| Hazard Information | Back Directory | [Description]
Dithiopyr is a pre-emergence herbicide. It has a low aqueous solubility and, based on its chemical properties, is not expected to leach to groundwater. It is usually persistent in both soil and aquatic systems. It has a low toxicity to mammals and birds but is moderately toxic to most aquatic life, honeybees and earthworms. | [Uses]
Herbicide. | [Definition]
ChEBI: Dithiopyr is a member of pyridines, a thioester and an organofluorine compound. | [Production Methods]
The commercial production of dithiopyr involves a multi-step synthesis starting with a pyridine ring as the core structure. Key steps include alkylation to introduce isobutyl and fluorinated side chains, followed by esterification with thiocarboxylic acids to form the dicarbothioate functional groups. The process requires precise control of reaction conditions to ensure selective substitution and high yield. Final steps include purification and formulation. | [Mechanism of action]
Inhibits cell division - a mitotic inhibitor of normal cell division in susceptible plants. Thought to alter microtubule polymerization. | [Pesticide Type]
