Have sprayed on a 3 year oak tree - already seeing a difference, but how often should I spray - late August/September....
The product label for Fung-onil Multi Purpose Fungicide Concentrate states: Repeat applications at 7 to 14 day intervals until conditions are no longer favorable for disease. During periods when conditions favor severe disease incidence, generally cloudy or wet weather, apply this product at 7 day intervals.
