PLG 351: General Plant Pathology

Research Interests:

  • Mushroom health and safety
  • Fresh Produce Food Safety
  • Biological control of citrus and tropical fruit diseases
  • Postharvest fruit pathology
  • Market access, Risk Assessment and Phytosanitary aspects in trade
  • An investigation into the link between water quality and microbiological safety of fruit and vegetables from the farming to the processing stages of production and marketing
  • Impact of climate change and globalisation on safety of fresh produce – governing a supply chain of uncompromised food sovereignty

Prof Korsten is currently responsible for the food safety and regulatory control programmes within the DST Centre of Excellence Food Security.  She is also responsible for the food safety programme within the Institute for Food Nutrition and Well-Being.  She is a chief editor of Crop protection and is chairing the International Society for Plant Pathology Task Force on Global Food Security.

Prof Korsten developed South Africa's first biocontrol agent for fruit and established a biocontrol research group at the University of Pretoria that has published extensively.  Prof Korsten has also established a fruit health group that focuses on food safety of fresh produce and on Sanitary and Phytosanitary aspects related to international trade.   

Prof Korsten has focussed her research mainly on complementary fields of postharvest technology and food safety as related to international trade in fresh produce requirements.  She has been able to establish research teams in food safety, postharvest technology, biocontrol and mushroom and fruit health. As a team they have been able to develop several innovative technologies to reduce disease and prevent product contamination. The value of her research programmes can best be illustrated by the strong industry financial support.  She has been able to attract extensive funding over her entire academic career and the high number of papers she has presented or published reflects the impact of her research work.  

Prof Korsten has had two projects funded by the Water Research Commission, titled “Evaluation of the risks associated with the use of rain water harvested from roof-tops for domestic use and homestead food gardens, and groundwater for domestic use and livestock watering”, and “An investigation into the link between water quality and microbiological safety of fruit and vegetables from the farming to the processing stages of production and marketing”.

Commercialisation of research outputs:

Prof Korsten has also developed one of the first biocontrol products in South Africa that was patented, registered and commercialised and that is still used in the South African fruit industry.  A similar citrus fruit disease biocontrol agent has recently been developed and is now in the process of being registered for commercial use.  Three new innovation technology applications are also currently being prepared for the UP research office.  One deals with a special packaging technology and one with biofilm development for litchi fruit and strawberries to control fruit disease.  One alternative mushroom casing material has also been developed from waste products and a technology to produce mushrooms in containers.
