Synergistic supression of grass seedhead production from applications of aminocyclopyrachlor and metsulfuron

Abstract

Disclosed herein are herbicidal compositions comprising a synergistically effective amount for preventing or suppressing grass seedhead production of (a) aminocyclopyrachlor, or an agriculturally acceptable salt or ester thereof, and (b) metsulfuron, or an agriculturally acceptable salt or ester thereof. Also disclosed herein are methods of preventing or suppressing grass seedhead production, which comprise applying to vegetation or an area adjacent the vegetation or applying to soil or water to prevent or suppress grass seedhead production (a) aminocyclopyrachlor, or an agriculturally acceptable salt or ester thereof, and (b) metsulfuron, or an agriculturally acceptable salt or ester thereof, wherein (a) and (b) are each added in an amount sufficient to produce a synergistic grass seedhead-suppressant effect.
