摘要：Phytopathogenic bacteria and fungi utilize the vegetables and plant cells as privileged food source and cause devastation under appropriate environmental conditions. In the present study, investigation deals with the isolation and identification of the phytopathogens from diseased vegetables in the fields of District Kohat, Khyber PakhtunKhwa Pakistan. A total of 54 vegetable samples of Allium cepa (Onion), Capsicum frutescens (Green Chili), Hibiscus esculenta (Okra), Luffa acutangula (Ridge Gourd), Lagenaria siceraria (Bottle Gourd), Momordica charantia (Bitter Gourd), Solanum melongena (Eggplant) and Spinacia oleracea (Spinach) included various diseased leaves, fruits and onion bulbs were used for isolation of phytopathogenic bacteria and fungi. Many pathogenic bacteria species namely Erwinia species, Ralstonia species, Xanthomonas specis were identified on the basis of morphological, cultural characteristics and biochemical profile. Similarly fungal species of Alternaria, Aspergillus and Fusarium were also identified from diseased vegetables. These findings revealed that an average of 29.17% qualitative loss and 40.33% quantitative loss of vegetables occurs, which results a cumbrous loss in economy of Kohat
