Although it has not yet been confirmed in Whitley County as of the summer of 2013, it has been confirmed in counties that surround Whitley,” said Extension Office officials. “It is perhaps the greatest agronomic weed problem we’ve faced in many years, because most populations are resistant to glyphosate and ALS herbicides, and the weed has tremendous reproductive potential.” Dr. William Johnson, Purdue professor of weed science, will discuss palmer amaranth management strategies, as well as offer an overall weed control update.Finally, John Woodmansee, Extension Educator in Whitley County, will cover strategies to reduce drift.Preregistration is required. Please call the Whitley County Extension office at 260-244-7615 or 260-625-3313 by March 25 to register.
