Description
Technical field
The present invention relates to the preparing technical field of pesticide more particularly to a kind of nematicidal compositions.
Background technology
Plant nematode is a kind of very harmful pathogenic microorganism, is had a very wide distribution, type is various, environment adapts to
Ability is strong, can colonize in root system, stem, leaf, seed, young shoot and the fruit of plant, can be by feeding activity to host plant
Mechanical damage is caused, and robs the nutrition of host plant, especially its esophageal gland secretion can cause host plant that a system occurs
Epidemy becomes, and can also infect host plant jointly with other pathogenic microorganisms, cause compound disease, cause production loss.In the whole world
In range, agricultural losses caused by plant nematode is annual are up to 100,000,000,000 dollars or more, seriously constrain agricultural economy
Development.
The alternative of nematode chemical prevention at present is few, agriculturally prevents nematode and concentrates on substantially and prevents nematode to plant
Invasion.The high-toxic pesticides such as phonamiphos, cadusafos, carbofuran are largely dependent upon in chemical prevention at present, there are prodigious
Environment secret worry, alternative low toxicity nematicide are seldom.And that there is also insecticidal effects is inadequate for the pesticide of existing prevention nematode
Ideal, lasting period short problem.Therefore, for effective controlling disease, environmental protection ecological safety, in effectively control eelworm harm
While, reduce pesticide dosage, reduce pesticide residue, R & D design is a kind of good to Plant nematode killing activity and lasting effect long
Harmless boilogical pesticide, has a very important significance.
Invention content
For the problem that nematicidal composition toxicity in the prior art is high, insecticidal effect is not ideal enough, lasting effect is poor, this hair
It is bright that a kind of nematicidal composition is provided.
In order to solve the above technical problems, technical solution provided by the invention is：
A kind of nematicidal composition, active ingredient are emamectin benzoate B2 benzoates, fluorine thiophene worm sulfone and the root of bidentate achyranthes
Polysaccharide.
Referring now to the prior art, nematicidal composition provided by the invention, by emamectin benzoate B2 benzoates,
The compounding of fluorine thiophene worm sulfone and Inokopolyose, significantly improves the control effect to Plant nematode, in nematicidal composition effectively at
The mechanism of action divided is different, reduces the single selection pressure to nematode, is conducive to that nematode resistance is overcome to generate and delay
The generation speed of nematode resistance, and the pesticide usage amount prepared is low, has excellent lasting effect, reduces spraying times, into one
Step slows down the generation of nematode drug resistance, reduces production cost and drug cost, improves the utilization rate of pesticide, reduce agriculture
Pollution of the medicine to environment has great promotional value.
Emamectin-benzoate, English name are emamectin benzoate, chemical name 4'Table-
Methylamino -4'Deoxidation abamectin benzoate is that one kind of synthesis is new and effective since fermented product AVERMECTIN B1
Semisynthetic antibiotics insecticide has the characteristics that the biological pesticides such as high-efficiency low-toxicity low-residual, nonhazardous, be it is a kind of have desinsection,
Mite killing, eelworm-killing activity macrolide disaccharide insecticides.Presently commercially available the former medicine of AVM be with B1a be it is main effectively at
Point, however at present studies at home and abroad show that, B2a also has a larger application value, B2a to plant root-knot nematode activity highest,
Lasting period in soil is up to 2 months.The experiments such as Vecent prove, the reason of avermectin B2a lasting period length in the soil is,
It is metabolized as avermectin B2a -2,3- ketone by edaphon, which compares avermectin B2a to the activity of root-knot nematode
Higher.Emamectin benzoate B2 benzoate structural formulas are as follows, R1It is emamectin benzoate B2a benzoic acid for ethyl
Salt, R1It is emamectin benzoate B2b benzoates for methyl.First ammonia in emamectin benzoate B2 benzoates in the present invention
The content of base avermectin B2a benzoate is more than 80%.
Fluorine thiophene worm sulfone, english common name：Fluensulfone, the nineties in last century are found, and are taken in the U.S. within 2014
The non-fumigating nematicide that must be registered, fluorine thiophene worm sulfone, in polypide, can control polypide activity, Jin Erma by a variety of physiological actions
Numbness nematode movement；Egg counts or egg hatch rate are hindered and reduce, control nematode occurs on a large scale；It is directly killed by contacting
Nematode makes larva that can not survive, and irreversible nematocidal effect can make nematode dead, have preventive and therapeutic effect to various plants nematode.
Inokopolyose (Achyranthesbidentata Plysaccharzdes, o ABP) is carried from Achyranthes bidentata Bl root
A kind of bioactive polysaccharide taken is to look in the class plant root of bidentate achyranthes the higher active constituent of a kind of content, mainly there is glucose, sweet
3 kinds of monosaccharide components compositions of dew sugar and fructose, are widely present in animal, plant and microorganism cultures, have and slow down aging and resist
Oxidation, treatment asthma, dredging collateral and promoting blood circulation, reduces the multiple pharmacological effects such as blood glucose at antitumor, immunological regulation, has safe, work
With stabilization, Small side effects, widely applicable, small to body damage and not only injectable but also the advantages that can take, it is used as a kind of medium-height grass
Medicine is applied to the anti-system of the diseases such as tumour, meanwhile, environmental type feed addictive is also developed as in Animal husbandry production.

Reason area's eelworm harm is substantially uniform, and ecological environment is identical), each processing is repeated 3 times.It is carried out using the mode of applying, chemicals treatment
Afterwards, the method for taking random sampling, per 5 points of samplings of cell, every 3 plants of random searching amounts to 15 plants, root is dug out, investigation note
Carry root-knot nematode hazard level.
Investigation method refers to testing example 1, and investigation result is as shown in table 3.
3 field control root-knot nematode disease test result of table
Inokopolyose is can be seen that according to the data comparison of embodiment 1-9 in table 1-3 and comparative example 1-6 to be used alone simultaneously
Without nematicidal effect, do not shown to nematode after being compounded with emamectin benzoate B2 benzoates or fluorine thiophene worm sulfone two-spot yet
Synergistic effect.But after emamectin benzoate B2 benzoates, fluorine thiophene worm sulfone and Inokopolyose ternary built use, to nematode
Inactivating efficacy show extremely significant synergistic effect, and synergistic effect is considerably beyond emamectin benzoate B2 benzoates
With the binary combination of fluorine thiophene worm sulfone.Test result shows ternary built nematicidal composition of the invention to control of nematode effect
It is good, the various crops root nematode such as there is apparent synergistic effect, and cucumber, tomato, soybean can be prevented.
The data of embodiment 1-8 are compared as can be seen that in currently preferred emamectin benzoate B2 benzene first
The mass ratio of hydrochlorate, fluorine thiophene worm sulfone and Inokopolyose is 1:0.1-50:0.05-30, especially emamectin benzoate B2 benzene first
The mass ratio of hydrochlorate, fluorine thiophene worm sulfone and Inokopolyose is 1:0.2-10:In the case of 0.1-5, nematicidal composition of the invention
There is more excellent control effect to various crop root nematode, and dosage can be reduced, it is cost-effective, mitigate to ring
The pollution in border.
In conclusion the present invention nematicidal composition in emamectin benzoate B2 benzoates, fluorine thiophene worm sulfone and
Inokopolyose is applied in combination according to special ratios, relative to the emamectin benzoate B2 benzoates of single composition or two components,
Fluorine thiophene worm sulfone and Inokopolyose can obtain the effect of notable synergistic, and dosage is low, both delay the generation of nematode drug resistance,
