Cross pathogenicity of Botryodiplodia theobromae, an original isolate from guava fruits on the different cultivars of mango

The objectives of this study was to determine the cross pathogenicity of Botryodiplodia theobromae, an etiological agent of post-harvest stem end rot, on the fruits of different cultivars of mango. In the present investigation, the pathogen B. theobromae was able to cause virulence in the different cultivar of mango namely safeda, kesar and dasheri during the post-harvest storage stage. Disease ability of pathogen was measured in the loss in physiological weight (PLW %), diameter of disease lesions and disease incidence (%) under both controlled and ambient conditions. Different cultivar of mango showed susceptibility to the attack of pathogen, when inoculated via plug inoculation. In the background of huge post-harvest wastage by fungi, this is unique kind of study revealing how stem end rot pathogen is responsible for inducing spoilage in the several mango cultivars. These finding can be good platform for applying correct type of control strategy for minimizing spoilage caused in mango and other fruits due to rot causing fungal pathogens.
