Seasonal Incidence of Fungi in Symptomless Cranberry Leaves and Fruit Treated with Fungicides During Bloom

In 1987 and 1988, leaves and fruit were collected at 2-wk intervals for 20 wk from replicated plots at two commercial cranberry (cultivar Searles) marshes in central Wisconsin. Leaves were collected from budbreak, and berries were collected from 8 and 6 wk after budbreak in 1987 and 1988, respectively, until harvest. Beginning during bloom, captafol, chlorothalonil, and mancozeb were applied to plots three times at 14-day intervals to manage postharvest storage rots. Control plots received no fungicide. Fungi were isolated from surface-disinfested, symptomless leaves and berries on all sampling dates in both years (...)
