Information And Results
Project Deliverables

• This proposal will improve our ability to manage and prevent further evolution of herbicide-resistant weeds in soybean production systems. In addition, we will initiate educational programs on the use and stewardship of new technology such as 2,4-D (Enlist), dicamba (Roundup Ready 2 Xtend), and HPPD (Balance GT and MGI soybean) in preparation for the commercial release of these new herbicide-resistant traits in U.S. soybean production. We are aware that USB projects are funded one year at a time. However, this group has a good track record of producing the outputs proposed in the previous USB proposals and it is highly likely that herbicide-resistant weeds and the release of new soybean herbicide-resistance traits will require educational efforts over the next several years.
• We anticipate more multi-state or regional extension publications or videos will be developed during the multi-year course of this project. We have developed an identification poster of the 11 worst herbicide-resistant weeds in U.S. soybean production (Eleven That Threaten), and produced 15 single page factsheets on the biology and management of each of these weeds. In addition, we have developed a Palmer amaranth identification poster, and a herbicide mode of action poster which outlines the new numbering system for herbicide mode of action. We will update the herbicide mode of action chart annually. We will update the factsheets with recommendations on use of new herbicide-resistant trait technology as soon as they are fully approved for use.
• We anticipate that each state will conduct research and demonstration trials on herbicide-resistant weeds, new soybean herbicide resistance traits, and hold field days at those sites. Each state will have at least one of these research and demonstration sites in each year that the proposal is funded.
• We anticipate that each state will conduct five grower and crop advisor focused meetings or workshops to discuss herbicide resistant weed management. These events will take place between November and July of each year.
• We predict that all who attend the meetings and read the publications will become more knowledgeable of the impact of herbicide resistant weeds on crop production and how to better manage specific weeds that have become more problematic in specific areas.

Final Project Results

Updated December 10, 2019:
This multi-state project was started 6 years ago to inform growers about best management practices for new soybean herbicide resistance traits. Because there was a greater need for information to control herbicide resistant weeds in the early years of this effort, and there were delays in trait regulatory approvals, most of the early work focused on workshops and development of training materials for control of herbicide-resistant weeds in Roundup Ready and non-GMO soybeans. More recently, utilization of Liberty Link and Xtend soybean has grown, cover crop adoption has expanded, thus, the emphasis has shifted towards education and demonstration using these technologies to control weeds. However, there is still a need to continue the education and demonstration process as we learn more about application technologies to keep herbicides from moving off-target, use of diverse cover crops as a weed control tool, and with the recent approval of Enlist soybean and additional herbicide-resistance traited soybean varieties which will be grown commercially in the near future.

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.
