When do I put this on the trees that already have Oak Leaf Blister. And how often?
Monterey Garden Phos Systemic Fungicide is not specifically labeled for oak leaf blister but is applied to oaks for soil drench applications at the rate of 1/8 tsp. per gallon of water. Apply each 25 gallons of solution to an area of 100 sq. ft. Follow application with irrigation. Repeat as required. Limit of one application per month.
