Description
Technical field
The invention belongs to technical field of pesticide, and in particular to be it is a kind of containing imicyafos and styryl 1,3,
The composition pesticide of 4- oxadiazole thio-ether type compounds and its application as nematicide.
Background technology
Nematode belongs to line action object door line guiding principle, and the bodily form is small, can observe under the microscope.To the nematode of plant pest
About 3000 kinds, in the soil, also some is colonized in plant for life mostly.Nematode can be destroyed by soil or seed dispersal
The root system of plant or the organ for invading aerial part, influence the growth and development of crops, also propagate indirectly by other microorganisms
Caused disease causes very big economic loss.The use of chemical control nematode is the effective ways that modern agriculture generally uses, one
As for soil treatment or seed treatment, nematicide has volatility and non-volatile two class, the former plays fumigation action, Hou Zheqi
Action of contace poison.Should generally have preferable lipophilicity and environmental stability, can be spread in the soil with liquid or gaseous state, from nematode
Epidermis deeply plays toxic action.Most nematicides have people and animals compared with high toxicity, some kinds also have crop poisoning generation.
Imicyafos (AKD-3088) is the group thiophosphate nematicidal reported by Japanese Agro Kanesho companies
Agent.Imicyafos is cyanamide heterocycle type organic as anabasine insecticide thiacloprid, is a kind of organophosphor.It is by
The cyano Asia imidazolidine of asymmetric organophosphor and nicotinic insecticide is composed, and is mainly used for radish, carrot, tomato, sweet potato
And pest and the control of nematode of the crops such as potato.
Known, the 1 of styryl, 3,4- oxadiazole thio-ether type compounds, preparation method and use exist
It is announced in CN106674147A more particularly to a kind of formula (1) compound, there is preferable eelworm-killing activity, structural formula is as follows：
In the actual application of agricultural production, different pesticide activity component kinds are compounded, can not only be prolonged
The generation of slow disease pest drug resistance, and can a dispenser, prevent a variety of pest and disease damages.Different pesticide activity components are compounded,
According to practical application effect, to judge that certain compounding is synergy, addition or antagonism.In most cases, pesticide
Compounding effect is all additive effect, and the compounding for really having synergistic effect is seldom, especially synergistic effect clearly, co-toxicity coefficient
Very high compounding is with regard to less.Present inventor is measured by a large amount of toxicity and field control effectiveness test, and finding will
The 1,3,4- oxadiazoles thio-ether type compounds of the styryl of formula 1 can generate after being compounded with Imicyafos and cooperate with increasing well
Effect acts on, and completes the present invention after further research, at present, it is not yet found that the relevant report about the two compounding.
Invention content
It is an object of the invention to be directed to background above technology, provide it is a kind of have to nematode preferable control effect, with it is single
Agent is significantly reduced compared to dosage, the synergistic nematicidal composition of low toxicity and low residue.
Another object of the present invention is to provide the application of the nematicidal composition, the nematicidal composition is especially suitable
For preventing the crop plants parasitism such as cereal crop, wheat, rice, fruit tree, cotton, vegetables root-knot nematode, cyst nematode, pine
Material nematode etc..
Further, nematicidal composition of the invention is particularly suitable for prevention wheat root-knot nematode and cyst nematode, mandarin orange
Tangerine root-knot nematode, cucumber root-knot nematode, tomato root-knot eelworm, capsicum root-knot nematode, peanut root-knot nematode, soybean cyst nematode Heterodera glycines.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of nematicidal composition for including imicyafos, its active constituent include at least the styryl of 1 structure of formula
1,3,4- oxadiazole thio-ether type compounds and imicyafos, wherein, shown 1 structure of formula is：
Further, 1 compound of formula and the weight ratio of imicyafos are 1:20-30：1, preferably 1:5-10:1.
Further, the weight percentage of composition shared by active constituent is 1- in nematicidal composition of the invention
80%, preferably 8-50%, remaining is auxiliary element conventional in Pesticide formulation.
Further, nematicidal composition of the invention is prepared by the conventional auxiliary element being aided in Pesticide formulation
Into any one dosage form for agriculturally using is suitble to, including but not limited to missible oil, wettable powder, water dispersible granules, suspending agent,
It is any in aqueous emulsion, microemulsion, dispersible oil-suspending agent etc..
Further, the method for application of nematicidal composition of the invention is spraying, pouring root, spreads fertilizer over the fields, ditch spread, spreads manuer in holes,
Also region such as soil or seed treatment that can be by being applied to plant growth etc..
Further, nematicidal composition of the invention can also be applied with other conventional agricultural active ingredient compoundings, including
But it is not limited to other nematicides, insecticide, fungicide, herbicide, plant growth regulator, fertilizer etc..
Compared with prior art, nematicidal composition of the invention has the beneficial effect that：
1st, the active constituent mechanism of action is different in nematicidal composition of the invention, and the two combined use can reach
Significant synergistic function, it is possible to reduce pesticide activity component usage amount improves control effect；
2nd, nematicidal agent composition action site of the invention increases, it is possible to reduce and/or overcome root-knot nematode drug resistance
Generation, be conducive to extend pesticide service life；
3rd, nematicidal composition dosage of the invention is low, environmentally friendly safety.
