초록

The Gyeongsangnam-do Agricultural Research and Extension Services (GARES) provides diagnoses of diseases and disorders causedby fungi, bacteria, viruses, and nematodes of commercial agricultural crops grown in Gyeongsangnam-do, South Korea. Between 2020and 2024, the GARES received 3,227 samples including field and greenhouse vegetable crops, fruit including berries and grapes, graincrops and potato, floriculture crops, and nuts for diagnosis. Vegetables accounted for 68% of all diagnoses, with most cases comingfrom greenhouse-grown vegetables such as peppers, strawberries, tomatoes, and paprika. Pathogen categories comprising most of thesamples included fungi and oomycete diseases (46%), the most frequently diagnosed each year, followed by viral diseases (25%), bacterialdiseases (18%), and nematode diseases (11%). Among fungal diseases, Fusarium wilt disease was the most common, accounting for35% of all fungi and oomycete diseases. The viral diseases diagnosed were mainly TSWV (142 samples), PepMoV (123), ToCV (100),and TYLCV (79). Among bacterial diseases, bacterial wilt disease accounted for more than half of the total, and was particularly prevalent in solanaceous vegetables such as peppers, eggplants, and tomatoes. Root-knot nematodes accounted for over 87% of all nematode diseasesamples. No fire blight was observed. Tomato chlorosis virus (ToCV) in paprika and hairy root disease associated with Rhizobium rhizogenesin greenhouse tomatoes were detected for the first time in the GARES, and are the first report in South Korea. This study systematicallyanalyzed disease diagnostic data from the Gyeongnam region and will likely serve as valuable baseline data for future disease forecasting,comprehensive pest management, and control policy development.
