Description
Technical field
The invention belongs to pesticide field, and in particular to be a kind of nematicidal composition comprising tioxazafen and its should
With.
Background technology
Nematode belongs to line action thing 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 of intrusion 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 be used 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.
Nematicide tioxazafen, chemical name are 3- phenyl -5- (base of thiophene -2) -1, and 2,4- oxadiazoles, are by Meng
The oxadiazole class nematicide of Shan Dou companies report, the pest control and nematode for being mainly used for soil are handled, in its molecular structure
It need not use that smell is big, with serious pollution raw material without N, P element, in building-up process, the effect of clean manufacturing can be reached, not
Come, nematicide tioxazafen is expected to substitute nematicidal products of the nematicides such as fosthiazate as mainstream.
Known, the 1 of styryl, 3,4- oxadiazole thio-ether type compounds, preparation method and use exist
Announced in CN106674147A, more particularly to a kind of formula (1) compound, there is preferable eelworm-killing activity, its structural formula is as follows：
Present inventor is screened by substantial amounts of toxicity and field control effectiveness test, find above-mentioned formula (1) and
Prevention after tioxazafen compoundings to root-knot nematode in certain scope shows synergistic function, by further grinding
Study carefully and complete the present invention, at present, it is not yet found that the relevant report compounded on both.
The content of the invention
In view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of suitable agriculturally use, safety and environmental protection
Pesticide nematicidal composition, the nematicidal composition is right in certain scope by the reasonable compounding to active ingredient
The prevention of nematode has obvious synergistic function.
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.
To reach above-mentioned purpose, the present invention adopts the following technical scheme that:
A kind of nematicidal composition for including tioxazafen, its active ingredient include at least formula (1) compound and
Tioxazafen, the structural formula of formula (1) compound are as follows：
Further, formula (1) compound and the weight ratio of tioxazafen are 1:30-30:1, it is preferably 1:10-10：1.
Further, the weight percentage of composition shared by active ingredient is 1- in nematicidal composition of the invention
80%, it is preferably 9-60%, remaining is auxiliary element conventional in Pesticide formulation.
Further, nematicidal composition of the invention is prepared by the conventional auxiliary element being aided with Pesticide formulation
Into any one formulation for agriculturally using is adapted to, include 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 component 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：
(1) the active ingredient mechanism of action is different in nematicidal composition of the invention, both can reach in combined use
To significant synergistic function, it is possible to reduce pesticide activity component usage amount, improves prevention effect；
(2) nematicidal agent composition action site of the invention increase, it is possible to reduce and/or overcome the root-knot nematode resistance to the action of a drug
Generation, be conducive to extend pesticide service life.
(3) nematicidal composition dosage of the invention is low, environmentally friendly safety.
