Occurrence of Garlic Rust in Southern Regions of Korea

Abstract

Occurrence of rust on 2 representative garlic cultivars Daeseo and Namdo in major cultivating regions of Goheung-gun, Jeonnam and Namhae-gun, Gyeongnam was investigated during 1998-1999. Rust disease severities of garlic ranging from 1.2 to 85.8 were quite different according to the investigating years and cultivars. Relatively high rust severities of garlic were observed in 1998 compared with 1999. This might be due to remarkably frequent rainfalls and high humidities during the growing seasons of garlic in 1998. Rust occurred severely on cultivar Daeseo but not on cultivar Namdo. This shows quite different susceptibility or resistance to rust among the cultivars of garlic. Increase of rust severities resulted in remarkable decrease in yields of garlic. It is assumed that rust might cause serious damages in the cultivation of garlic.
