Research and services on all post-harvest diseases, and most
specifically on green and blue mould, sour rot, Phytophthora
brown rot, anthracnose and stem-end-rots, and focuses on the
aspects summarised below:
Market
Access
1. Adherence to permitted MRL levels
2. Packaging of local and international research findings
to facilitate market access negotiations
3. Microbial food safety
Etiology + Diagnosis
1. Develop detection techniques to facilitate rapid
detection and diagnosis
2. Characterise variability in pathogen populations
Epidemiology
1. Study epidemiological aspects that would facilitate
improvement of management strategies
Disease management
1. Formulation and evaluation of management strategies
during pre-harvest and post-harvest stages
2. Structuring of pre-harvest spray programmes to
reduce inoculum loads on harvested fruit
3. Implementation of strategies to limit fungicide
resistance buildup
4. Evaluation of novel and GRAS chemical compounds
and biocontrol agents for postharvest disease
control
5. Integration of cold chain management strategies with
regard to fruit quality, rind condition, pre-
and post-
harvest decay management
Inoculum Management
1. Formulation and evaluation of pre- and post-harvest
sanitation strategies that would reduce contamination
of harvested fruit.
