IRT-related research

Professor Pietersen’s research has covered wide ranging aspects of plant virology from viral diagnosis to epidemiology and control of agriculturally important crops. The main focus in recent years has been on grapevine leafroll disease of wine grapes, citrus tristeza virus, and citrus greening disease, associated with “Candidatus Liberibacter africanus”.
