South Central Weed Management Field Day is June 26

South Central Weed Management Field Day is June 26

Growers, crop consultants, ag professionals, and extension educators are encouraged to attend Nebraska Extension's Weed Management Field Day. It will be held from 8.30 a.m. to 1 p.m. June 26 at the University of Nebraska–Lincoln’s South Central Agricultural Laboratory near Clay Center.

The field day will include on-site demonstrations of herbicides for weed control in corn, popcorn, and soybean. The first tour will begin at 8:30 and focus on weed control in soybeans; the second tour will begin at 10:15 and focus on weed control in corn and popcorn. In addition to the tour topics, Bob Klein, Emeritus Extension Professor, will speak on "What Works and Doesn't Work in Managing Spray Drift."

“A number of projects will be demonstrated during the field day, including weed control in XtendFlex soybean, Enlist Corn, and Alite 27 Soybean,” said Extension Weed Management Specialist Amit Jhala.

New this year is a study on terminating cereal rye before and after planting soybean and control of volunteer corn in Enlist Corn. 

There is no cost to attend the field day, but participants are asked to register at http://agronomy.unl.edu/fieldday. Certified Crop Advisor (CCA) continuing education credits are available. Please see program flyer for more information or contact Amit Jhala at amit.jhala@unl.edu or 402-472-1534.

Tour 1: On-Site Demonstration of New Technology/Herbicides for Weed Control in Soybean

Field demonstrations include:

  • Comparison of herbicide programs for weed control in Roundup Ready 2 Xtend and Liberty Link soybean, including new herbicides and soybean cultivars with multiple-resistance to herbicides
  • Weed control and crop safety in XtendFlex soybean, including soybean resistance to dicamba, glyphosate, and glufosinate
  • Weed control and crop safety in Alite 27 Soybean, including soybean resistance to dicamba, glyphosate, and glufosinate
  • Terminating cereal rye using glyphosate alternatives to reduce the chances of glyphosate resistance evolving in winter annual weeds.

Tour 2: On-Site Demonstration of Herbicides for Weed Control in Corn

Field demonstrations include:

  • Comparison of herbicide programs for weed control in  glyphosate- and glufosinate-resistant corn; new corn herbicides
  • Control of Roundup Ready/LibertyLink volunteer corn in Enlist Corn
  • Control of Johnsongrass and foxtails in white and yellow popcorn.
  • Evaluating weed control efficacy of DiFlexx or DiFlexx DUO with and without ammonium sulfate (AMS). Also, will using a higher labeled rate of DiFlexx or DiFlexx DUO provide higher weed control efficacy compared with the lower labeled rate when applied without AMS.
