Abstract

The invention discloses a nematode killing composition. Active components of the composition comprise fluensulfone and amino-oligosaccharin according to a mass ratio of 1:80-80:1. The composition can thoroughly control nematodes in the whole growth stage of crops, and has the advantages of good effect, low cost, substantial synergistic effect, and improvement of the resistance of crops to virus diseases, blight, epidemic diseases and other soil borne diseases.

Description

Technical field [0001] The invention relates to a pesticide composition, in particular to a nematicidal composition containing fluorosulfone and its application. Background technique [0002] The plant parasitic nematodes mainly include: Root-knot nematodes, Reniformes, Heteroderm, Brachychia, Sphaerotheca spp., Saccharomyces spp., Dictyodera, Trichosanthes, Agaricola spp. Nematodes not only directly harm host plants, but also spread bacteria and viruses. Chemical control of nematodes occupies an important position in the control process, but most of the chemical nematicides currently used are highly toxic pesticides, which have many problems such as high toxicity, serious environmental pollution, insignificant control effects, and nematode resistance. . [0003] Fluorine sulfone, CAS registration number: 318290-98-1, English name: Fluensulfone, trade name: MCW-2, test code: BYI1921, MAI-08015, MAI-08016, other names: Nimitz, perfluorosulfone, fluorine Clothiane and flufenoxine ...
