<![CDATA[Chili pepper (Capsicum spp.) is a high-value horticultural commodity whose production is frequently constrained by diseases caused by fungi, bacteria, viruses, and nematodes, which can substantially reduce yield when left unrecognized and unmanaged. Farmers' limited ability to identify disease types and understand the factors driving their development in the field remains a recurring obstacle in cayenne pepper cultivation. This activity aimed to strengthen the capacity of farmers at the Ngandong Jaya Farmer Group, Ngandong Village, Grabagan District, Tuban Regency, in recognizing major chili pepper diseases and understanding the disease triangle concept as a basis for designing control strategies. The activity was conducted on 25 January 2025 as part of the Farmer School program, beginning with routine observation of the demonstration plot and sampling of symptomatic plants for diagnosis, followed by group discussion and a dedicated presentation by Dr. Ir. Mintarto Martosudiro, M.S. of the Faculty of Agricultural and Forestry Bio-industry, Universitas Brawijaya. The material covered the three components of the disease triangle, namely host plant, pathogen, and environment, together with management strategies for each component as a foundation for applying Integrated Pest Management (IPM) principles. Ten major chili pepper diseases were also introduced, comprising anthracnose, Phytophthora blight, Fusarium wilt, bacterial wilt, Cercospora leaf spot, bacterial leaf spot, mosaic virus, yellow disease, root and collar rot, and root-knot nematode, together with their causal pathogens and main symptoms. Results indicated an improvement in farmers' understanding of chili pepper diseases and the disease triangle framework, which is expected to encourage more targeted and sustainable disease management practices at the Ngandong Jaya Farmer Group.]]>
