Problems solved by technology

[0004] Long-term use of a single insecticide will easily lead to insect resistance and increase the amount of pesticide used, leading to adverse consequences such as high toxicity, large dosage, large residues, and poor efficacy, and the field of action is relatively single
However, the research and development of pesticide compounds requires a long research and development cycle, and the work of screening compound structures is very complicated, which cannot be undertaken by ordinary research and development institutions.

specific Embodiment approach

[0098] Specific embodiments: combined toxicity of triflumid and fluthiazol in different ratios

[0099] 1.1 Drugs to be tested

[0100] 95.7% of the original drug of triflumidazol, 95% of the original drug of fluthiazol.

[0101] 1.2 Source of tested insects

[0102] Tomato root-knot nematodes with consistent individual size and physiological state were continuously fed for 5 generations indoors.

[0103] 1.3 Two single-dose indoor toxicity assays

[0104] The two original drugs were dissolved with a small amount of acetone by the worm soaking method, and then diluted with 0.1% Tween aqueous solution to form solutions of 5 equal concentrations, which were diluted in beakers for later use, and clear water was used as a control. Immerse tomato root-knot nematodes of the same size in the liquid medicine soaked in the insect cage for 5 seconds. After absorbing the excess liquid medicine, place them in a petri dish with a diameter of 12 cm. The dish is covered with fresh tomato ...

Abstract

The invention provides an insecticide composition containing fluorine thiamethoxam sulfone and trifluoro-pyrimidine amide. The insecticide composition contains the fluorine thiamethoxam sulfone and the trifluoro-pyrimidine amide, wherein the weight ratio of the fluorine thiamethoxam sulfone to the trifluoro-pyrimidine amide is (1 to 60) to (1 to 70). The fluorine thiamethoxam sulfone used by the invention is a new chemical nematicide, which belongs to non-fumigation novel nematicide, has greater difference from a function mechanism of the trifluoro-pyrimidine amide of an insecticide, and has no cross resistance.

Description

technical field [0001] The invention relates to the field of agrochemicals, in particular to an insecticidal composition containing fluthiazol and triflumid. Background technique [0002] Fluthiazol, the English name is fluensulfone, and the chemical name is 5-chloro-1,3-thiazol-2-yl 3,4,4-trifluorobut-3-en-1-yl sulfone. Fluthiazol is the only new chemical nematicide developed in the past 20 years. It is a new type of non-fumigation nematicide and has a good control effect on nematodes in all growth stages. Usually non-fumigant nematicides work by incapacitating the nematodes, but after a period of time the nematodes will resuscitate, whereas fluthiazol completely kills the nematodes. The time for fluthiazol to enter the soil is only 12 hours, while the time for other nematicides to enter the soil is generally about 5 days. It has contact activity, which can free growers from relying on nematicides for fumigation machines for many years. Fluthiazol has low toxicity, low en...
