Effects of humidity regulation on the infection of Botrytis cinerea to tomato

2003

A:PS

High humidity was a primary determinant of the spore germination of B. cinerea, the causal agent of tomato gray mould. At least 80% RH was needed for spore germination, and the highest germination ratio could be obtained when the spores were placed in water drops. At optimum temperature, spores and hyphae could infect the tomato plant to develop softening and rot lesion when RH reached over 85 and 80%, respectively. In one day, sustaining time of high humidity directly influenced the development of tomato gray mould, the pathogen could infect tomato successfully when sustained time of high humidity (RH > 85%) was longer than 8 h.
