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

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.
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.
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.
Evaluating Pre-emergence Herbicides for Weed Control in XtendFlex Soybean: Dicamba (XtendiMax) applied alone or in a mixture with other herbicides will be evaluated for early-season weed control in XtendFlex soybean.

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

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.
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) + FOP.
Evaluating Surtain (saflufenacil + pyroxasulfone) for weed control and crop safety in corn: Surtain is the new Kixor herbicide based on solid-encapsulation technology, enabling pre- and early-post-emergence application for weed control in corn.
Control of Corn Volunteers in iGrowth 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) will be evaluated for control of corn volunteers.
