2026 TOUR 1: On-Site Demonstration of New Technology/Herbicides for Weed Control in Soybean and Sorghum

  1. 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. 
  2. 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. 
  3. 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 2: On-Site Demonstration of New Technology/Herbicides for Weed Control in Corn 

  1. 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. 
  2. 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).  
  3. Evaluating Greenfield Robotics’ Robot for Palmer amaranth Control in Soybean and Volunteer Corn Control in Popcorn: Greenfield Robotics is a Kansas based company. They have developed 28-inch-wide robots that can cut weeds between crop rows. Control of Palmer amaranth will be evaluated using this non-chemical control method.
