Abstract

Organic arsenical herbicides are currently registered to control weeds in both turfgrass and cotton. Examples of some commonly used organic arsenical herbicides used in Tennessee are monosodium methanearsonate (MSMA), disodium methanearsonate (DSMA) and calcium acid methanearsonate (CAMA).

On April 22nd, 2009, the United States Environmental Protection Agency (EPA) announced the final decision regarding the use of these herbicides for weed management¹. Impacts on the turfgrass and cotton industries are significant.
