Water Hyacinth Control

Worst we've seen in 30 years. Lack of spraying by Wildlife and Fisheries in the canals and bayous, high water, and the warm winter has them healthy and spreading rapidly everywhere.

Don't think an airboat going to be as effective as a plane at this point. I use a guy named Merlin for airboat application. He's got a buddy that does the ultra light application.

OP, I'd wait until August, you're just opening up real estate for the salvania. Besides, we're due a storm and if your neighbor doesn't spray you may have to do it twice.

Have you considered mechanical extraction instead of poison. There's a guy in Port Barre named David Bertrand that does a fantastic job. You can youtube or google him to see video or images.
