Expertise

Molecular characterisation and detection of sugarcane pathogens and endophytes by PCR, RT-PCR and sequencing.

Management of quarantine glasshouse, advice on import and export of sugarcane varieties.

Plant micropropagation by meristem tissue culture for the elimination of sugarcane pathogens.

Research Interests

Molecular diagnosis and identification of sugarcane pathogens in the quarantine glasshouse and in the field.

The performance of imported cold tolerant varieties in frost areas.

The use of endophytic microorganisms in the control of sugarcane fungal diseases.

Soil microbial organisms and their role in soil health.

Key Outcomes

The development of mosaic and smut management strategies for the Mpumalanga region, Identification of fungicides for smut and brown rust management.
