Selection and orchard testing of antagonists suppressing conidia production of the apple scab pathogen Venturia inaequalis [PDF]

open access: yes, 2009
Apple scab caused by Venturia inaequalis is a major disease in apple production. Epidemics in spring are initiated by ascospores produced on overwintering leaves whereas epidemics during summer are driven by conidia produced on apple leaves by biotrophic
