Reducing Risk in Soybean Production by Building Sustainability in the Best Management Practices for Herbicide-Resistant Weeds

Grants and Contracts Details


STATEMENT OF WORK (University of Kentucky 4-26-22) The funding from this grant will be used to support research efforts to promote stewardship of management of herbicide-resistant weeds in Kentucky. Palmer amaranth(Amaranthus palmeri), waterhemp (Amaranthus rudis), and horseweed (Conyza canadensis), are examples of glyphosate resistant weeds that will be targeted. In addition, populations of Amaranthus species have been identified in Kentucky to be resistant to herbicides within the PPO inhibitor mode of action group. Field technicians will assist Extension weed scientists in conducting field research trials to collect data pertaining to planting into green cover crops with early planted soybean to mitigate early season Palmer amaranth and waterhemp. An ongoing project collecting temperature inversion data in a lowland versus upland location in western KY will continue. Additionally the University of Kentucky Extension weed science team will collaborate on a metribuzin rate research project for continued efforts to mitigate herbicide resistant weeds for a second year and initiate an initial year of a metribuzin paired residual trial in early season soybean. The collaborative effort of the project will see Kentucky data being culminated with other researcher’s data to help develop BMP (Best Management Practices) for control of these troublesome weeds utilizing the newest soybean traits. Kentucky data will also be disseminated within the state to target audiences of growers, Extension agents, crop consultants, private and commercial pesticide applicators, and other agricultural industry representatives.
