Synergistic weed control from applications of aminocyclopyrachlor and clopyralid

摘要

Disclosed herein are herbicidal compositions comprising a synergistically herbicidal effective amount of (a) aminocyclopyrachlor, or an agriculturally acceptable salt or ester thereof, and (b) clopyralid, or an agriculturally acceptable salt or ester thereof. Also disclosed herein are methods of controlling undesirable vegetation, which comprise applying to vegetation or an area adjacent the vegetation or applying to soil or water to prevent the emergence or growth of vegetation (a) aminocyclopyrachlor, or an agriculturally acceptable salt or ester thereof, and (b) clopyralid, or an agriculturally acceptable salt or ester thereof, wherein (a) and (b) are each added in an amount sufficient to produce a synergistic herbicidal effect.

主权项

1. A method of controlling undesirable vegetation, which comprises applying to vegetation or an area adjacent the vegetation or applying to soil or water to control the emergence or growth of vegetation a composition comprising a herbicidal active ingredient comprising (a) aminocyclopyrachlor, or an agriculturally acceptable salt or ester thereof and (b) clopyralid, or an agriculturally acceptable salt or ester thereof,
wherein (a) and (b) are each added in an amount sufficient to produce a synergistic herbicidal effect and wherein the acid equivalent weight ratio of (a) to (b) is from 1:6 to 2:3, wherein the composition comprises at least one agriculturally acceptable adjuvant, and wherein the undesirable vegetation includes buckhorn plantain or calvary clover.
