What are the mixing directions when using a backpack sprayer to apply Prime Source Chlorothalonil 82.5DF Select?

I battle brown patch on my St. Augustine yard. I want to alternate Chlorothalonil 82.5DF with other treatments. I'm guessing 1 oz per gallon of water when mixing for a backpack sprayer. Is that about the correct amount? I realize it depends on several factors. Also can I mix in an insecticide such as Talstar or Bilfen when spraying? Thank you for your assistance.

Answer:

To treat brown patch using Prime Source Chlorothalonil 82.5DF Select on turfgrass, you would use 1.8 - 3.25 oz per 1,000 square feet. Using 1 oz per gallon of water would be fine if that gallon is only covering about 300-500 square feet. Typically 1 gallon of solution covers 1,000 square feet in a hand pump sprayer.
