Indiana CCA Conference 2019 Presentation

When we think of weed management in organic crop production systems, often the first thing that comes to mind is steel. However, organic farms that depend upon cultivation alone for weed management may have a tough time of it. In this presentation, we’ll discuss the fundamentals of an ecological approach to integrated weed management in organic production systems, including topics such as:

  • why it pays to know your weeds
  • what the study of weed life cycles tells us about effective management targets
  • spreading opportunities for control throughout the weed life cycle
  • weed seedbanks: how they form, and how to manage them
  • designing effective crop rotations
  • managing soil properties to suppress weeds

Designing and implementing multi-tactic weed management systems for your farm is an investment that will pay considerable dividends over time.

Dr. Adam Davis serves as Professor and Head in the Department of Crop Sciences at the University of Illinois at Urbana-Champaign. Prior to beginning this position in September 2018, Adam worked for 14 years as a Research Ecologist with the USDA-ARS Global Change and Photosynthesis Research Unit, embedded within Crop Sciences on the UIUC campus. He received a B.A. in Biology from Yale University, an M.A.T. in Secondary Science Education from Brown University, an M.S. in Ecology and Environmental Sciences from University of Maine, and a Ph.D. in Crop Production and Physiology (Weed Science) from Iowa State University. Adam's research makes use of both experimental and modeling approaches to solve applied weed ecology problems in field crop production systems. Recent research areas include modeling the evolution and spread of herbicide resistant weeds, developing multi-tactic integrated weed management systems for organic and low-external-input farms, predicting changing distributions of weedy and invasive plant species under global change and conducting risk analysis of bioenergy crop invasion potential.
