We are unable to provide a rate as Honor Guard PPZ Fungicide with 14.3% Propiconazole is not labeled to treat entomosporium leaf spot on Hawthorns, it is only listed for rust on them. A better option would be the CuPRO 5000 DF Fungicide, you would use 3 to 5 lbs per acre in 20-50 gallons of water. This comes out to just over 1 ounce (2 TBSP) per 1000 square feet in no less than 1-2 gallons of water per the product label.
