Plant Pathology

Plant Pathology is a core specialization within the discipline of Crop and Plant Sciences, itself part of the broader academic field of Agriculture & Forestry. It examines the biology, ecology, and management of plant diseases caused by fungi, bacteria, viruses, nematodes, oomycetes and abiotic stresses, combining laboratory diagnostics, field epidemiology, and systems-level control strategies. Students in Plant Pathology programs learn pathogen identification, disease surveillance and modelling, integrated disease management (including cultural, biological and chemical controls), host-pathogen interactions, and principles of biosecurity and quarantine to protect crop health and food systems.

With mounting pressure from population growth, global trade, and a changing climate, plant disease threats are evolving in scale and complexity. Plant Pathology plays a pivotal role in safeguarding yields and quality by integrating classical plant-microbe science with modern tools, genomics and molecular diagnostics, remote sensing and decision-support modelling, and digital surveillance, to detect emergent pathogens, forecast outbreaks, and design durable management strategies.
