Identify weeds fast with new online tool

Florida weeds run aplenty, especially in the summer. Getting rid of weeds starts with proper identification, and UF/IFAS experts developed an online tool that organizes weeds by flower color for fast identification.

The tool helps identify 130 of the most common weeds found in Florida.

“If you don’t take the time to identify the weed first, often times you may treat it incorrectly,” said Chris Marble, associate professor of environmental horticulture at the UF/IFAS Mid-Florida Research and Education Center. “Applying the wrong herbicide or applying incorrectly can cause irreversible damage to a landscape and sometimes only the weed you were trying to eliminate will remain.”

This new online tool developed by Annette Chandler, a biological scientist at UF/IFAS MREC, and helps users identify weeds in their landscape and develop a plan of attack with management recommendations from Marble.

To make best use of the resources, follow these steps:

  • Visit the online identification tool and select the flower color of the weed in question.
  • Once identified, select the accompanying video linked on the weed’s landing page and watch for more information on the weed and management strategies.
  • In some cases, there will be an Ask IFAS document with further information.

“Florida’s weed pressure is really high year-round,” said Marble. “We don’t get freezes very often to kill them off. In most places a summer annual is only going to be a problem five to six months out of the year. But here in Florida, it still germinates at my house in Winter Park in mid-December. It never really stops here. There is heavy weed pressure all the time.”
