Jamie Patton, UW-Madison Nutrient and Pest Management Program
With the increasing prevalence of herbicide resistant weeds across the state, it is imperative to stop the accidental spread of weed seeds from field-to-field through contaminated equipment. As of December 2018, there were 20 unique cases (weed species by herbicide site of action) of herbicide resistance confirmed in Wisconsin, including 13 weed species with evolved resistance to one or more herbicide sites of action. With fall quickly approaching, now is the time to be gearing up to stop the spread of weed seeds through harvest activities.
Join us on August 12th at Seed Concepts, Inc (N3065 WI-32, Pulaski, WI) for a hands-on Combine Cleaning Clinic. This free event, hosted by Seed Concepts, Marinette and Oconto County Extension, and UW-Madison College of Agriculture and Life Science and Nutrient and Pest Management Program, will run from 9:30 am to 12:30 pm. A light lunch will be provided.
Dr. Rodrigo Werle, Extension Cropping Systems Weed Specialist, and Nick Arneson, UW-Madison Outreach Specialist, will discuss weed seed production, viability, and the spread of common weeds. They will also present the results of their recent waterhemp and giant ragweed studies. Dan Smith, UW-Madison Nutrient and Pest Management Outreach Specialist, will then walk participants through the steps to properly clean a combine to limit the spread of weed seeds.
