Brief Project Summary:

Due to rapid evolution and spread of herbicide resistance in Palmer amaranth and gradual decrease in the number of effective herbicides in soybean to control this problem weed, results of this study will help growers to make a robust herbicide program in Roundup Ready and Liberty Link soybeans, as well as in the new herbicide-tolerant cultivar such as Roundup Ready 2 Xtend, Enlist, and Balance GT.

Information And Results
Project Deliverables

• An Extension Field Day will be organized at glyphosate-resistant Palmer amaranth research site near Carleton, Thayer County for on-site demonstration of research results to growers, extension educators, and other interested stakeholders.
• This study will be conducted not only to find out the management solution for glyphosate-resistant Palmer amaranth in Nebraska, but also to create state-wide awareness about this troublesome weed species as well as best management practices for management.
• An Extension Field Day will be organized at South Central Ag Lab near Clay Center for on-site demonstration of research results to the growers, extension educators, and other interested stakeholders.
• Four NebGuide publications will be prepared on variety of topics including ‘control of glyphosate-resistant Palmer amaranth in soybean’, ‘Economics of weed control in Xtend, Balance GT, and Enlist soybean’ based on the results of this project, etc.
• Four papers will be published in peer-reviewed journals (Weed Science and Weed Technology) from the results of this project.
• A number of oral presentations will be made to disseminate information from the results of this project to growers, extension educators, and other interested stakeholders during the Crop Production Clinics, Field Days and by writing articles for the CropWatch, Corn & Soybean Digest, Nebraska Farmer, and Nebraska Soybean.
• Time lapse videos will be prepared to emphasize “importance of residual herbicides for weed control in soybean” and “critical period of weed removal in soybean affected by residual herbicide.” The videos will be presented during extension meetings and will be made available on YouTube.

The United Soybean Research Retention policy will display final reports with the project once completed but working files will be purged after three years. And financial information after seven years. All pertinent information is in the final report or if you want more information, please contact the project lead at your state soybean organization or principal investigator listed on the project.
