Description
Technical field
The present invention relates to a kind of Pesticidal combination, particularly to a kind of Insecticidal combinations containing ethyl pleocidin and pyridaben
Thing and purposes.
Background technology
Ethyl pleocidin (Spinetoram) is the secondary metabolitess producing from the fermentation of unwrapping wire bacteria thorn saccharopolyspora strain, for many
The regeneration product of bacteriocidin, its effective ingredient be ethyl pleocidin-J and ethyl pleocidin-L mixture (ratio be 3:
1).It is the biological pesticide developed by The Dow Agrosciences, LLC., have wide spectrum, efficiently, low toxicity, beneficial insect and suckling are moved
The features such as thing is safe.The mechanism of action of ethyl pleocidin is to be subject to by acting on the nicotinic acetylcholine in the nerve of insecticide
Body and r- aminobutyric acid receptors, cause polypide to react insensitive to the signal transmission of irritability or inhibition, thus impact is normal
Neural activity, until dead.
Pyridaben is to be developed by Japanese Nissan chemical company for 1985, and chemical name is the 2- tert-butyl group -5- (uncle 4-
Butyl benzylthio) -4- chlorine pyridazine -3- (2H) ketone.This medical instrument has wide spectrum, the spy such as efficient, contact, quick-acting is good, lasting period length
Point.Pyridaben and other conventional medicament no interactions resistances.There is very strong action of contace poison to evil mite, but no systemic action, to demodicid mite
Class has good prevention effect.
Bemisia tabaci Bemisia tabaci (Gennadius) is a kind of important agricultural pests, and comprises multiple biotypes.
The host range of Bemisia tabaci is very wide, can endanger more than 500 kinds of plant.This worm is except direct sucking plant juice, secretion honey
Outside dew impact photosynthesis of plant, also propagate the viroses of plant, cause huge economic loss to agricultural production.At present, tobacco powder
The preventing and treating of louse is based on chemical prevention, but irrational medicament is different using making field Bemisia tabaci that various medicaments are produced
The Drug resistance of degree.In multiple areas, traditional pesticide is very poor to the cytotoxicity of Bemisia tabaci, leads to Bemisia tabaci to endanger everywhere ferocious
Rampant.Therefore, in the urgent need to can efficiently prevent and treat the medicament of Bemisia tabaci in the actual production of field.
Content of the invention
Present invention aim at providing a kind of Pesticidal combination containing ethyl pleocidin and pyridaben, traditional to solve
Pesticide is very poor to the cytotoxicity of Bemisia tabaci, leads to Bemisia tabaci to endanger the technical matters of wildness everywhere.
Another object of the present invention is to providing the above-mentioned Pesticidal combination containing ethyl pleocidin and pyridaben to be used for
Prevent and treat the purposes of Bemisia tabaci.
The object of the invention is realized by following technical scheme：
A kind of Pesticidal combination containing ethyl pleocidin and pyridaben, described ethyl pleocidin and described pyridaben
Mass ratio is 1:50-50:1.
Preferably, the mass ratio of described ethyl pleocidin and described pyridaben is 1:5-50:1.
Preferably, described ethyl pleocidin and the quality sum of described pyridaben account for described Pesticidal combination gross mass
1%-60%.
Preferably, the described Pesticidal combination containing ethyl pleocidin and pyridaben make water dispersible granules, suspending agent or
Aqueous emulsion.
The above-mentioned Pesticidal combination containing ethyl pleocidin and pyridaben is used for preventing and treating the purposes of Bemisia tabaci.
Compared with prior art, the present invention has following beneficial effect：
The Pesticidal combination of the present invention has significant prevention effect to Bemisia tabaci, can be with notable synergistic, thus agriculture can be reduced
Survival dose, and then reduce cost accounting, drug-fast generation can be delayed, also can reduce the pollution to environment.
Specific embodiment
Pesticidal combination below with the present invention carries out indoor virulence test mensure
1. experiment material：Test medicine adopts 60g/L ethyl pleocidin suspending agent and 15% pyridaben cream；Test worm is
The Q type Bemisia tabaci of indoor feeding hatches the adult of 2 days.
2. experimental technique：Using leaf dipping method, medicament is arranged 5-7 concentration, and made with clear water (containing 1 ‰ Triton-100)
Blank, each concentration does 4 process, processes 30 test worms every time.Take the cabbage leaves of cleaning, make the circle of diameter 4cm
Piece.Take out after blade is soaked 5 seconds in medicinal liquid and dry, by 5% fine jade of the test tube bottom in a diameter of 4cm for the blade the drying pad
On fat, and access 2d Bemisia tabaci adults, top is covered with black gauze.Subsequently the rearing conditions of test worm are：27 ± 1 DEG C of temperature,
Relative humidity 70 ± 5% about, the photoperiod is L：D=14：10.Inspection result after raising 72 hours, touches polypide children with tweezers
Worm normally can not regard as death by scrambler.
3. computational methods：Data is processed with SPSS software statistics.Obtain toxicity regression formula, the lethal concentration of 50, correlation coefficient
Deng, and obtain co-toxicity coefficient (CTC) with the abundant method of Sun Yun.
The co-toxicity of mixture preparation is represented using the co-toxicity coefficient method of Sun Yunpei：
The actual measurement toxicity index (ATI) of mixture preparation=(standard agent LC50/ reagent agent LC50) * 100
(toxicity index ATI of certain medicine × in mixture, this medicine effectively becomes theoretical toxicity index (the TTI)=Σ of mixture preparation
The percentage rate of part).
The co-toxicity coefficient (CTC) of mixture preparation=(mixture preparation actual measurement toxicity index ATI/ mixture preparation theory virulence refers to
Number TTI) * 100
Act on the criteria for classifying according to NY/T1154.13-2008 insecticide combination：If co-toxicity coefficient CTC >=120 are made for potentiation
With；Co-toxicity coefficient (CTC)≤80 is antagonism；80 ＜ co-toxicity coefficient (CTC) ＜ 120 show as summation action.
4. result of the test：Refer to table 1.
The table 1 ethyl pleocidin and pyridaben different ratio indoor joint toxicity measuring result to Bemisia tabaci
Test result indicate that：In this Pesticidal combination, the mass ratio of ethyl pleocidin and pyridaben is 1:5-50:1 scope
When interior, co-toxicity coefficient is all higher than 120, and this Pesticidal combination shows as potentiation to the biological activity of Bemisia tabaci, and potentiation is made
With clearly.
