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

  1. Planting Green and Residual Herbicide Interaction in soybean: Planting green refers to no-till planting of the primary crop into actively growing cover crop. Cereal rye is the most planted cover crop in corn/soybean cropping systems in Nebraska. The objectives of this project are (1) To evaluate effect of planting green on performance of residual herbicides applied pre-emergence for weed control in soybean, and (2) Effect of early termination of cereal rye versus planting green on weed control and soybean yield.
  2. Inter-seeding Small Grains (Barley, Oat, and Wheat) in Soybean for Weed Suppression: Evaluate the effect of inter-seeding small grains into soybean on weed suppression and soybean yield and grain quality.
  3. 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 management of herbicide-resistant weeds.
  4. Evaluating Residual Herbicides for Overlapping Residual Weed Control in Soybean: Can we achieve season-long weed control in soybean by using residual herbicides applied pre-emergence and post-emergence without a foliar active herbicide? This project will discuss the possibility of complete residual weed control in soybean.

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. Control of Corn Volunteers 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 Assure II and a premix of glufosinate (Liberty) + quizalofop (Assure II).
  3. Evaluating Surtain (saflufenacil + pyroxasulfone) for weed control and crop safety in corn & popcorn: Surtain is the new Kixor herbicide based on solid-encapsulation technology, enabling pre- and early-post-emergence application for weed control in corn.
  4. Control of Corn Volunteers in iGrowth and Double Team Sorghum: When sorghum is planted after corn, corn volunteer is a major weed. iGrowth sorghum is a new herbicide-resistant sorghum that provides an opportunity for post-emergence control of grass weeds, including corn volunteers. ImiFlex (imazamox) and Zest (quizalofop) will be evaluated for control of volunteer corn.
