Palmer Amaranth Control: Size is critically important when it comes to controlling this weed

摘要

Control of Palmer amaranth has become a major issue in many areas of the peanut belt, especially with widespread resist-ance to ALS-inhibiting herbicides such as Cadre, Pursuit, Classic and Strongarm. In recent years, resistance to glyphosate has further increased the difficulty of controlling this weed in cotton and soybean. Even though the challenge seems daunting, there are a number of things growers can do to help make postemer-gence herbicides perform better. Furthermore, some of these items do not directly impact peanut, but anything done in rotation crops that increases control of Palmer amaranth will no doubt pay dividends in peanut.
