Bonide Mancozeb Flowable with Zinc Concentrate is not labeled to treat for leaf blotch. We would recommend using a product such as Garden Tech Daconil Fungicide Concentrate which is specifically labeled for leaf blotch. You will mix 2 1/4 tsp per gallon of water or 3 tbsp per 4 gallons of water, and spray foliage to the point of runoff. You want to apply this as spring bud break for the best results.
