Diseases of Passion Flower ( Passiflora spp . )

There may be many factors contributing to reduction in longevity and productivity in passion fruit plants, especially diseases of viral, bacterial or fungal etiologies, among which passion fruit woodiness, bacterial spot, root and collar rot, fusarium wilt, anthracnose and scab are the most important. The incidence of woody fruits in young plants totally compromises the productivity and quality of fruits. Fusariosis, root and collar rot have swept out entire crops, leading to irreversible wilt and consequent death of plants. Bacteriosis, anthracnose and scab cause severe losses under favorable environmental conditions and the absence of preventive control. The permanent incidence of diseases in some areas may turn the crop unprofitable, causing its periodical migration to new areas. This review will cover the main passion fruit diseases, their symptoms, etiology, epidemiology and management. _____________________________________________________________________________________________________________
