Abstract

During a disease survey of infected plants in Gujranwala, Punjab, Pakistan, untypical, irregular, dark brown to black necrotic patches on Yucca aloifolia were observed, causing leaf tip die back. Stereomicroscopic examination shows white to pinkish white mass giving powdery mildew appearance over the surface. Morpho-anatomical characterization identified the pathogen belong to the genus Trichothecium, as Trichohecium roseum. Description and illustration of the identified species are presented. Previously no work has been done on Y. aloifolia from Pakistan. To the best of our knowledge, this is the first report of T. roseum causing leaf die-back on an ornamental, Yucca aloifolia in Pakistan. It is a new host report of T. roseum for Pakistan and worldwide. A key to Pakistani species of genus Trichothecium is given in this paper.
