This causes lesions, on which [...] this happens faster so the lesions remain smaller. Based on the research that has been done on the influence of climatic conditions on release of ascospores [...] lesions on blossoms, leaves, petioles and fruits and sometimes on twigs and bud scales. The lesions are olive-green. When spores are produced, the lesions
