1. This project is intended to improve our ability to manage and prevent further development of herbicide-resistant weeds in our 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 Plus 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 propose to complete the following projects over a 3-year period of time. 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.
2. We anticipate at least 10 new, 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 7 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.
3. 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 project is funded.
4. 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.
5. 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.
