Dr. Syeda Fatima Manzelat
Abstract
Banana ( Musa paradisiaca) is commonly grown in Jizan province.This study is an attempt to find the mycoflora associated with this giant herb from three different locations of Jizan province. Potato Dextrose agar media was used for culturing and isolation of mycoflora associated with different symptomatic plant parts like the phylloplane , leaf sheath inflorescence ,pseudostem , flower and fruit bunch. The prepared slides are identified by microscopic and macroscopic characteristics . A total of twenty fungal genera belonging to the four classes of fungi were isolated from the three regions Ad Darb , Baysh and Jizan regions of the province .The fungal genera isolated during the study are Pythium ,Syncephalastrum , Perenospora ,Rhizoctonia ,Uredo musae ,Sclerotium , Aspergillus, Botrytis, Epicoccum, Fusarium , Chaetomium , Cladosporium ,Cochliobolus , Colletotrichum, Curvularia , Mycosphaerella ,Nigrospora, Penicillium , Phoma and Verticillium .Herbarium from the symptomatic diseased plant parts is also prepared and preserved .This study reports Black Sigatoka disease caused by Mycosphaerella from all the three locations of study whereas Anthracnose caused by Colletotrichum which is a major disease of Banana is absent in Baysh and Jizan regions. Uredo musae the causal phytopathogen is restricted only to Ad Darb region. Panama disease or Banana Wilt caused by Fusarium and Cigar end rot caused by Verticillium are the other diseases reported from the three regions of the province during this study. This study will help in effective monitoring and control of the phytopathogens of this valuable and nutritious fruit bearing plant. Key words: Banana , Mycoflora, Jizan , Saudi Arabia.
