How much Fung-onil Multi Purpose Fungicide Concentrate should I use in a tank sprayer per gallon of water?

How often should I apply this? Black Eyed Susan has brown leaf spotting. I bought Fung-onil.


For ornamental gardens including flowers, you would use 2 1/4 tsp of Fung-onil Concentrate per gallon of water, or 3 tablespoons per 4 gallons of water. Repeat applications at 7 to 14 day intervals until conditions re no longer favorable for disease. Keep in mind that applications made during bloom may damage flowers. Please see the product label for complete application directions.
