Abstract
Mercaptan odors in a thiophosphate compound or formulation are suppressed by treatment of the compound during preparation of the formulation with treatment agents selected from iodine, and alkali and alkaline earth metal hydroxides, hypochlorites and iodates. Depending on the particular agent and method of treatment used, the agent and any reaction products resulting from the treatment may be either removed from the thiophosphate or retained with it in the final formulation. Formulations of particular interest are granular formulations for field application.
