Just one tuber can generate hundreds of shoots, forming a dense patch that can span …
By Clint Thompson Nutsedge is one of the most devastating and frustrating pests that Southeast vegetable producers encounter every year, but it can be managed more effectively. Growers must be dedicated to implementing a year-round management system and not just one that’s effective during a specific production season. Nutsedge is a destructive weed that can overwhelm a cropping system and …
By Clint Thompson One of the main weed threats to vegetable production requires a year-round management strategy, not just when the crop is in season. Stanley Culpepper, University of Georgia (UGA) Cooperative Extension weed specialist, discussed the nutsedge management during the Southeast Regional Fruit and Vegetable Conference in Savannah, Georgia. “Nutsedge is always a problem in vegetable production. It’s such …
By Clint Thompson There are ways to control nutsedge during the upcoming fallow period. Cover crops are not an effective solution, however. Nathan Boyd, University of Florida (UF) associate center director and associate professor of horticulture/weed science at the Gulf Coast Research and Education Center, discusses why cover crops are not recommended to manage nutsedge, which can grow up to …
By Clint Thompson Nutsedge may not be the most problematic weed Florida vegetable and specialty crop producers encounter every year, but it is a problem. Nutsedge is most concerning because it is the only weed to puncture through plastic mulch, says Nathan Boyd, University of Florida Associate Center Director and Associate Professor of Horticulture/Weed Science at the Gulf Coast Research …
By Clint Thompson University of Georgia Cooperative Extension weed specialist Stanley Culpepper encourages vegetable growers to diversify their management programs against nutsedge. This protects against potential resistance and provides adequate control. “In general, I would say with our guys, I’m not overly concerned because our fields with our most nutsedge, they get fumigation, they get tillage and they get herbicides,” …

By Peter Dittmar All weeds are problematic in blueberry production because they compete for water and nutrients, hinder harvest crews and decrease yields. One of the most problematic weeds in blueberry is nutsedge (Figure 1). The two species of perennial nutsedge in Florida are yellow (Cyperus esculentus) and purple nutsedge (C. rotundus). These weeds are difficult to control because of …
By Karla Arboleda Researchers at the University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) are developing fumigant combinations to fight nutsedge. Nathan Boyd, an associate professor of horticulture at UF/IFAS, said options are limited when trying to control the weed. “Nutsedge is a problem because it’s the only weed that punctures the plastic mulch that we use,” Boyd …
Purple nutsedge can be a tough nut to crack for many tomato growers. Nathan Boyd, weed scientist at the University of Florida’s Gulf Coast Research and Education Center (GCREC), recently completed herbicide trials examining whether pre-emergent or post-emergent herbicides work better in controlling purple nutsedge in tomatoes. The trials took place at the GCREC in Wimauma. Purple nutsedge can be …
