What to do about yellow fields

Glenn Nice, Weed Diagnostician, Botany & Plant Pathology, Purdue University

We are getting many phone calls about Indiana’s yellow spring. The plant that turns Indiana yellow every year is cressleaf groundsel, also known as butterweed (Packera glabella, formerly Senecio glabella). Below are two articles concerning this plant and how to control it. We also invite you to visit the Purdue Weed Science page for more information regarding weed management in Indiana ( http://www.btny.purdue.edu/weedscience/ ).
