What is the amount of Prime Source Chlorothalonil in one gallon of water for spruce tress with rust?

Answer:

Prime Source Chlorothalonil 82.5DF Select does not state a specific rate for rust on spruce trees on the product label. For more information on this, we would recommend contacting the manufacturer (Prime Source) directly at 800-247-8013.
