Brief Project Summary:

The spread of herbicide-resistant Palmer amaranth (Amaranthus palmeri) and waterhemp (Amaranthus tuberculatus) across Kentucky during the past few years creates a unique challenge for soybean producers. The goal of this research is to characterize and evaluate control options to help manage and mitigate the spread of these species. This research will improve our understanding and knowledge for integrating a new generation of soybean varieties that are tolerant to glyphosate, dicamba, and glufosinate (three different herbicide mode of action groups) into a planned weed control approach that can be used to combat these troublesome Amaranthus species. The ultimate goal is to enable soybean...

Information And Results
Project Deliverables

This research can help improve our knowledge and understanding on how to integrate new herbicide tolerant crop varieties with control tactics to control herbicide-resistant populations of Palmer amaranth and waterhemp. By having this information, growers and crop advisors will be in a better position to make informed decisions for developing and implementing weed control programs to mitigate and manage herbicide resistant weeds. Information will be extended to soybean producers, crop consultants, extension agents, agricultural retailers, and industry representatives through various mechanisms including newsletters, meetings and field days.

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.
