Patent number: 4762548Abstract: Herbicidally active thiolcarbamates are employed in combination with a certain amide extender compound, the latter in sufficient quantity to minimize soil degradation and to prolong the soil life of the former. As a result, the herbicidal effectiveness of the thiolcarbamate herbicide 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 thiolcarbamate herbicide antidote.Type: GrantFiled: August 12, 1985Date of Patent: August 9, 1988Assignee: Stauffer Chemical Co.Inventors: Reed A.
