• This project is intended to improve our ability to manage these weeds in our current soybean production systems and increase grower awareness of the impact of glyphosate-resistant weeds and other herbicide-resistant weeds. 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 Extend), and HPPD (Balance/Callisto Beans) in preparation of approval and use of these new herbicide tolerance traits in U.S. soybean production.
• We anticipate that at least 3-5 new, multi-state or regional extension publications or videos will be developed each year.
• We anticipate that each state will conduct research and demonstration trials on herbicide-resistant weeds and hold field days at those sites.
• We anticipate that each state will conduct a number of different grower and crop advisor focused meetings or workshops to discuss herbicide resistant weed management. Each state will conduct 10 to 20 meetings/workshops 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.

Most farmers and scientists agree that glyphosate combined with glyphosate resistant crops is the most significant technology to become available to farmers in the past 50 years. This technology has revolutionized agriculture and allowed farmers to farm more acres with less equipment and labor. The average farm size has increased and has the number of acres under conservation tillage practices have grown by more than 30%. Widespread adoption of Roundup Ready soybean and corn has led to severe infestations of glyphosate-resistant horseweed throughout the U.S. and large pockets of glyphosate-resistant Palmer amaranth, waterhemp, and giant ragweed.

Current agriculture systems are being compromised by the development of glyphosate-resistant weeds. To date, over twenty-three species have evolved resistance to glyphosate worldwide and at least thirteen of these are found in the U.S. Eight of the thirteen are major threats to soybean production (Palmer amaranth, common waterhemp, common ragweed, giant ragweed, marestail/horseweed, goosegrass, Italian ryegrass, and Johnsongrass).
