Description
Technical field
The present invention relates to technical field of pesticide, more particularly to a kind of nematode that kills containing fluopyram and furfural combines
Thing.
Background technology
Nematode belongs to Nemathelminthes Nematoda, and the bodily form is small, by microscope just it is observed that.Occur in China general
Time, harm is serious, the nematode of plant pest is lived in soil mostly, some is also colonized in plant.Nematode passes through soil
Earth or seed dispersal, the root system of plant can be destroyed；Direct Plant species eaten, the absorption of Plant To Nutrient and moisture can be greatly decreased；
Nematode Plant species eaten causes wound, returns phytopathogen invasion and provides convenience, thus with fungi, bacterium, virus mutually
Effect forms Combined Infection, propagates fungi and bacterial disease as caused by other microorganisms indirectly, has aggravated to crop
Harm, causes huge economic pressures.
Chemical control nematode is most common method at present, mainly uses soil treatment or seed treatment.Nematicide one
As should have preferable lipophilicity and environmental stability, can be spread with liquid or gaseous form in soil, be oozed from nematode epidermal
Toxic action is entered.Most nematicides have to people and animals compared with high toxicity, and some kinds have poisoning to crop.With eelworm harm
Getting worse, it is badly in need of developing new, efficient, less toxic nematicide.
Fluopyram (floupyram), chemical name are：N- { 2- [3- chloro- 5- (trifluoromethyl) -2- pyridine radicals] second
Base }-α, is a kind of new benzamides medicament at the fluoro- 0- toluamides of α, α-three.Fluopyram is initially developed to kill
Microbial inoculum, it is distinctive succinate dehydrogenase inhibitors, is mainly used in preventing and treating by the microbial various plant diseases of fungal pathogen,
Such as gray mold, powdery mildew, late blight, downy mildew, rice blast, sclerotiniose.In addition, fluopyram is to nematodiasis
With preferable prevention effect.Complex II [the i.e. butanedioic acids that fluopyram is acted on mitochondrial respiratory electron transport chain
Dehydrogenase (succinatedehydrogenase, SDH) or butanedioic acid ubiquinone reductase (succinate-coenzyme Q
Reductase, SQR)].Electron transmission in respiratory chain of the fluopyram by blocking succinate dehydrogenase suppresses line grain
The respiration of body.Fluopyram has excellent performance of tagging, and when dosage reaches recommendation dosage, once medicament is and line
Worm is contacted with regard to the nematode that can tag；Have strong uptake and translocation effect in plant, can in effectively preventing nematode invaded plantses body,
Nematode in intrusive body also can effectively be killed.
Furfural, also known as 2 furan carboxyaldehyde, its scientific name are furaldehyde, are that the hydrogen atom on 2, furans is substituted by aldehyde radical
Derivative.Initially from rice bran and diluted acid, heat is made altogether for it, so being called furfural.Furfural is by pentosan water under the action of an acid
Solution generation pentose, then formed by dehydration of pentoses cyclisation.Furfural has to subterranean pest-insect particularly eelworm harm in disclosed report
There is preventive and therapeutic effect, there is synergistic effect with fosthiazate and the abamectin compounded preventing and treating to nematode.
It there is no and reported on the open of the nematicidal composition of fluopyram and furfural compounding at present.
The content of the invention
In consideration of it, it is necessary to be directed to the problem of above-mentioned, there is provided a kind of nematode that kills containing fluopyram and furfural combines
Thing, this composition are formed by fluopyram and furfural compounding, and the preventing and treating to nematodiasis has special efficacy.

To the Toxicity Determination of cucumber root-knot nematode
Dip method：The Cucumber root of artificial infection cucumber root-knot nematode is selected, is smashed with tissue mashing machine, crosses 200 successively
Mesh, 325 mesh, 500 mesh nematode standard screens, with the worm's ovum on the mesh sieve of aseptic water washing 500, hatch in sterilized water, take second day
The larva (2 instar larvae) hatched is for test.With liquid-transfering gun from low concentration to high concentration, once draw decoction 3ml and be separately added into
In test tube, then draw each 3ml of the equivalent nematode suspension prepared and add in test tube, decoction is mixed with nematode suspending agent equivalent
Close uniform.The above-mentioned mixed liquor for pipetting certain volume with liquid-transfering gun is capped, in 25 DEG C of perseverances in the aperture of porous biochemical test plate
Temperature culture.Each four repetitions of processing, if sterilized water is control treatment.Nematode death condition is observed under 48h anatomical lens, record is adjusted
The bus borer population and verge of death borer population looked into.Dead nematode is stiff, and bending motion is still unable to the touching of hair pin.Calculate the death rate
And corrected mortality.
Regression analysis is done according to the niqueMin of drug concentration logarithm value and corresponding plant pathogeny line insect corrected mortality, calculated
The LC50 of each medicament, and according to the co-toxicity coefficient (CTC values) of the abundant method calculating mixtures of Sun Yun.
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50) × 100
A percentage composition+B medicament toxicity index in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
B percentage composition in agent
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100
The co-toxicity coefficient of built agent：CTC >=120 are judged as synergistic effect；CTC≤80 are judged as antagonism；80<CTC<
120 are judged as summation action.
