temperature.When blank disease liquid rate reaches more than 80%, incidence is managed in classification investigation everywhere,
Calculate the disease index and prevention effect of each treatment.
It is according to the abundant methods of Sun Yun and malicious altogether by the EC50 values and compounding that DPS Software of Data Statistics calculates each chemicals treatment
Coefficient.
Synergy evaluation criterion：Co-toxicity coefficient（CTC）≤ 80 is antagonism, is summation action, CTC during 80 ＜ CTC ＜ 120
>=120 is synergistic effect.Result of the test is as shown in table 1：
Toxicity Determination result as shown in table 1, can be so that fluopyram and terpenol are 1 by table 1:30-30:In the range of 1
Preventing and treating to powdery mildew of cucumber shows certain synergistic function, and even antagonism is generally added beyond the proportion
Effect；Wherein, it is 1 that both compound more preferably proportioning:20-10:1, composition Synergistic in the range of aforementioned proportion
Effect is relative to be become apparent from；And when both compound proportions are 14:When 9, synergistic function is best.
