Trifluoro-pyrimidine amide-containing nematicidal compound

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.

AI Technical Summary

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 easy to produce resistance, various types, rich resources, and relatively low development costs. However, biopesticides are difficult to promote vigorously. Disadvantages, the disadvantage is that most biological pesticides are slow-acting pesticides, and the control effect is usually only a few days after application
