Brief Project Summary:

Weeds have a detrimental impact on crop yields and quality in soybean crop. Non-selective glyphosate POST herbicide has been used extensively on soybean fields to provide a convenient, economical and effective way to help manage weeds. On the other hand, the widespread adoption of glyphosate-resistant crops around the field has resulted in the evolution of several-glyphosate-resistant weed biotypes. Glyphosate -resistant weeds populations have been identified in ND in fields where Roundup Ready® soybean had been grown continuously for as many as 7 or 8 years and glyphosate was used exclusively. Thus, identification and intensive scouting of glyphosate-resistant weeds such as waterhemp,...

Information And Results
Project Deliverables

We anticipate developing an algorithm to identify glyphosate-resistant weeds in the field. Project personnel will improve the accuracy of discriminating weeds types and develop a method for identifying weeds in the field to develop weed maps by remote sensing. Remote sensing will provide a cheaper, more efficient method of mapping infestations than ground surveys. Results of this work will be presented at conferences, grower meetings, field day tours and NDSU website. The work will also be submitted to peer-reviewed journals for publication.

Final Project Results

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.
