Integrated Disease Management in Forest Nurseries and Plantations in the Tropics

Forest nurseries and tropical forest plantations face various disease threats that can reduce seedling quality, inhibit tree growth, damage woody tissues, and cause significant economic and ecological losses. Disease development is influenced by complex interactions among pathogens, host susceptibility, and environmental conditions, including site characteristics, microclimate, and silvicultural practices. Effective disease management therefore requires an integrated approach that considers not only the symptoms and characteristics of individual pathogens but also the factors contributing to disease establishment, transmission, and spread. Integrated Disease Management (IDM) combines preventive, cultural, biological, mechanical, and chemical strategies to reduce disease incidence and severity while maintaining environmental sustainability. Understanding and applying these principles is essential for forest managers, researchers, and practitioners in developing practical and environmentally responsible solutions to protect the health and productivity of tropical forest plantations.

Integrated Disease Management in Forest Nurseries and Plantations in the Tropics is an intermediate-level course designed to introduce the concepts, principles, and practical applications of integrated approaches to managing forest plant diseases. The course explores the interactions among pathogens, host plants, and environmental factors, as well as the influence of site conditions, microclimate, and silvicultural practices on disease development. Through six learning topics, participants will examine the symptoms, disease development, transmission pathways, and management strategies for major forest plant diseases, including gall rust, myrtle rust, Ceratocystis disease, Ganoderma diseases, bacterial leaf blight, and pink disease. Learning activities are designed to strengthen participants’ ability to assess disease conditions, analyze disease cases, and develop effective, practical, and environmentally friendly management strategies for tropical forest nurseries and plantations. Upon completion, participants are expected to apply integrated disease management principles to support sustainable forest health and plantation productivity.
