Brief Project Summary:

Enlist technology, also known as 2,4-D Tolerant (ET) soybeans, is very new technology and will likely be planted in Nebraska (and elsewhere) on a very limited acres in 2018 (contract production only). During these early adoption stages, the majority of soybeans will be the non-ET varieties, therefore there is an obvious concern that the use of 2,4-D based herbicides will result in unintended drift. The herbicide 2,4-D is not as volatile as dicamba, but it has also tendency not only to drift with any air movements (even slight wind), it can also move off the sprayed site during air temperature inversions. Therefore, there is a need to establish baseline data in Nebraska on potential injury...

Information And Results
Project Deliverables

1. This project will directly show the level of soybean sensitivity to micro rates of 2,4-D (EnlistDuo) with potential effects on yields of non-ET soybeans.
2. Our data will provide information needed for educational materials about the critical need for proper herbicide application procedures and sprayer cleaning in order to reduce 2,4-D’s off-target movement.
3. Ultimate goal is to provide help in preventing potential drift cases and disputes among neighbors.
4. In addition, results from this study will be helpful to Nebraska legislature and lawmakers to develop possible guidelines related to distance needed between the Enlist soybean and neighboring sensitive crops or acreages. Results will also help Dr. Knezevic explain potential issues as he was asked to testify in front of Nebraska State Legislature, as the state might tighten the regulations on use of 2,4-D.

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.
