Brief Project Summary:

Controlling resistant weed species is a major problem for farmers. Marestail, waterhemp and palmer amaranth are the most challenging weed species to control. Soybean research funding has gone into examining various methods of weed control, including using electrical charge and grinders. No matter what type of prevention is used to combat weeds, resistance will eventually prevail. The grinder is mounted on the back of a combine and renders weed seed non-viable. The Weed Zapper has a large electrical generator pulled behind a tractor with an electrocution bar mounted on loader arms.

Information And Results
Project Deliverables

Conducting greenhouse screens to confirm or negate what was observed in the field. And if needed, carry out field trials to further confirm or negate. Results will be presented to Missouri producers and technical audiences to emphasize the need to think beyond current chemical control options.

Keep trial going in the same location to better understand the long-­term benefits or costs associated with the added non-chemical control aspects. Additionally, within the next couple of years, this trial site should be an effective visual demonstration at field days for Missouri farmers to look at the impact of combining non­-chemical control options and for further study of all of the potential advantages and disadvantages of narrow windrow burning.

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.
