Abstract:

Plumeria (common name Frangipani) is a genus of flowering plants in the dogbane family, Apocynaceae., planted commonly on roadsides, gardens in most of the places of Gurgaon, Haryana for its beautiful fragrant flowers. A survey of young plantations of various regions of Gurgaon revealed that this plant was seriously infected by a rust fungus Coleosporium sp, which later leading to drying and death of the foliage. The infected leaves show numerous tiny, raised, bright orange yellow, rusty pustules on the adaxial (upper)surface of the leaf thus reducing the available photosynthetic area of the leaf. The diameter of most of the rust pustules ranged between 0.5-3.0 mm. Symptoms were absent in the stem or flowers. Microscopic studies indicated the presence of uredium, formed from the  extending mycelium in a crosswise direction and emerged through ruptured lower epidermis. No other fruiting structures, telium, aecium or spermatium were  found to be present. Both mature and young leaves were found to get equally infected by  the pathogen.   Severe infection of rust often resulted in chlorosis, necrosis and premature leaf fall. This rust is reported for the first time from Gurgaon region of  Haryana state
