Management of Hydrilla Dependant on Biotype, Experts Say

Posted April 2014

Homeowners, boaters, fisherman, and other recreational users deal with a familiar looking problem weed in water bodies from Florida to Maine.  A resident on a lake in New York State would likely call the whirled leafed invader the same as a farmer in the bayou.  Hydrilla,  a nasty invader throughout many water bodies of the United States may look similar across state lines, but researchers with the Aquatic Ecosystem Research Facility in Lewisville, TX show just how different the plant, and it’s subsequent management can be from one state to the next.Hydrilla vertcillata.

Weed research has positive flow-on effects

Posted October 2012
Victorian scientists are working on a solution to control aquatic weeds that block irrigation channels. Scientists … are testing a potential new herbicide to wipe out submerged aquatic weeds. DPI Senior Research Scientist Tony Dugdale said efficient water delivery was of critical importance to irrigators, farmers and the community. “When these weeds infest irrigation channels, the hydraulic capacity of the channels is reduced and the delivery of water becomes compromised,” Dr Dugdale said. “This ultimately leads to reduced water delivery to irrigators.”
