Description
Technical field
The invention belongs to pesticide nematicidal field, and in particular to be a kind of nematicidal composition comprising iprodione and its
For preventing the application of crops nematode.
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.
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：
Iprodione belong to dicarboximide class efficiently, wide spectrum, contact killing type fungicide, be a kind of less toxic fungicide, to very much
Fungal disease has very high prevention effect, and nematode is also accompanied by the generation of soil-borne disease in most cases and exists,
Continuous cropping plot soil-borne disease and nematode spore are more serious for many years, while phenomena such as with soil hardening, land capacity degeneration, table
Bright, iprodione also has Plant nematode certain activity, but exclusive use iprodione prevention Plant nematode effect is unsatisfactory,
And the generation of nematode resistance is easy to cause, it is unfavorable for agroecological sustainable development.
Present inventor has carried out depth on this basis by substantial amounts of experiment active ingredient and field control effectiveness test
Enter research, find by after above-mentioned formula (1) compound and iprodione in certain scope to the preventive and therapeutic effect of root-knot nematode
Synergistic function is shown, completes the present invention after further research, at present it is not yet found that the phase compounded on both
Close report.
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 iprodione, its active ingredient include at least formula (1) compound and iprodione,
Wherein, the structural formula of formula (1) compound is as follows：
Further, formula (1) compound and the weight ratio of iprodione are 30:1-1：20.
Further, formula (1) compound and the weight ratio of iprodione are preferably 10:1-5：1.
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, nematicidal composition of the invention can use spraying, pouring root, leaching root, get rid of apply, ditch spread etc., prevent
Preferred ditch spread during nematode, spread manuer in holes, soil treatment or leaching root, seed soaking, the seed pelleting processing such as pouring root.
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 at least has the advantages that：
1st, in nematicidal composition of the invention active ingredient have by the prevention after a certain proportion of compounding to nematode it is bright
Aobvious synergistic function, while some diseases simultaneous can be controlled, play the role of good anti-nematode and keep a full stand of seedings.
2nd, 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.
3rd, iprodione has bactericidal activity in nematicidal composition of the invention, and simultaneous can cure the disease evil.
4th, nematicidal composition of the invention is capable of harm of the cover crop from nematode of long period, lasting period length.
