A theoretical model (Prot. Ecol. 5:103-125) was the framework of a study of factors affecting the number of Venturia inaequalis ascospores per m('2) orchard floor per season (PAD) in New Hampshire apple orchards. PAD was calculated as the product of scab lesions per m('2) leaf tissue at leaf fall, pseudothecia per lesion, asci per pseudothecium, the proportion of the orchard floor covered by leaf litter at bud break, and ascospores per ascus. Disease incidence and the proportion of lesions that formed mature ascocarps were strongly correlated; lesion fertility was directly proportional to disease incidence at leaf fall. Most lesions from …
