I frequently use herbicides and algaecides in my line of work. Having attended college and graduate school to be an Ecologist, it isn’t something I thought I would do very often, but with the frequency of environmental problems that involve invasive flora, nuisance aquatic weeds and potentially-toxic algae, EPA-registered herbicides and algaecides are an invaluable tool. There are, however, times when their use is impractical, imprudent, illegal or impossible. Maybe the HOA or property manager prefers that herbicides not be applied to nearby waters. Perhaps the regulatory bodies in a given area aren’t permitting the use of certain products. Whatever the reason, sometimes this option just isn’t on the table. But how do we effectively manage algae and aquatic weeds without herbicides and algaecides?
I employ a simple concept that I call the algae triangle, though it works for all forms of vegetation.
