Microorganism may provide key to combating giant salvinia throughout Louisiana
Date:11/19/2009

It has had a significant impact the property and safety of residents in low-lying or shoreline areas as well. An unusually wet summer and early fall in north Louisiana has produced flooding and new breeding grounds for giant salvinia.

Preliminary tests show that even one application of the bioherbicide with an adjuvant can drastically reduce the scourge in as few as ten days.

"Dr. Walker has been one of our most prolific inventors," said Dr. Les Guice, Louisiana Tech's vice president for research and development. "This discovery is great evidence of how his innovative research is addressing a major problem in the State but has potential for much broader applications."

Pilot-scale studies are planned at Lake Bistineau to assess the feasibility for development of the microbe as a bioherbicide. These studies will be focused on maximizing herbicidal activity, determination of the long-term effectiveness of treatments, production costs, and integration of the microbe with other control measures.

While the initial results of the research are encouraging, project leaders say the study is still in the early stages of development.
