Abstract

Pink mold rot of tomato occurred very severly on tomato farm in Paju, Gyounggi Province, Korea, in July 2005. The infected fruits were dropped and abandoned and the symptoms were similar to calcium deficient tomatoes. But symptom was a slight water-soaked area on or near the blossom end of the fruit and firm greyish-brown lesions were most found at the blossom-end of affected fruits. lesions caused by the pink mold fungus possess a water soaked margin and rise to characteristic orange-pink spores. Also when the diseased tomato was cut, the inside of tomatoes showed completely rotted with pink mold. The causal fungus was identified as Trichothecium roseum based on mycological characteristics. This is the first report of T. roseum infecting greenhouse tomatoes in Korea.
