Hello!

 

I am a MSc student in the Tree Protection Co-operative Programme (TPCP) at FABI.  My research project is on the important rust pathogen, Puccinia psidii, I will be  investigating the diversity of P. psidii populations in South Africa under the supervision of Prof. Jolanda Roux and Dr. Alistair McTaggart. This pathogen causes serious damage to plants in the Myrtaceae family (eucalypts, guava, clove and myrtle) and is of international importance. Quite a few species of Myrtaceae are native to South Africa and are being threatened by this pathogen in both gardens and natural forests. Furthermore, genotypes of Puccinia psidii in Australia and Brazil are causing serious damage to Eucalyptus trees in plantations. However, very little is known regarding the South African genotype. Thus, my study includes a national survey of native Myrtaceae in South Africa, screening of plantation Eucalyptus species and native Myrtaceae and working towards understanding the importance and predicting the future of this pathogen in South Africa.
