Hartney says many people are opposed …
UF Researchers Developing Combinations of Fumigants to Fight Nutsedge
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 …

Cutting Costs With Smart Sprayers
By Yiannis Ampatzidis Traditional broadcast sprayers usually treat the entire field to control pest populations, potentially resulting in unnecessary application to areas that do not require treatment. These sprayers apply agrochemicals uniformly, even though distribution of weeds is typically patchy. This results in wastage of valuable compounds, increased costs, crop damage risk, pest resistance to chemicals, environmental pollution and contamination …
Controlling Purple Nutsedge in Tomatoes
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 …
