Algae Management on Putting Greens
John Kaminski, Ph.D.
infestation on closely mown putting greens continues to be difficult to manage.
While applications of various fungicides, such as chlorothalonil and mancozeb,
have been shown to suppress algae, these products must be applied on relatively
short intervals prior to the appearance of symptoms, and their efficacy varies.
Further complicating the use of fungicides is the exclusion of chlorothalonil
in individual regions of the U.S. In areas where chlorothalonil use remains
legal, new label restrictions on the total amount of product that can be
applied and increased time between application intervals may drastically limit
the ability to control algae over the course of an entire season.
webcast, John Kaminski, Ph.D., presents recent work that has shown algae
suppression is possible with alternative strategies involving the application
of phosphites products, selection of proper nitrogen sources, and potentially
through the use of wetting agents. Kaminiski also addresses the current
literature and discuss some of the recent findings of the GCSAA-funded algae
