A new bacterial disease of Russell prairie gentian (Eustoma grandiflorum) was found in Fukuoka Prefecture, Japan, in 1997. This disease was characterized by wilting and yellowing of the foliage. A cross section of the stem of a diseased plant revealed a tan to yellow-brown discoloration of the vascular tissue. A nonfluorescent, aerobic, Gram-negative bacterium was consistently isolated from infected plants. The bacteriological characteristics of 10 isolates of the bacterium coincided with those of the reference strains of Burkholderia caryophylli that were isolated from carnations. The bacterium, as well as the reference strains, attacked Russell prairie gentian and carnation after artificial inoculation and reproduced the symptoms similar to those after natural infections. On the basis of bacteriological characteristics and pathogenicities, the bacterium was identified as B. caryophylli. This is the first report of a disease caused by B. caryophylli on Russell prairie gentian; therefore, bacterial wilt of Russell prairie gentian is proposed as the name of the disease.
