ABSTRACT:
Herbicidally active thiocarbamates are employed in combination with certain mono-, di- or trihaloalkylphosphonodithioates, the latter in sufficient quantity to lessen the rate of soil degradation of the former. As a result, the herbicidal effectiveness of the thiocarbamate is significantly enhanced and prolonged, rendering a single application or multiple applications of the herbicide effective over a longer period of time. Such herbicidal compositions can optionally contain a non-phytotoxic antidotally effective amount of an amide of haloalkanoic or dihaloalkanoic acid. Also novel compounds trichloro- and bromodichloro- methylphosphonodithioates and the process for their preparation are disclosed.
