When is the best time to apply Fung-onil Fungicide on a black cherry tree with brown spots on the leaves?

The tree is about 18 feet tall how much should be apply. How often. Once a a week ????


If you consume the cherries from the tree, then you can use Fung-onil Multi Purpose Fungicide Concentrate at leaf fall in late autumn for leaf curl. For other listed diseases, apply at budbreak or popcorn, then full bloom to petal fall, and at shuck split to prevent infections on young fruit, per the product label. You will use 3 ¾ tsp per 4 gallons of water, generally to treat about 200 square feet. If you need a product to use while there is still fruit on the tree, then you may want to consider Fertilome Triple Action.
