FABI intern
My name is Mandlenkosi Dube, and I am currently a junior plant pathologist. In terms of my academic credentials, I proudly graduated with a BSc Honors in Plant Pathology from the University of KwaZulu-Natal (Pietermaritzburg) under the esteemed supervision of Dr. Z.R. Zwane. My honors project focused on evaluating the efficacy of Bacillusspecies in controlling a devastating disease affecting avocados, particularly the Hass cultivar. This disease, known as Anthracnose, is primarily caused by the fungal pathogen Colletotrichum gloeosporioides. This project provided me with invaluable insights into the real-world interactions of pathogens, transcending theoretical knowledge. The results compellingly indicated that Bacillus species possess antagonistic properties.
Professional Experience
Beyond my academic pursuits, I have undertaken various roles both during and after my studies. I initially worked at LEOMAT, an engineering company, and subsequently accepted a six-month position at Sunshine Seedling Services in Pietermaritzburg in pursuit of advancing my knowledge in agriculture mostly with a hands-on experience, which commenced in 2025 and concluded in February 2026. In this role, I contributed as a research assistant within the nursery department, focusing on both the vegetable section and the forestry department. My responsibilities involved the propagation of diverse forestry plants and optimizing seedling growth in elleports. Following this, I secured an 11-month internship at the Forestry Agricultural and Biotechnology Institute (FABI) at the University of Pretoria. With this opportunity, I aspire to further my studies, particularly pursuing an MSc and potentially a PhD, should divine providence allow.
Research Interests
My research interests predominantly revolve around preharvest plant pathology, with a strong emphasis on disease prevention and the promotion of plant health during cultivation. These interests also extend into postharvest management, as healthier crops typically demonstrate enhanced storage qualities and diminished disease-related losses. My specific research interests include:
- Phage-host interactions (phage biology) - Disease resistance and sustainable disease management, particularly through biological control methods for economically significant crops - Sustainable development, livelihood, and food security, aligned with the African Agenda 2063 - Soil microbiome diversity - Precision agriculture and smart farming - Plant disease epidemiology
Currently, I have formulated three research topics that align with my interests and capabilities. The first topic investigates the synergistic effects of soil-borne microbiome diversity and precision agriculture on potato yield and disease resistance. The second topic focuses on phage-host interactions, specifically exploring the potential for biocontrol of citrus canker disease in South Africa. The third topic examines the epidemiology of Clavibacter nebraskensis, the causative agent of Goss's wilt in South African maize. This research will particularly involve investigating the population structure (diversity and gene flow) and host range of C. nebraskensis isolates collected in South Africa. However, I remain open to exploring other research opportunities.
Skills and Competencies
In terms of skills, I possess a unique combination of competencies that I have cultivated throughout my extensive and fulfilling journey. I have developed critical skills such as active listening, trust-building, goal identification, and capability development. Additionally, I excel in inspiring others, managing risks, and fostering opportunities, all while demonstrating proficiency in critical thinking. In my previous roles, I have contributed to organizational improvements, as detailed in my curriculum vitae (available upon request), and have actively participated in collaborative team efforts to achieve key mentoring objectives.
