My research focuses on isolating and identifying pathogens associated with avocado root rot. This project is under the supervision of Dr Noelani van den Berg and Prof Teresa Coutinho. The aim of this study is to investigate other causal agent of root rot in avocado and determine their potential effect on the host. The well known pathogen causing the disease is Phytophthora cinnamomi and has been studied extensively, although there are reports implicating other pathogens as causal agent of root rot. This study will also address synergistic effect between these pathogens.
