In our research THE answer is that there are no silver bullets. Good cotton weed control requires a properly implemented program. We continue to conduct studies which focus on individual herbicides in order to evaluate what they bring to a program. However, a large part of our research has focused on season-long weed control programs.
Palmer amaranth is a major challenge for season long control.
With funding from Cotton Incorporated's state support program we continue to evaluate various herbicides and herbicide programs for Palmer amaranth control. In addition to Palmer amaranth research, we have also evaluated residual herbicides in Roundup Ready cotton. Most of the research continues to focus on residual activity from PPI, PRE, POST or directed applications. With funding through Cotton Incorporated's state support program, we evaluated glyphosate programs with or without a residual herbicide. The objective was to evaluate weed control IF Roundup Ready cotton had crop safety similar to Roundup Ready soybeans.
