Abstract  

In 2023, a fungus was isolated from rotting navel orange (Citrus sinensis), which presented typical fruit rot disease symptoms for the first time in Ismailia governorate East of Egypt. The pathogen was isolated and identified as Scopulariopsis brevicaulis (telemorph: Microascus brevicaulis). A pathogenicity test was carried out to fulfil Koch’s postulates. The pathogen enters the orange fruit and cause fruit rot through wounds. The fungus has pathogenic effects on other crops, such as Mandarin (Citrus reticulata), Lemon (Citrus limon), Mango (Mangiferaindica), Banana (Musa acuminata), Peach (Prunus persica), Plum (Prunus simonii), Pear (Pyrus communis), Apple (Malus sp.), Tomata (Solanum lycopersicum), Pepper (Capsicum annuum), Eggplant (Solanum melongena) and Guava (Psidium guajava). Symptoms vary in severity depending on the crop species. According to the available literature, this is the first record of orange fruit rot on orange in Egypt.
