This webinar was recorded on February 17, 2015.
This webinar will provide an introduction to the concept of weed management with air-propelled abrasive grits, or "weed blasting", in organic cropping systems. We will present information about the design of the first abrasive-grit applicator and initial field studies in corn, soybean, tomato, and pepper crops. Lastly, we will outline ongoing and future research objectives recently funded by the National Institute of Food and Agriculture Organic Research and Extension Initiative.
