What is the setting rate of Prime Source Chlorothalonil 82.5 DF when using an Ortho Dial-n-spray?

I would be treating tall fescue in a residential lawn for brown spot control.


Prime Source Chlorothalonil 82.5 DF Select is not for use in any type of hose end applicator. It must be used in a tank sprayer and per the product label for brown patch is mixed at 1.82 to 3.25 ounces per 1000 sq/ft and can be reapplied every 7-14 days to maintain control of the disease and prevent it.
