Diseases of wax apple include Pestalotiopsis fruit rot ( Pestalotiopsis eugeniae (Thüm.) S. The fruits have a thin, delicate skin and are thus easily susceptible to pest and disease attack. In 2004, Thailand earned US$ 26.5 million from 69,608 tons of wax apple planted over 10,240 ha (Shü et al., 2008). In Thailand, the wax apple fruit is commonly known as chomphu and harvested the year round with a peak during January to March from the cultivars 'Dang Indo', 'Phet Ban Plew', 'Phet Jin Da', 'Phet Nam Pueng', 'Phet Sai Rung', 'Phet Sam Phran', 'Thub Thim Chan', and 'Thun Klao'. (Myrtaceae) is widely grown for its fruits throughout Cambodia, Laos, India, Philippines, Samoa, Sri Lanka, Taiwan, Thailand, and Vietnam (Srisaard, 2003 Vara-Ubol et al., 2006). ![]() Key words: β-tubulin, fruit rot, ITS, neighbor-joining, phylogenetic, tef1. Pathogenicity testing proved that wounding triggers the disease symptoms and thus careful handling of fruits during transport and storage helps to prevent the disease. ![]() samarangensis from other species in the genus. Molecular analysis of the ITS, β-tubulin, and tef1 combined gene sequences distinguish P. Later, the spots enlarged rapidly, became sunken, and resulted in a soft decay of the fruit flesh. Initially small, circular, black, slightly sunken spots developed on fruits. ![]() IVLandcare Research, Private Bag 92170, Auckland, New ZealandĪ new fungal species, Pestalotiopsis samarangensis, was isolated from fruit rot in Syzygium samarangense from markets in Chiang Mai and Chiang Rai provinces, Thailand.
