Abstract
Perithecial strains of G. cingulata were detected in 5 apple orchards in North Carolina [USA]. The relative frequency of perithecial strains varied from orchard to orchard. Airborne G. cingulata ascospores were detected within an apple orchard and within 3 m of both naturally and artificially infected apple branches. Ascospore catches were maximal during the evening and early morning, especially on and after rainy days.
