Will Prime Source Chlorothalonil 720 Select control nostoc algae in the lawn and on gravel areas?

Answer:

Prime Source Chlorothalonil 720 Select is not labeled for nostoc algae so would not be recommended.  Nostoc thrives in areas with high phosphorous, compacted soils, and poorly draining areas.  Bonide MossMax RTS would be a better option.  We also found an article here with more information that might be helpful.
