2021 Weed Management Field Day Videos

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 several herbicide programs of different companies for weed control in Roundup Ready 2 Xtend, and Enlist soybean. New herbicides and multiple herbicide-resistant soybean cultivars will be discussed.
2. Weed Control and Crop Safety in XtendFlex Soybean: Understand soybean resistant to 2,4-D choline, glyphosate, and glufosinate and their crop safety.
3. Weed Control and Crop Safety in Enlist Soybean: Understand soybean resistant to dicamba, glyphosate, and glufosinate and herbicide programs and their crop safety.
4. Planting Green and Residual Herbicide Interaction: Planting green refers to no-till planting of the primary crop into actively growing cover crop. Cereal rye is the most commonly 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.

Tour 2: On-Site Demonstration of Herbicides for Weed Control in Corn and Sweet 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 XtendFlex Soybean Volunteers in Enlist Corn: Volunteer soybean is not a major issue in corn-soybean cropping systems; however, sometimes it can be an issue. Projects will be demonstrated to control XtendFlex soybean volunteers with PRE and POST herbicides in Enlist corn.
3. Control of Johnsongrass in Roundup Ready Sweet Corn: Grass weed control is a challenge for sweet corn growers. Herbicide options for control of johnsongrass and foxtail in popcorn and Roundup Ready sweet corn will be discussed.
4. 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 traits.
5. Evaluating Atrazine Alternatives for Weed Control in Field Corn: Atrazine is one of the most commonly used herbicides in Nebraska corn production. Due to increasing concern of surface and ground water contamination of atrazine, it is possible that US EPA may restrict atrazine use that will require alternative herbicides for weed control in corn. Herbicide programs without atrazine will be discussed and their performance for residual weed control in corn will be demonstrated.
