On January 8, the program will feature Dr. Mark Loux, OSU Extension State Specialist in Weed Science speaking on No Pigweed Left Behind. Western Ohio and other areas of the state have seen the recent spread of waterhemp and Palmer amaranth beginning to infest fields. These pigweeds are currently resistant to three herbicide modes of action in Ohio and because they are genetically diverse, have the ability to become resistant to other chemicals in a short period of time. Once they do, they become difficult and expensive to control and can rapidly decrease the profitability of a field. The presentation at the Conservation Tillage Club breakfast will focus on how to prevent the spread of these weeds, as well as how to manage them once they do show their presence in a field. Dr. Loux’s presentation will also address other resistant weeds that are difficult to control.
