Description

A kind of nematicidal composition of fluorine-containing thiophene worm sulfone
Technical field
The present invention relates to disinfectant use in agriculture field, and in particular to a kind of nematicidal composition of fluorine-containing thiophene worm sulfone.
Background technology
Fluorine thiophene worm sulfone (Fluensulfone, CAS accession number：318290-98-1, chemical name：The fluoro- 1,3- thiazoles -2- of 5- The fluoro- 3- butene-1s-base sulfones of base -3,3,3- three) it is the fluoroolefins developed by Makhteshim Chemical Works companies Nematicide.Fluorine thiophene worm sulfone, in polypide, can control polypide activity, and then benumb nematode movement by a variety of physiological actions；Resistance Hinder and reduce egg counts or egg hatch rate, control nematode occurs on a large scale；By contact directly kill nematode, make larva without Method is survived, and irreversible nematocidal effect can make nematode dead.
Amino-oligosaccharide (chitosan oligosaccharide) be it is a kind of first degraded to degrade again after chitosan by chitin it is obtained, or by microorganism The low toxicity bactericide obtained is extracted in fermentation.The compound not only to fungi, bacterium, virus is with extremely strong preventing and treating and roots out work With, but also there is nutrition, regulation, removing toxic substances, antibacterial.Research finds that amino-oligosaccharide can induce disease resistance of plant, Preferably prevent and treat the generation of cucumber root-knot nematode.
Nimbin is wide spectrum recognized in the world, efficient, low toxicity, degradable, noresidue insecticide, to nearly all Plant insect, indoor sanitary insect pest etc., which all have, kills effect, and to people and animals and surrounding environment without any pollution.
Ivermectin is new wide spectrum, high-efficiency low-toxicity antibioticses antiparasitic agent, and the mechanism of action is increase polypide The release of inhibitory transmitter γ-aminobutyric acid (GABA), and the Cl ion channels of glutamic acid control are opened, strengthen neu pair Cl permeability, so that the transmission of block nerves signal, plays neural paralysis effect, muscle cell is lost contractility, from And cause polypide dead.There is good preventive effect to animal parasitic nematodes and agriculture nematode.
The agriculture chemical compounding or mixture of reasonable science can expand insecticidal spectrum, improve prevention effect, reduce dosage, less agriculture Medicine is remained, and is extended the Pesticide use life-span, is delayed the generation of pest resistance, be conducive to sustainable development.It there is no at present on fluorine Thiophene worm sulfone respectively with amino-oligosaccharide, nimbin, ivermectin compounding nematicidal composition and its application report.
The content of the invention
In view of this, in order to solve the above problems, the present invention provides a kind of nematicidal composition of fluorine-containing thiophene worm sulfone.This hair Bright process lot of experiments, filters out fluorine thiophene worm sulfone and is compounded respectively with amino-oligosaccharide, nimbin, ivermectin, obtained Nematicidal composition has obvious synergistic effect, and preferable prevention effect is also shown for field test.
To reach above-mentioned purpose, the present invention is adopted the following technical scheme that：
The nematicidal composition of the fluorine-containing thiophene worm sulfone of the present invention, including effective constituents A and active ingredient B；It is described effectively into It is fluorine thiophene worm sulfone to divide A, and the active ingredient B is one kind in amino-oligosaccharide, nimbin or ivermectin.
Further, the weight ratio of effective constituents A and the active ingredient B is 1~25：25~1.
Further, effective constituents A and the active ingredient B account for the percentage by weight of nematicidal composition for 0.1%~ 80%.
Further, the nematicidal composition also includes pesticidal preparations auxiliary element, the pesticidal preparations auxiliary element Including stabilizer, solvent, auxiliary agent and carrier.
Further, the various formulations suitable for agricultural production, including suspending agent, water can be made in the nematicidal composition Emulsion, microemulsion, granule, water dispersible granules, wettable powder.
The nematicidal composition of fluorine-containing thiophene worm sulfone is in terms of preventing and treating vegetable crop, cereal crops, lawn, Pomology disease Application.
Beneficial effects of the present invention are：
The present invention nematicidal composition active component using fluorine thiophene worm sulfone with selected from amino-oligosaccharide, nimbin and she Tie up one kind in rhzomorph and carry out that there is synergistic function, the nematicidal composition between scientific and reasonable compounding, built reactive composition Agriculturally applicable various formulations can be made, nematode can be effectively prevented and treated, the problem of dosage is big, medication is frequent is solved, Slow down environmental pressure, extend the Pesticide use life-span.
Embodiment
In order to be better understood from the present invention, with reference to specific embodiment, the present invention is further illustrated.
The nematicidal composition of the fluorine-containing thiophene worm sulfone of the present invention, including effective constituents A and active ingredient B；The effect composition A For fluorine thiophene worm sulfone, the active ingredient B is one kind in amino-oligosaccharide, nimbin or ivermectin；The effective constituents A and Active ingredient B weight ratio is 1~25：25~1；The percentage by weight of effective constituents A and the active ingredient B, which is accounted for, kills nematode group The 0.1%~80% of compound.Illustrated below using indoor virulence test：
Toxicity Determination
Dip method：The Cucumber root of picking artificial infection cucumber root-knot nematode, is smashed with tissue mashing machine, and 200 are crossed 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 incubate within the 2nd day The larva (2 instar larvae) dissolved is for test.With liquid-transfering gun from low concentration to high concentration, once draw decoction 3mL and be separately added into examination Guan Zhong, then draws the equivalent nematode suspension 3mL prepared and adds in test tube, make decoction and nematode suspension mixed in equal amounts equal It is even.The above-mentioned mixed liquor of certain volume is pipetted with liquid-transfering gun in the aperture of porous biochemical test plate, capping is trained in 25 DEG C of constant temperature Support.Each 4 repetitions of processing, if sterilized water is control treatment.Nematode death condition, record investigation are observed after 48h under anatomical lens Bus borer population and verge of death borer population.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 made according to the niqueMin of drug concentration logarithm value and correspondence plant pathogeny line insect corrected mortality, calculated The LC of each medicament50, 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.
