Embodiment 1

[0037] Embodiment 1: test target: test root-knot nematode [Meloidogyne incongnita (Kofold&White) Chitwood], isolated from tomato root-knot samples in Yifeng store, Jimo, Qingdao, and cultivated and propagated on live tomato plants in the laboratory.

[0038] Test drugs: 90% of the original drug of the compound of formula I, 85% of the original drug of phoxim, and 97% of the original drug of carbofuran.

[0039] Other reagents: acetone, Tween 80, etc.

[0040] Test treatment and method: Dissolve the compound of formula I, phoxim, and carbofuran in acetone, configure it as a high-concentration mother solution, and dilute it with 0.1% Tween 80 aqueous solution containing an appropriate amount of surfactant in equal ratios to form Concentration series, carry out the preliminary test of formula I compound and phoxim, carbofuran and its different proportioning mixtures, on this basis, determine the test concentration range of each mixing. Each drug was treated at 5 concentrations a...

Embodiment 2

[0059] Embodiment 2: 4.0% phoxim compound granule of formula I (1:1)

[0060] Formula: 2.0% phoxim, 2.0% compound of formula I, 2.0% polyvinyl acetate, 1.0% aluminum chloride, 1.0% deionized water, 3.0% sodium lignosulfonate, 2.0% white carbon black, kaolin supplement.

Embodiment 3

[0061] Embodiment 3: 6.0% carbofuran · formula I compound granules (1:2)

[0062] Formula: 2.0% carbofuran, 4.0% compound of formula I, 4.0% polyvinyl acetate, 1.0% aluminum chloride, 3.0% deionized water, 3.0% sodium lignosulfonate, 4.0% white carbon black, kaolin supplement.

[0063] Process technology of emulsifiable concentrate: dissolving the original drug in a solvent according to a certain ratio, then adding a certain amount of emulsifier and other auxiliary agents, stirring and mixing to prepare a homogeneous transparent oily liquid, which is the emulsifiable concentrate of the present invention.

Abstract

The invention discloses a nematicidal composition and application thereof, the nematicidal composition contains an active component A and an active component B, the weight ratio of the active component A to the active component B is 1: 50-50: 1, and the active component A is any one of phoxim and carbofuran; and B is a compound shown as a formula I. The nematicidal composition disclosed by the invention is used for preventing and treating plant parasitic nematodes. The nematicidal composition disclosed by the invention has good nematicidal activity and small toxicity to human and livestock.

Description

technical field [0001] The invention belongs to the technical field of pesticide compositions, and in particular relates to an active component A and an active component B composition used for preventing and treating root-knot nematodes and improving the actual control effect. Background technique [0002] Plant parasitic nematodes are a class of worms that can parasitize plant roots, stems, leaves and other plant tissues. At present, they have become the second largest type of pathogens that endanger agricultural production. According to statistics, the direct economic losses caused by plant parasitic nematodes worldwide every year Losses amounted to $157 billion. Plant parasitic nematodes can not only infect hosts through secretions, but also cause secondary diseases of plants by spreading other plant pathogens. There are as many as 200 genera of plant parasitic nematodes, involving more than 5,000 species. Among them, the main plant parasitic nematodes that endanger agri...
