My current role is a Postdoctoral Fellow at FABI within the University of Pretoria. The focus of my research is the taxonomy of novel species of Lasiodiplodia from tree hosts collected from warm temperate Zambia. Lasiodiplodia is a fungal genus within the order Botryosphaeriales. This order contains many important plant pathogens, endophytes and saprobes, such as Diplodia sapinea, a common pine pathogen, Dothiorella pretoriensis, a dieback pathogen of Acacia karroo, and Lasiodiplodia theobromae, a pathogen of Theobroma cacao (cocoa). Myrtales is an economically important order of plants which includes Eucalyptus and Syzygium.

 

To date my work has uncovered seven new species of Lasiodiplodia which may be pathogenic to forestry and native plant species. Further pathogenicity testing will confirm the virulence of the fungi and the susceptibility of host trees. The outcomes of this research will provide South African and global forestry with valuable knowledge of new and emerging disease threats, whilst also informing biosecurity, quarantine and other government and non-government stakeholders.
