Sulfur-based functional groups in agrochemistry.

The element sulfur has an outstanding role in the crop protection chemistry because it is used in its elemental form as a multisite fungicide, but is also part of agrochemicals in the form of aromatic or aliphatic sulfur-containing rings or sulfur-based functional groups. This review gives an exhaustive overview over the latter category. Several fundamental agrochemical compound classes are named after a sulfur-based functionality, such as the dithiocarbamate fungicides and sulfonylurea herbicides. Altogether, 16 different sulfur-based functional groups are presented with their typical synthesis approaches and most important representatives in crop protection. © 2023 Society of Chemical Industry.
