Brief Project Summary:

Broadscale damage to soybean occurred in North Dakota this season that was consistent with symptoms of exposure to dicamba which was used more extensively this season with adoption of dicamba-resistant soybean (Xtend technology). In 2016, a drift trial was conducted to evaluate off-target movement of dicamba to non-Xtend soybean. Seed was collected from various areas around nontreated plots and plots that received dicamba treatment. In preliminary observation, progeny seedlings demonstrated reduced germination and growth.
Our current project goal is to evaluate seed characteristics and seedling vigor of these soybean samples. Quantifying the dicamba concentration of the seed will be...

Project Deliverables

Under Goal 1, the preliminary observation should be confirmed and provide the extent of effect for several parameters. This will help prioritize future work. Goal 2 will identify viable methods of separating the seeds with less favorable profile. These methods will need to be reviewed by the seed and commodity processors to determine feasibility of implementation. A success in Goal 3 will confirm dicamba residue is not illegal, but further, strong correlation between dicamba concentration and seed/seedling response would be a strong diagnostic tool in evaluating future seed lots.

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.
