This invention discloses a method for controlling potato scab, relating to the field of crop cultivation methods. The method includes: Step S1, preparing a coating agent: mixing a first active ingredient and a second active ingredient, wherein the first active ingredient is selected from neonicotinoid insecticides or macrolide insecticides, and the second active ingredient is selected from at least one of methoxyacrylates, organosulfur compounds, or inorganic copper fungicides; Step S2, seed potato coating treatment: mixing the coating composition with potato seed potatoes to ensure the composition is uniformly adhered to the seed potato surface; Step S3, sowing. This invention, through the synergistic combination of insecticides and fungicides, controls pathogens and pests at the source, combining growth-stage control and soil treatment to construct a comprehensive, multi-effect control method, improving control efficacy, reducing pesticide usage, and achieving highly efficient control of potato scab.

The present disclosure relates a filter system for an air decontamination device for the removal of volatile organosulfur compounds (VOSCs) from indoor air at room temperature, comprising a filter cartridge, the filter cartridge containing granules and / or pellets made of two zinc compounds, the two zinc compounds being zinc hydroxide, Zn(OH)2, and zinc peroxide, ZnO2, and wherein the filter acts as an absorption filter, reacting irreversibly with the volatile organosulfur compounds that may contaminate the indoor air, either vapors of liquid organic thiols (RSH), of liquid dialkyl oligosulfides (RS-SR and RS–S-SR, including those present in Allium species), and of the solvent carbon disulfide (CS2). The disclosure also relates to a method for removing these groups of volatile organosulfur compounds from indoor air, wherein a controlled airflow of the indoor air is passed through a filter system comprising granules or pellets prepared from zinc hydroxide, Zn(OH)2, and zinc peroxide, ZnO2, and wherein the volatile organosulfur compounds irreversibly react with the hydroxide and peroxide ions of the aggregates (either pellets or granules) to yield solid and innocuous zinc salts, and are thereby captured in the filter system.

This invention presents a novel electrochemically induced method for the synthesis of carbon-sulfur bonds. Organosulfur compounds are important targets in medicine and biology, and also crucial intermediates in organic synthesis. Therefore, the synthesis of these compounds has significant theoretical and practical value. In organic reactions involving the construction of C-S bonds, the one-step synthesis of organosulfur compounds through the functionalization of alkenes has attracted considerable interest from chemists due to its simplicity and high atom economy. Currently, developing more efficient, greener, and transition metal-free olefin functionalization reactions for the construction of C-S bonds has become a goal pursued by chemists. This novel method provides a good method for constructing carbon-sulfur bonds, thereby synthesizing more desired compounds.
