The Ohio State University Weed Lab Image Archive

Our research and extension program is all about helping fruit and vegetable farmers, consultants and extension specialists do a better job of managing weeds. We conduct practical research that brings new weed control technology to the farm, and incorporates new knowledge about weed biology and the agroecosystem. We develop and provide educational programs and curriculum to help our clients become better weed managers. We train students who will become the scientists, educators, extension specialists and farmers of tomorrow. These are images taken by students and staff while working in the Weed Workshop.
