The University of Pretoria conferred 20 postgraduate degrees – 13 PhD degrees and seven MSc degrees – to FABIans during the Spring graduation ceremony.
The 32nd Annual Symposium of the Tree Protection Co-operative Programme (TPCP) and DSI-NRF Centre of Excellence in Plant Health Biotechnology (CPHB) in FABI was hosted as a six-hour long hybrid meeting on 4 May.
On 20 January, FABI had the pleasure of hosting a virtual congress of the South African Society of Plant Pathologists’ (SASPP).
FABIans joined young researchers from several countries for the South African Society of Bioinformatics Student Council (SASBi-SC) Online Student Symposium from 4-6 August. FABIans contributed two oral presentations and a project overview to the 30 presentations at the online symposium.
FABI students and their co-authors contributed 37 posters/graphical abstracts of the 157 of these presentations at the MSA conference.
The situation the world’s population currently finds itself in with the global-spread of the COVID-19 virus – just one invisible pathogen - bears direct parallels to the research work that has been done in the TPCP over the past 31 years in combatting plantation tree pests and diseases.
The Australasian Plant Pathology Society (APPS) celebrated its 50th anniversary at their 22nd Biennial conference in Melbourne from 25-28 November. They met up with a number of FABIans at the meeting.
Eight Fabians attended the Fungal Genetics meeting in Asilomar, California during March 2019.
The 2019 meeting of the Southern African Society for Plant Pathology (SASPP) took place on the West Coast, hosted by Stellenbosch University.
