Online ahead of print.ABSTRACTAsia supports major food, horticultural, and plantation crops, yet uneven loss data and surveillance capacity hinder continental-scale prioritization of plant diseases. This review integrates FAOSTAT crop statistics, EPPO pathogen occurrence and host records, Scopus affiliation- based publication data, and disease-specific literature to identify regional surveillance and management priorities. Wheat, rice, maize, and potato accounted for nearly three quarters of the documented crop-pathogen intersections, highlighting shared staple-crop vulnerabilities. Rice blast, bacterial blight, sheath blight, and viral diseases remain major concerns in Eastern, Southern, and South-eastern Asia, where intensive cultivation and changing pathogen populations complicate durable control. Wheat rusts, bunts, and cyst nematodes warrant attention in Central, Southern, and Western Asia, while wheat blast highlights the introduction risks in Southern Asian. Fusarium head blight and maize ear rots link crop protection with food and feed safety. Potato late blight, viral degeneration, and bacterial wilt emphasize seed-tuber health in temperate and highland systems. In South-eastern Asia, cassava mosaic disease, banana Fusarium wilt, and oil palm basal stem rot present challenges associated with infected planting material and persistent inoculum. Tomato viruses threaten Western Asian protected horticulture, while citrus huanglongbing and fire blight highlight the need for healthy nursery stock and early detection. These regional disease profiles call for management tailored to production systems and pathogen biology, prioritizing durable resistance in cereals, healthy planting material in vegetatively propagated crops, and containment of persistent soilborne diseases. Standardized diagnostics, coordinated surveillance, and resource sharing can strengthen disease management across regions with unequal research and surveillance capacity.PMID:42901223 | DOI:10.5423/PPJ.RW.07.2026.0104
