Grace Smith, Undergraduate in Molecular and Cellular Biology Sonja Birthisel, PhD Student in Ecology and Environmental Sciences Eric R. Gallandt, Professor of Weed Ecology and Management A soil microbiome consists of tiny organisms such as bacteria, archaea, fungi, and protists that impact plant life. Beneficial microbes decompose organic molecules, rendering them usable by plants and […]

Sonja Birthisel, PhD Student in Ecology and Environmental Sciences Eric R. Gallandt, Professor of Weed Ecology and Management Solarization is the practice of using clear plastic mulches to trap solar energy, heating soils to temperatures lethal to pests including weeds. Solarization is nothing new; it has been researched and used by growers extensively since the […]
Read moreA simple tool to explore alternative weed management strategies
Bryan Brown, Ph.D. Candidate Eric Gallandt, Professor of Weed Ecology and Management Weed management philosophies and employed strategies have inherent tradeoffs. A surprising result from our field studies conducted in organic onion was the impressive performance of zero seed rain and mulch-based strategies, which performed better than expected even in the first year of […]
Read moreA Comparison of Organic Weed Management Strategies in Onions
Bryan Brown, Ph.D. Student, and Eric Gallandt, Associate Professor What’s your strategy for managing weeds? Cultivate until the crop is large enough to tolerate late-emerging weeds, sometimes returning to harvest from a dense patch of weeds? Cultivate season long and pull any mature weeds as part of a longer-term strategy to prevent weed seed rain and make […]

“Rotation of crops…is the most effective means yet devised for keeping land free of weeds. No other method of weed control, mechanical, chemical, or biological, is so economical or so easily practiced as a well-arranged sequence of tillage and cropping.” — C.E. Leighty. 1938 Yearbook of Agriculture Diversity is key. Dissimilar crop species with disparate […]
