TOUR 1: 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 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.
- Evaluating the Critical Time of Hairy Vetch Termination for Control of Palmer amaranth in Sorghum: Hairy vetch termination timing will be evaluated after planting sorghum for integrated management of Palmer amaranth in integration with herbicide programs in sorghum.
- Effect of Planting Date and Metribuzin-based Herbicide Program on Weed Control and Soybean Yield: Growers in Nebraska have started planting soybean early in the season for effective management of Palmer amaranth. Flumioxazin and metribuzin-based herbicide programs will be evaluated for weed control and soybean yield.
Tour 2: On-Site Demonstration of New Technology/Herbicides for Weed Control in Corn
- Evaluate Critical Time of Cereal Rye Termination after Planting Corn: Cereal rye will be terminated at different growth stages of corn to evaluate the termination timing that can suppress palmer amaranth and provide optimum corn yield.
- 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).
- 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 & popcorn. Application timing of Surtain and crop response will be evaluated.
