Soybean is an important food legume in Thailand. Three recommended varieties, namely 'S.J.1', ' S.J.2 ' and 'S.J.4', are commonly used at present. These varieties are susceptible to rust, caused by Phakopsora pachyrhizi Syd. , which is one of the serious soybean diseases in Thailand , especially when soybeans are planted in the wet season.
