The development of LibertyLink cotton will provide additional tools to control weeds postemergence in cotton. Ignite has excellent activity on a variety of broadleaf weeds including annual morningglory and devil's-claw. Weed management systems in LibertyLink cotton were investigated in a number of studies over the past three years. With few exceptions, the most successful weed management programs included the use of residual herbicides at planting followed by Ignite applications postemergence or Ignite plus residual herbicides applied early postemergence. Ignite alone will not effectively control Palmer amaranth, ivyleaf morningglory and devil's-claw season-long.
