This would depend on what disease(s) you are targeting.

Contact fungicides offer the longest protection. Daconil (chlorothalonil) for Powdery Mildew. Use Mancozeb for Downey Mildew.

Use a contact fungicide in rotation with at least 1 systemic. Nova/Eagle (myclobutinyl) is the best for Powdery Mildew according to the latest data from Cornell.

Thiophanate-methyl is best for folks who have encountered fusarium or rhizoctonia & it also controls PM.

Lighter than the light rates applied more often (5-7 days) is easier on the plants & keeps the tips from frying.
