Problems solved by technology

Although a single agent of triflumid has good control effect on plant nematodes, long-term use will lead to enhanced resistance of nematodes and shorten the service life of pesticides
[0007] Amino oligosaccharins and chitosan both belong to biopesticides. Biopesticides have the advantages of strong specificity, not ea

Example Embodiment

[0056] Example 1: 20% trifluoroimididine amide·amino-oligosaccharin EC

[0057] Weigh 17% trifluoroimididine amide, 3% amino oligosaccharides, 7% Nongru 500# (calcium dodecylbenzene sulfonate), 8% alkylphenol polyoxyethylene ether, 5% sodium ricinoleate , 8% dimethyl sulfoxide (cosolvent), the remainder of xylene (solvent). Mix and stir trifluoroimididine amide, amino oligosaccharin, cosolvent and solvent to completely dissolve trifluoroimididine amide and amino oligosaccharin, add other additives, and stir evenly to obtain 20% trifluoroimid Rimidamide·Amino-oligosaccharin EC.

[0058] Using the above 20% trifluoroimidamide·amino-oligosaccharin EC for controlling tobacco root knot nematodes, diluted with 400g.a.i. / ha water for root irrigation, the control effect of 14 and 30 days after the treatment is 81.3% and 84.7%. The control agent 5% trifluimidinamide EC was used in the same way as the effective ingredient amount was 400g.a.i. / ha, and the 10% aminooligosaccharin EC was used...

Example Embodiment

[0059] Example 2: 20% Trifluoroimidamide·Chitosan EC

[0060] Weigh 18% trifluoroimidamide, 2% chitosan, 5% sodium lauryl sulfate, 8% alkylphenol polyoxyethylene ether, 5% sodium ricinoleate, 10% dimethyl sulfoxide (Co-solvent), the remainder of xylene (solvent). Mix and stir the trifluoroimididine amide, chitosan, cosolvent and solvent to completely dissolve the trifluoroimididine amide and chitosan, add other additives and stir evenly to obtain 20% trifluoroimid Rimidamide·Chitosan EC.

[0061] Using the 20% trifluimidinamide chitosan EC for controlling tobacco root-knot nematodes, and diluting the root-knot nematodes with 400g.a.i. / ha with water, the control effect is 82.4% and 83.7% at 14 and 30 days after application. For the control agent, 5% trifluimidinamide EC was used in the same way as the effective ingredient amount was 400g.a.i. / ha, and the 10% chitosan EC was used in the same way. The control effects of 5% trifluoroimidamide EC were 77.4% and 73.1% after 14 days an...

Example Embodiment

[0062] Example 3: 50% trifluoroimididine amide·amino-oligosaccharin wettable powder

[0063] Weigh 45% trifluoroimidamide, 5% aminooligosaccharin, 7% fatty alcohol polyoxyethylene ether, 8% sodium lignosulfonate, 8% naphthalenesulfonic acid formaldehyde condensate sodium salt, and the balance is kaolin. According to the above formula, mix trifluoroimididine amide and amino oligosaccharides and other ingredients, stir evenly in a stirring tank, pulverize by jet mill, and mix well to make 50% trifluoroimididine amide·amino oligosaccharide Glycogen wettable powder.

[0064] Using the above 50% trifluoroimidamide·amino-oligosaccharin wettable powder to control tomato root-knot nematodes, dilute the root-knot nematode with 300g.ai / ha with water, the control effect of 82.7% and 84.8 after 14 days and 30 days after application %. The 50% trifluimididine amide wettable powder for the control agent is used in the same way as the effective ingredient amount is 300g.a.i. / ha, and the 20% ami...

Abstract

The invention relates to a trifluoro-pyrimidine amide-containing nematicidal compound. The compound comprises an effective ingredient A, an effective ingredient B and a pesticide preparation auxiliary ingredient, wherein trifluoro-pyrimidine amide is used as the effective ingredient A; one of amino-oligosaccharin or chitosan is selected as the effective ingredient B; the weight ratio of effective ingredient A to effective ingredient B is (50-1) to (1-50); the total content of the effective ingredients is 0.5%-80% of the total weight of the compound. The compound can be prepared into the agriculturally acceptable dosage forms, such as, emulsifiable concentrate, water dispersible granule and water emulsion. The trifluoro-pyrimidine amide-containing nematicidal compound is reasonable in components and has an excellent effect for preventing and treating underground nematode of forest and industrial crops, such as, grain crops, vegetables and fruit trees; compared with the effect for preventing and treating the underground nematode of a single preparation, the effect of the compound has an obvious synergic effect for killing nematode; the dosage is reduced; the pesticide residue is reduced; the pesticide service life is prolonged; the generation of pest drug tolerance is delayed; the safety to the crops is high; the crop stress resistance is obviously increased; the yield and quality are increased.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a nematicide composition containing triflumidazolamide. Background technique [0002] Nematodes belong to the nematode class Nematodes. They are small in size and can only be observed with a microscope. Plant parasitic nematodes mainly include: root-knot nematodes, reniform nematodes, cyst nematodes (Heteroderma genus), and root-spot nematodes (breviphyllous nematodes). Nematodes spread through soil or seeds and can damage the root system of plants; eating plants directly can greatly reduce the absorption of nutrients and water by plants. Nematodes eating plants cause wounds and facilitate the invasion of plant pathogens. Bacteria and viruses interact to form compound infections, which indirectly spread fungal and bacterial diseases caused by other microorganisms, aggravating the damage to crops and causing huge economic pressure. [0003] Fluazaindolizine, the latest amide ...
