Select Source Myclo 20EW Fungicide mixing ratio is:
Non-residential turfgrass: 1.0 to 2.4 fl. oz. per 1,000 square feet
Residential turfgrass: 1.2 fl. oz. per 1,000 square feet
Normally 1 gallon mixed solution covers 1000 sq. feet.
Prime Source Myclo 20EW Fungicide is not labeled for any diseases of Eugenia specifically, however there are directions for use on ornamentals of 6-12 oz per 100 gallons of solution for most ornamentals.
Once Prime Source Myclo 20EW Fungicide has been mixed with water the solution is only good for 24 hours. The longer you leave the product in suspended animation the more the water breaks it down & essentially looses its potency.
You will need to discard the leftover mixed solution and mix a new batch for your next treatment in 2 weeks.
