Brief Project Summary:

Glyphosate-resistant weeds, especially waterhemp and common ragweed, continue to increase in Eastern North Dakota. The objective of this research project is to compare the effectiveness of herbicide programs in a glyphosate-resistant waterhemp and/or common ragweed population utilizing pre-emergence and/or post-emergence herbicides in LibertyLink and Roundup Ready soybean.

Successful completion of this research project will enhance the knowledge of North Dakota soybean producers and improve their profitability. Profitability will be enhanced by reducing soybean yield loss from early season weed competition and protecting future yield goals by limiting or eliminating weed seed production....

Information And Results
Final Project Results

• Weeds can be effectively controlled with Liberty in LL Soybean.
• Glyphosate applied alone and in tank mixes will not control all resistant weeds and increases the selection of multiple-resistant biotypes.
• The use of soil-applied herbicides improved weed control.

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.
