Species of Botryosphaeria are commonly associated with canker and dieback symptoms in grapevines. Our research has also shown that several of these species are frequently encountered as latent pathogens or endophytes, and that disease ensues following the onset of stress. We have studied these organisms on eucalypts, and are in the process of characterising them on the Proteaceae, fruit trees, and also grapevines. Major questions that we are addressing concerns the phylogeny of Botryosphaeria, which appears to represent several genera, as well as the recognition of usable morphological features for their identification, and molecular kits for early detection. Several species are also being epitipified, and a phylogeny to most species in the genus has already been generated, with the aim of compiling a monograph of the genus.
