Abstract

For selection of effective antagonists for control Sclerotinia rot of lettuce, 29 bacteria were isolated from soil in Korea. The bacterial isolates M27 and RM43 identified as Bacillus sp, were selected as prospective agents for inhibiting mycelial growth of Sclerotinia sclerotiorum and Sclerotinia minor. Among the selected isolates, Bacillus amyloliquefaciens M27 effectively suppressed incidence of Sclerotinia rot by Sclerotinia sclerotiorum and Sclerotinia minor in the lettuce nursery.
