Description
Technical field
The present invention relates to a kind of nematicidal composition comprising iprodione and tioxazafen and its for preventing and treating crops
The purposes of root-knot nematode, both can reach the technique effect of synergy at compounding.
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, live in mostly in soil, what is also had colonizes in plant.Nematode can be destroyed by soil or seed dispersal
The root system of plant, or the organ of aerial part is invaded, growing for influence crops is also propagated by other microorganisms indirectly
Caused disease, causes very big economic loss.The use of chemical control nematode is the effective ways that modern agriculture is generally used, one
As be used for soil treatment or Seed Treatment, nematicide has volatility and non-volatile two class, and the former plays fumigation action, Hou Zheqi
Action of contace poison.Should typically have preferable lipophilicity and environmental stability, can be spread in soil with liquid or gaseous state, from nematode
Epidermis deeply plays toxic action.Most nematicides have to people and animals compared with high toxicity, and some kinds also have poisoning generation to crop.
Nematicide tioxazafen, chemical name is 3- phenyl -5-（The base of thiophene -2）- 1,2,4- oxadiazoles, are by Meng
The oxadiazole class nematicide of Shan Dou companies report, is mainly used in pest control and the nematode processing of soil, 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 main flow.
Iprodione belong to dicarboximide class efficiently, wide spectrum, contact killing type bactericide, be a kind of low toxicity bactericide, to a lot
Fungal disease has very high prevention effect, and nematode is also accompanied by the generation of soil-borne disease in most cases and existed,
Continuous cropping plot soil-borne disease and nematode spore are more serious for many years, while with phenomenons such as soil hardening, land capacity degenerations, table
Bright, iprodione also has certain activity to Plant nematode, but exclusive use iprodione preventing and treating Plant nematode effect is unsatisfactory,
And the generation of nematode resistance is easily caused, it is unfavorable for agroecological sustainable development.
Present inventor has carried out depth on this basis by substantial amounts of experiment active component and field control effectiveness test
Enter research, find the preventive and therapeutic effect table after tioxazafen and iprodione in certain proportion to root-knot nematode
It is now synergy, the present invention is completed after further research.And at present it is not yet found that closing iprodione and tioxazafen
The relevant report of compounding.
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
Agricultural chemicals nematicidal composition, the nematicidal composition is right in certain scope by the reasonable compounding to active component
The preventing and treating 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 fitted
For preventing and treating the parasitic root-knot nematode of the crop plants such as cereal crop, wheat, paddy rice, fruit tree, cotton, vegetables, SCN, pine
Material nematode etc..
Further, nematicidal composition of the invention, which is particularly suitable for use in, prevents and treats wheat root-knot nematode and SCN, 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 is adopted the following technical scheme that:
A kind of nematicidal composition, its active component mainly includes iprodione and tioxazafen, wherein, both are at weight ratio
1:30-30:1。
Further, iprodione and tioxazafen weight ratio are preferably 5 in the nematicidal composition:1-1:10.
Further, iprodione and tioxazafen weight ratio are preferably 17 in the nematicidal composition:40.
Further, the weight percentage of preparation shared by active component is 1- in nematicidal composition of the present invention
70%, preferably 5-40%, 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 preparation for agriculturally using is adapted 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 conventional auxiliary element used in the nematicidal composition includes but is not limited to wetting agent, disperseed
Agent, thickener, antifreezing agent, defoamer, filler etc..
Further, the method for application of nematicidal composition of the invention is spraying, pouring root, spreads fertilizer over the fields, ditch spread, spreaded 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 composition compoundings, including
But it is not limited to other nematicides, insecticide, bactericide, herbicide, plant growth regulator, fertilizer etc..
Compared with prior art, nematicidal composition of the invention has the beneficial effect that：
（1）The nematicide active component mechanism of action of the present invention is different, and both have obvious synergistic effect at compounding, can be with
Reduce pesticide activity component usage amount, improve prevention effect；
（2）The nematicidal agent composition action site increase of the present invention, it is possible to reduce and/or overcome the drug-fast production of root-knot nematode
It is raw, be conducive to extending the service life of agricultural chemicals；
（3）Iprodione has bactericidal activity in the nematicidal composition of the present invention, simultaneous can control disease；
（4）The nematicidal composition of the present invention is to crop safety, and residues of pesticides are low, meet the requirement of safety and environmental protection.
