Since the original description of the bacterium in the 1940s, the status of cashew (Anacardium occidentale, Anacardiaceae) as a host species has been unclear. mangiferaeindicae is the causal agent of bacterial canker of mango (Mangifera indica, Anacardiaceae), a disease of international importance. Although yellow pigmented isolates were found less aggressive as compared to creamy white ones. On the basis of these tests bacteria were found as X. Biochemical tests showed that all bacterial isolates were gram negative, salt tolerant, oxidase negative and showed negative growth while grown on asparagines medium. Mucoid colony growth was found when inoculated on nutrient agar with 5% glucose. Eighteen isolates were grown on asparagine and nutrient agar with 5% glucose medium to check their variability which depicted round, convex, creamy white and yellow pigmented colonies with entire margins. None of the cultivar was resistant against the disease although Anwar Ratool and Late Chounsa were least affected. Bacterial isolates were inoculated on different mango cultivars to evaluate the level of resistance. Thirty symptomatic samples were collected from multiple locations and associated pathogens were isolated. Maximum disease incidence was observed in Multan followed by Muzaffar Garh and Khanewal while minimum disease incidence was noted in Jhang and Lodhran district of the Punjab. A survey was conducted for bacterial black spot disease in different districts of Punjab.
