Description
Technical field
The present invention relates to a kind of nematicidal composition more particularly to a kind of 1,3,4- oxadiazoles containing styryl
The nematicidal composition and its application of thio-ether type compounds and fluopyram.
Background technology
Nemas is by plant nematode invasion and parasitogenic plant disease.Aggrieved plant can be because of infection thread
Worm absorbs endotrophic and influences normal growth and development；Secretion during nematode metabolism can also stimulate the thin of host plant
Born of the same parents and tissue lead to plant deformity etc., make the agricultural product underproduction and quality decline.The more serious nemas of China has melon
The root knot nematode disease of the various crops such as class, solanaceous vegetables, banana, citrus, soybean cyst nematode, wheat anguina disease, Sweet Potato
Nematodiasis, aphelenchoides besseyi disease, citrus Tylenchulus Semipenetrans disease etc..
Fluopyram, English name fluopyram are a kind of novel benzamides medicament, fluopyram
It is initially developed to fungicide, is mainly used for prevention by the microbial various plant diseases of fungal pathogen, such as gray mold, white powder
Disease, late blight, downy mildew, rice blast, sclerotiniose etc., but in many open reports, fluopyram also has nematodiasis
There is preferably hair control effect, fluopyram insecticidal mechanism is the complex that it is acted on mitochondrial respiratory electron transport chain
II, the respiration of mitochondria, fluopyram are inhibited by the electron transmission in the respiratory chain of blocking succinate dehydrogenase
With excellent performance of tagging, when dosage reaches recommendation dosage, medicament can kill nematode Yi Dan being contacted with nematode, plant
There is strong uptake and translocation effect in object, can also can to the nematode in intrusive body in effectively preventing nematode invaded plants body
Effectively kill.
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, has preferable eelworm-killing activity, structural formula as follows：
Present inventor is screened by a large amount of toxicity and field control effectiveness test, find fluopyram and
Certain synergistic function is shown to the prevention of a variety of nematodes after the compound compounding of above-mentioned formula 1, by further room
It is interior it is raw survey and field control effectiveness test completes the present invention, currently, it is not yet found that relevant report about the two compound synergic.
Invention content
The purpose of the present invention is to provide a kind of 1,3,4- oxadiazoles thio-ether type compounds that active ingredient includes and fluorine pyrroles
The nematicidal composition of bacterium amide, active constituent compounds can play in a certain proportion in the nematicidal composition
Synergistic function, to especially provide one kind for crop root knot nematode disease and Cyst nematode for the prevention and control of crop nematodiasis
Effective management tool.
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, its active constituent include formula 1) compound and fluopyram, wherein formula 1) chemical combination
The structural formula of object is：
Further, the formula 1) weight ratio of compound and fluopyram is 1:20-10:1, the weight ratio is into one
Step preferably 1:5-5:1.
Further, the weight percentage of composition shared by active constituent is 5-80% in the nematicidal composition,
Preferably 15-60%, remaining is auxiliary element conventional in Pesticide formulation.
Further, the nematicidal composition can be prepared by the conventional auxiliary element being aided in Pesticide formulation
At any one dosage form used in suitable agricultural production, including but not limited to missible oil, wettable powder, water dispersible granules, outstanding
It is any in floating agent, aqueous emulsion, microemulsion, dispersible oil-suspending agent etc..
Further, the method for application of the nematicidal composition is spraying, pouring root, spreads fertilizer over the fields, ditch spread, spreads manuer in holes, and also may be used
Pass through the region such as soil or seed treatment etc. for being applied to plant growth.
Further, the nematicidal composition can be also used in compounding with other conventional agricultural active ingredients, 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) it has obvious synergistic function, is administered alone compared with single dose bright between nematicidal composition of the invention
The aobvious control effect improved to crops nematode；
(2) nematicidal composition of the invention can reduce agricultural active ingredient usage amount, improve control effect；
(3) the active constituent mechanism of action is different in nematicidal composition of the invention, and the two, which is used in compounding, to be subtracted
Less or delay the generation of drug resistance, improves the service life of pesticide activity component；
(4) nematicidal composition dosage of the invention is low, activity is good.
Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, present invention following specific examples
It illustrates, but the present invention is limited to absolutely not these examples.It is as described below to be only the preferred embodiment of the present invention, it is used only for explaining
The present invention, but cannot be therefore understands that for the limitation to the scope of the claims of the present invention.It should be pointed out that it is all the present invention spirit and
Any modification, equivalent replacement or improvement etc., should all be included in the protection scope of the present invention made by within principle, therefore,
The protection domain of patent of the present invention should be determined by the appended claims.
One, indoor bioassay
1, target is tested：Meloidogyne incognita；
2, test method：The cucumber root of picking artificial infection Meloidogyne incognita, is smashed to pieces with tissue mashing machine, is used successively
200 mesh, 300 mesh, the sieving of 500 mesh nematode standard screens are configured to ovum suspension with the worm's ovum on 500 mesh nematode of aseptic water washing sieve
Liquid (100 ovum/mL).It is another to set part ovum and hatch in sterile water, the larva (2 instar larvae) for taking hatch for second day for test,
1 compound of formula and the fluopyram of different ratio are tested to nematode larval or ovum suspension (100 nematode/mL, or 100
A ovum/mL, relative humidity 80-90% are cultivated under the conditions of 23-26 DEG C of temperature, are control with clear water, and often processing setting weighs three times
Virulence again).
According to Sun Yunpei's Method, calculates co-toxicity coefficient CTC, the CTC ﹤ 80 after two kinds of medicaments compound by a certain percentage and make for antagonism
With 80≤CTC≤120 are summation action, and CTC ﹥ 120 are synergistic effect, and test result is as shown in table 1：
1 different ratio formula of table, 1 compound compounds the toxicity to cucumber root-knot nematode with fluopyram
As can be seen from Table 1, to the prevention of cucumber root-knot nematode 1 after 1 compound of formula is compounded with fluopyram:20-
10:In the range of 1, co-toxicity coefficient shows as synergistic function 120 or more；Wherein, when the two compound proportion is 1:5-5:
When 1 range, 150 or more, synergistic function is opposite to be become apparent from co-toxicity coefficient.
Two, preparation example
