Do read past cranberry school proceedings. The 1999 school focused on cranberry diseases. DON Ts Don t expect miracles from fungicides. Orbit for control of cottonball has generally been good, but fungicide performance against other diseases has ranged from fair to poor. Don t overdo it with nitrogen.
Succulent tissue is generally more susceptible to disease.
Dense, lush vines retain moisture that favors fungal growth. Don t go below the 4 oz. rate when using Orbit. Lower rates won t control disease and may ultimately lead to fungicide-resistant pathogen populations. Don t let a cottonball-infested bed go unharvested. It may not be profitable to harvest such a bed when the price of cranberries is low.
