The top two weeds farmers in Wisconsin are most concerned with are giant ragweed and waterhemp according to a 2018 Wisconsin Cropping Systems Weed Science Survey. These troublesome weeds have been tested to be herbicide resistant, which means that one mode of action for controlling the weed doesn’t work anymore. These weeds are often spread during harvest of the commodity crop they are growing in.
On Thursday, August 30, farmers and custom operators are invited to a combine cleaning clinic held at Tim and Bryon Feller’s farmstead at N6437 Schneeberger Road, Monticello. Dr. Rodrigo Werle, an Extension Weed Scientist from UW-Madison, will help producers understand the many ways seeds are spread, the different amounts of seed each weed produces and the length of time seeds are viable in the ground. Dan Smith, Southwest Regional Specialist for the Nutrient and Pest Management Program will show the steps needed to clean combines. Cleaning combines is a good way to stop the spread of weed seeds.
The clinic will start at 10 AM and should conclude around noon. The event is free and open to the public. For more information contact Tonya Gratz with the Green County Land and Water Conservation Department at 608-325-4195 extension 121.
