|a Pseudophaeomoniella globosa has recently been identified as a pathogen contributing to olive trunk diseases in South Africa. Little is known regarding the biology and epidemiology of this pathogen. The aim of this study was to investigate whether olive pruning debris act as an inoculum source of P. globosa in established orchards. A nested species-specific PCR was developed for the detection of this pathogen on 138 samples of pruning debris collected from Paarl (40 wood pieces), Stellenbosch (42 wood pieces), and Worcester (56 pieces) in the Western Cape Province, South Africa. Spore washes were made from the samples (5 to 10 cm in length), after which the nested species-specific primers were used to determine the presence of P. globosa on the wood. P. globosa was detected on 37.5% of the pruning debris collected from Paarl, 61.9% from Stellenbosch, and 39.3% from Worcester. The pruning debris that tested positive for P. globosa were evaluated visually by microscopic observations for P. globosa pycnidia. Dark-brown to black pycnidia were found. Conidia from these pycnidia were measured, cultured, and confirmed as P. globosa by sequencing the internal transcribed spacer region. In this study, the pruning debris in established olive orchards were identified as inoculum sources of P. globosa. This study emphasizes the importance of additional means focused on reducing the inoculum sources of this pathogen in these orchards as an additional management strategy against olive trunk diseases
