LSU AgCenter devotes web page to giant salvinia


LSU’s AgCenter has a new resource to help educate the public about the invasive weed, giant salvinia.

The website,, looks at the problem of salvinia and control methods. Images and maps show how the aquatic plant has spread across Louisiana waterways, including Lake Bistineau.

 “The purpose of the website is to have a central hub for information about giant salvinia,” LSU AgCenter entomologist Rodrigo Diaz said. “We have compiled practical information about the biological control program of giant salvinia in Louisiana.”

Diaz is conducting research on the salvinia weevil, an insect that feeds on the plant and has been shown to control it.

This website includes information on how to recognize giant salvinia, its effects on aquatic habitats and how to use salvinia weevils to manage this problem.

“Managing giant salvinia with biological control requires monitoring the population of weevils and salvinia conditions. We hope this website will be useful not only for plant managers but also people who enjoy wetlands,” Diaz said.
