Can Clearys 3336F be used by drench method to treat powdery mildew on dogwood trees?
Trees had powdery mildew last year. I want to treat them before leaf out this year.
Clearys 3336F is labeled for powdery mildew but would be applied as a foliar spray only when the disease first appears and repeat every 7-14 days during disease period per the product label. We are not able to find any soil drench product for this disease.
