He said nitrogen management, with increased cost, will be a critical factor for 2012. “But if you plant behind a failed 2011 crop, you may have residual nitrogen left. Remember, cotton needs 50 pounds of nitrogen to make one bale. Set a realistic yield goal and fertilize accordingly.”

He said deep soil tests, down as far as 24 inches, may reveal residual nitrogen that could allow producers to reduce nitrogen expense for the year.

He said recent research also has shown that foliar potassium applications are not helpful. “By the time potassium deficiencies show up, it’s probably too late to reverse the effect with foliar applications.”

He said growers will have an opportunity this year to use GlyTol/LL cotton varieties, cotton that is tolerant of both glufosinate and glyphosate herbicides. “These GlyTol/LL varieties allow for a strong postemergence weed management program, but farmers still need to apply a residual herbicide,” Morgan said.

He also noted that combining glufosinate and glyphosate in a tank mix is not recommended, especially for tough weeds like waterhemp. “We have seen an antagonistic effect with that tank mix,” he said.

Sharpen harvest aide will be available for 2012, he said.

“And 2, 4-D remains the most effective and most flexible material we have for cotton stalk control,” he said.

He cautioned farmers to be alert to herbicide resistant weed species. Resistance has been identified in waterhemp in south and central Texas and last summer glyphosate resistant Palmer amaranth was identified in the High Plains. “We need to take the appropriate weed management strategies to prevent further spread of the glyphosate resistance pigweed species.”
