半夏主要病害研究进展OA

Based on literature reviews and production practices,the research progress on the classifications,pathogen spe-cies,epidemiological symptom,and integrated control technology of major diseases in Pinellia ternata was systematically reviewed to provide a scientific basis for disease prevention and control.At present,the major diseases identified in P.ternata primarily include corm rot(fungal dry rot and bacterial soft rot),stem-base diseases(damping-off,southern blight,and yellow damping-off disease),foli-ar diseases(leaf spot,leaf blight,and phytophthora blight),and viral diseases.The pathogen composition is highly complex,frequently manifesting as co-infections,and disease incidence is significantly influenced by climatic conditions and cultivation practices,and other factors.For disease management,agricultural measures such as crop rotation,the selection of healthy seed corms,and optimized field management serve as the fundamental basis.Biological control agents(e.g.,Paenibacillus polymyxa,Bacillus subtilis,and Tricho-derma spp.)are recommended,supplemented by the rational application of chemical pesticides for precise control.However,current research remains insufficient regarding the mechanisms of pathogen co-infections and regional variations in pathogen populations.Fu-ture studies should prioritize precise pathogen identification and monitoring,the integrated innovation of green control technologies,and the breeding of disease-resistant cultivars,and promotion of standardized cultivation,so as to facilitate the high-quality and sus-tainable development of the the P.ternata industry.
