Nebraska Extension Weed Management Field Day

The Nebraska Extension Weed Management Field Day at the South-Central Ag Lab (SCAL) includes on-site demonstrations of new technology and new herbicides. Tours focus on weed management in Nebraska crops. Field experiments provide information for herbicide-resistant weed control options with various herbicide programs. There are two tours which focus on weed control in soybeans, sorghum and corn. Tour descriptions are listed below:

2026 Tour One: On-Site Demonstration of New Technology/Herbicides for Weed Control in Soybean and Sorghum

• Comparison of Herbicide Programs for Weed Control in Soybean: Unbiased comparison of herbicide programs of different companies for weed control in Roundup Ready 2 Xtend and Enlist soybean. New herbicides and multiple herbicide-resistant soybean will be discussed for the management of herbicide-resistant weeds. 
• Evaluating Ecorobotix ARA Precision Sprayer for Target Weed Control in Soybean and Herbicide Savings: Ecorobotix ARA has developed a precision sprayer for target weed management. It will be compared with broadcast herbicide application. Herbicide savings and weed control will be evaluated. 
• Evaluating the Critical Time of Hairy Vetch Termination for Control of Palmer amaranth in Sorghum and Popcorn: Hairy vetch termination timing will be evaluated after planting sorghum for integrated management of Palmer amaranth in integration with herbicide programs in sorghum.

2026 Tour Two: On-Site Demonstration of New Technology/Herbicides for Weed Control in Corn 

• Comparison of Herbicide Programs for Weed Control in Corn: Unbiased comparison of herbicide programs by different companies for weed control in Roundup Ready/LibertyLink corn. New herbicides in corn will be discussed. 
• Integrated Management of Volunteer Corn in Enlist Corn: Volunteer corn is a major weed in corn-soybean cropping systems. Project will demonstrate how to control volunteer corn in Enlist corn using inter-row cultivator, Assure II, and a premix of glufosinate (Liberty) + quizalofop (Assure II).  
• Effect of Row Spacing and Residual Herbicides on Palmer amaranth Control: The project will evaluate effect of row spacing (15 versus 30 inch) and overlapping residual herbicide program on control and seed production of Palmer amaranth
