Pomegranate under threat: An overview of major diseases, their causal agents, and integrated management
Authors

Abstract
Pomegranate (Punica granatum L.) is affected by several diseases
caused by fungal and bacterial pathogens, resulting in significant losses in
yield and fruit quality, ultimately reducing its market value. Common fungal
pathogens include Botrytis cinerea (gray mold), Alternaria alternata
(heart rot), Aspergillus niger, and Coniella granati. Bacterial
diseases, particularly those caused by Xanthomonas axonopodis pv. punicae
(bacterial blight), also pose major challenges. Additionally, Neofusicoccum
parvum and Lasiodiplodia theobromae are associated with stem canker
and shoot blight, further threatening pomegranate production. Cell
wall-degrading enzymes (CWDEs) play a critical role in the pathogenesis of
fungal and bacterial infections in pomegranate, particularly during fruiting.
Key CWDEs involved include pectinases (such as polygalacturonase, pectin lyase,
and pectate lyase), cellulases, and hemicellulases. This review provides a
comprehensive overview of the pathogenic microorganisms and cell wall degrading
enzymes which affect pomegranate and examines current trends favouring
environmentally friendly and cost-efficient disease management practices over
chemical interventions.
