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 soil health, weed control, and soybean yield.
  2. Comparison of Herbicide Programs for Weed Control in Soybean: Unbiased compare of several 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.
  3. Inter-seeding wheat in soybean for weed suppression: Evaluate the effect of inter-seeding winter wheat into soybean on small-seeded broadleaf weed suppression and soybean yield and grain quality.
  4. Weed Control and Crop Safety in XtendFlex Soybean: Understand soybean resistant to dicamba, glyphosate, and glufosinate and herbicide programs and their crop safety.

Tour 2: On-Site Demonstration of New Technology/Herbicides for Weed Control in Corn and Sorghum

  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 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 Assure II and if is there any interaction of Assure II and Enlist ONE when applied in a mixture.
  3. Comparison of herbicide programs for weed control in herbicide-resistant sorghum: The objective of this study is to compare weed control in iGrowth, Double Tree, and Inzen sorghum.
  4. Planting Green and Residual Herbicide Interaction in Corn: The objective of this project is to evaluate effect of planting green on performance of residual herbicides applied pre-emergence for weed control and growth and yield of corn.
