Technical Field
The invention relates to the technical field of pesticides, in particular to a nematicide composition containing lentinan for preventing and treating taro root knot nematode disease.
Background
Plant nematode disease is an important disease species in world agricultural production, with losses caused by root-knot nematodes accounting for over 50%. The root knot nematode hosts are wide, can infect more than 3000 plants, including most crops, can generally cause the crop to reduce the yield by 10-20%, and more than 75% in serious cases. More than 90% of plant root knot nematode disease is reported to be caused by 4 nematodes, such as southern root knot nematodes (Meloidogyne incognita), northern root knot nematodes (Meloidogyne hapla), peanut root knot nematodes (Meloidogyne arenaria) and javaroot knot nematodes (Meloidogynejavanica). Root-knot nematodes mainly exist in soil with the depth of 5-30cm, destroy plant root system structures by invading wounds and forming tumor-shaped root knots, absorb nutrient substances, influence normal metabolic activities of plants, cause the coincidence of infection of other pathogenic bacteria, and weaken or even die plant growth vigor, so that crops are reduced in yield and even are in failure.
The taro is also affected by root-knot nematodes in the taro planting process, and the yield and quality of the taros are affected. The chemical agent is a main means for preventing and controlling the root-knot nematode disease in the taro field at present, and has the advantages of quick acting, stability, low cost and the like. Because the drug resistance of the root-knot nematode is accumulated, the drug effect of a single chemical agent is effective under the conventional dosage, and therefore, the research and development of a novel compound agent for preventing and treating the root-knot nematode is necessary.
Lentinan (Lentinan) is an effective active ingredient extracted from fruiting body of Lentinus Edodes of good quality, and is an immunopotentiator. Clinical and pharmacological studies show that lentinan has antiviral, antitumor, immunity regulating and interferon formation stimulating effects. Application number CN201510172220.7 discloses a nematicidal disease-resistant composition and application thereof, and specifically discloses that fluoroolefin sulfone and lentinan are compounded in an amount of 80:1-1:80 has synergistic effect on the co-toxicity coefficient CTC of greater than 120 in the ratio range of cucumber root-knot nematode combined toxicity measurement.
The inventor finds that the lentinan and cyflumetofen, sulfoxaflor or thiocyclam have synergistic effect on preventing and controlling root-knot nematodes when being compounded through indoor experiments.
At present, no report on the compounding of lentinan and cyflumetofen, sulfoxaflor or thiocyclam is found.
Disclosure of Invention
The invention aims to provide the nematicide composition containing lentinan for preventing and treating the taro root-knot nematode, which has synergistic effect on preventing and treating the root-knot nematode when two active ingredients are compounded, can improve the preventing and treating effect on the root-knot nematode, effectively prevent and treat the taro root-knot nematode, and can provide support for research and development of a compound agent for preventing and treating the root-knot nematode.
In order to achieve the above purpose, the present invention provides the following technical solutions:
The nematicide composition for preventing and treating taro root knot nematode disease contains lentinan, and the active ingredients of the nematicide composition are compounded by lentinan and cyflumetofen or sulfoxaflor; wherein the mass ratio of the lentinan to the cyflumetofen, the sulfoxaflor or the thiocyclam is 1-100:100-1.
Preferably, the mass ratio of the lentinan to the cyflumetofen is 1-60:27-1.
Preferably, the mass ratio of the lentinan to the sulfoxaflor is 1:30-5.
Preferably, the mass ratio of the lentinan to the thiocyclam is 1-7:4-1.
Compared with the prior art, the invention has the following beneficial effects:
After being compounded with cyflumetofen, sulfoxaflor or thiocyclam, the lentinan and the nematicide composition of the invention have synergistic effect on controlling the root-knot nematode of south, and compared with single active ingredients, the nematicide composition of the invention can effectively improve the control effect on the root-knot nematode of taros and can provide support for research and development of a compound agent for controlling the root-knot nematode of taros.
Detailed Description
The invention will be better understood from the following examples, which are described only for illustration of the invention and should not be construed as limiting the invention as detailed in the claims.
Examples: indoor bioactivity test of lentinan compound
1. Test object: nannon root-knot nematode (Meloidogyne incognita)
2. Test agent
96% Lentinus Edodes polysaccharide powder (Shanghai Yuan Ye Biotechnology Co., ltd.)
95% Cyflumetofen (Shanghai Yuan Ye Biotechnology Co., ltd.)
99% Sulfoxaflor (Jiangsu Yiheng pharmaceutical Co., ltd.)
90% Thiocyclam (Heilongjiang Ji Xiangnong chemical Co., ltd.)
The raw materials are dissolved by dimethyl sulfoxide to prepare single-dose mother liquor, then the mother liquor is diluted by 0.1% Tween-80 aqueous solution, a plurality of groups of proportions are arranged, 7 gradient mass concentrations of each single dose and each group of proportion mixture are respectively arranged according to an equal ratio method, and each mass concentration liquid medicine is 50mL for standby.
3. The test method comprises the following steps: (reference to NT/Y1833.1-2009 method for testing nematode dipping in the pesticide section 1 method for inhibiting plant pathogenic nematodes by means of biological assay in pesticide room)
And (3) picking eggs of the root knot nematodes from the roots of the taros, cleaning with clear water, placing the eggs on wet filter paper of a culture dish, and incubating at 25 ℃ to obtain second-instar larvae with consistent instar. Eluting the cultured root-knot nematode with water, filtering, centrifuging at 1000r/min for 2min, discarding supernatant, adding water, centrifuging again, and finally re-suspending the root-knot nematode with water to 400 head/mL for use. Sequentially sucking 3mL of liquid medicine from low concentration to high concentration by a pipette, respectively adding the liquid medicine into a test tube, and then sucking the prepared equivalent nematode suspension into the test tube to uniformly mix the liquid medicine and the nematode suspension in equivalent. And (3) transferring a certain volume of the mixed solution into the small holes of the 24-hole biochemical test plate by using a pipette, covering, and culturing for 24 hours at the constant temperature of 25 ℃. Each treatment was repeated 4 times with treatments containing dimethyl sulfoxide and 0.1% tween-80 in water as controls. Taking 1mL of mixed solution from each treatment, observing the death condition of nematodes under an dissecting lens, and recording the number of bus worms and the number of dead nematodes for investigation when the number of nematodes observed per repetition is not less than 100. Wherein the criterion for nematode death is: nematodes are stiff and cannot flex by touching with hairpins or bamboo pins.

| Lentinan: sulfoxaflor | 1：5 | 4.83 | 1309.11 | 812.61 | 161.10 |
As can be seen from table 2, at 1: within the mass ratio range of 30-5, the co-toxicity coefficient of the lentinan and the sulfoxaflor to the meloidogyne incoordinates is more than 120 after the lentinan and the sulfoxaflor are compounded, and the synergistic effect is shown.

| Lentinan: insecticidal ring | 7：1 | 14.58 | 433.68 | 129.27 | 335.47 |
As can be seen from table 3, at 1-7:4-1, and the co-toxicity coefficient of the lentinan and the thiocyclam to the meloidogyne incoordinates is more than 120 after the lentinan and the thiocyclam are compounded, thus the synergistic effect is shown.
In conclusion, after the lentinan is compounded with the cyflumetofen, the sulfoxaflor or the thiocyclam, the biological activities of the cyhalothrin and the cyhalothrin are synergistic, and compared with a single effective component, the control effect on the taro root knot nematode can be effectively improved.
The foregoing is merely illustrative of the preferred embodiments of this invention and modifications, obvious to those skilled in the art, may be made without departing from the principles of this invention and are within the scope of this invention.
