Abstract
Abstract Field plots of strawberry ( Fragaria × ananassa Duch cv. Chandler) were exposed to two 1-hr nighttime simulated fog episodes per week at specific acidities from pH 1.6 to 3.2, or no fog. Small, distinct, irregularly shaped, rust-colored lesions developed on foliage and fruit after a single 1-hr exposure to acidic fog at low pH. Fog episodes at pH 1.6 resulted in death of the plants after 8 weeks. Strawberries tolerated short-term exposure to acidic fog at pH 2.0 or higher, with little or no negative effect on growth, yield, or fruit soluble solids. However, calyx injury from acidic fog reduced marketability at pH levels up to 2.8. ‘Douglas’, ‘Chandler’, ‘Selva’, ‘Parker’, and ‘Soque!’ differed in magnitude of response to acidic fog in greenhouse exposures.
