Abstract:

Surveys for plant diseases caused by fungal pathogens in 2021 led to the observation of leaf senescence on Zamia furfuraceae plant grown as ornament in City Housing Society, Gujranwala, Punjab, Pakistan. Infected leaves appeared to have dark brown patches on their surfaces (both axial and abaxial), originated by white cottony spots. The infection showed different patterns of spot formation causing necrosis that ultimately covered the entire leaf. Zamia furfuraceae is an endemic plant of Mexican origin. It is the second most traded cycad in the world horticulture market for its beauty. The illegitimate transportation out of the natural habitat has led the plant to be endangered. The causative agents for the disease were isolated by taking small pieces or scratches of infected leaf from the necrotic patch on a slide with 5% KOH as mounting media. The causative agent for the disease was identified as Trichothecium luteum, based on morphological and anatomical observations. The species is generally found in association with fruit spoilage in fruit-bearing plants (Sharma et al., 2014). This research paper claims to report a new host for the species as well as first report of T. luteum from Pakistan.
