Time to Treat the Wid Celery
I can't believe it's already August! Where is the summer going? With all the hot, sunny and calm weather we have been experiencing throughout July, aquatic vascular plant control in the lakes has been a challenge to say the least. The final step in out aquatic vascular plant control for the 2005 season will be the Vallisneria americana (Wild Celery) treatment. Please refer to the previous Blog entitled "Wild Celery is Driving Us Wild" for more information on this native vascular aquatic plant. Working with our herbicide applicator, Norm Zion of Aquatic Nuisance Control, we will be treating the known Vallisneria trouble spots with (3) different experimental concentrations of a chelated copper algaecide. We are using a copper based algaecide because contact herbicides are not effective at selective control of Vallisneria. Additionally, there are no water use restrictions when using this family of chemicals. This experimental approach of using an algaecide was recommended to us by nationally renowned aquatic plant control expert, Bill Haller of the University of Florida. The above map details areas that will be treated and the experimental concentrations that will be applied. This treatment is experimental. There is no textbook cure for alleviating nuisance symptoms created by this native plant. By applying at three different concentrations, we will have the opportunity to evaluate achieved level of control. As time goes by, our ability to control native nuisance plants will evolve.

Your Lake Managers,
Joel Steenstra and Tom Krueger
