Fact Sheet FS1341
Yellow nutsedge (Cyperus esculentus) is a persistent weed commonly found in irrigated production fields, landscapes, and turf. Its sturdy leaves and angled stems are strong enough to puncture plastic and woven mulches. Reproduction through rhizomes and nutlet tubers allows for rapid reproduction and spread throughout fields. Understanding the life cycle and biology of nutsedge are key to figuring out the best options for control in your fields.
Nutsedge is a grass-like perennial that has three-angled stems, long grass-like leaves, and is yellowish-green in color. Characteristics include:
Control of nutsedge in production areas can be a multi-year process that involves several strategies for control. Once nutsedge is found on the farm, control measures should be identified and implemented. Organic and no-spray farming operations will need to rely on well-timed cultivation and strategic planting to compete with the weed infestation.
Farm Decision Tool
Yellow nutsedge management is a long-term process for farms not relying on herbicides or fumigants. Identification of existing nutsedge populations on the farm and reflection on your activities and how they impact these populations is the first step to developing a management plan. Use the charts below to identify your nutsedge populations, your current management methods, and to develop a plan of action to eradicate nutsedge from production areas.
