Weed Management Principles in Commercial Vegetable Production

Figure 1.  Wild radish interference in sweet corn Credit: P. J. DittmarWeeds compete with vegetable crops for light, water, and nutrients. This competition decreases plant vigor, yield, and crop quality. They interfere with hand harvest and can complicate or prevent machine harvest. Weeds also serve as alternative hosts to diseases, viruses, and nematodes. A successful weed management program will incorporate multiple control practices with preventative, cultural, biological, mechanical, and chemical methods.

Biology and Management of Common Purslane in Fruiting Vegetables, Cucurbits, and Strawberries

Figure 1.  Common purslane growth in a fallow field. Note fleshy stems and leaves with no hairs. Credit: Nathan BoydPurslane occurs throughout the year in Florida. It produces thousands of seeds per plant, which germinate readily, but can also persist in the soil for up to 15 years. Vegetative shoot fragments can survive on the soil surface for extended periods of time, then re-root when exposed to moisture and can even flower and produce seeds after they have been pulled from the soil. This characteristic enables purslane to persist and spread following cultivation. This 4-page fact sheet was written by Nathan S. Boyd, Andrew W. MacRae, Rick Kelly, and Ixchel M. Hernandez, and published by the UF Department of Horticultural Sciences, July 2014.
