Control of Perennial Ragweed on Western Nebraska Rangeland

Abstract

One application of 2,4-D 2,4,5-T, and 2,4-D plus 2,4,5-T by aerial and ground equipment usually gave excellent control of perennial ragweed. A repeat application of the herbicide one year after original treatment increased control but generally not enough to warrant retreatment. In many plots perennial ragweed persisted after two herbicide applications.
