Bacterial diseases of rice
Two bacterial pathogens of rice appear on the EPPO Al List (Xanthomonas campestris pvs oryzae and oryzicola), and remain the most important globally. Pseudomonas fuscovaginae (bacterial sheath rot) has now also been shown to cause serious damage, while P. glumae (bacterial grain rot) has become important in Japan since the introduction of seedboxes for mechanical transplantation. (H. Kaku, Tropical Agriculture Research Center, Ibaraki 305; abstract Sp. I-1-3). Techniques for detection and diagnosis of P. glumae have been described (S. Mogi, Indonesia-Japan Joint Programme on Food Crop Protection, Jakarta, ID; abstract St. XIII-3-3).
P. fuscovaginae and P. glumae have both been found in Latin America (R. S. Zeigler and E. Alvarez; CIAT, Cali, CO; abstract St. XIII-1-16). P. fuscovaginae has been shown to be seed-transmitted (K. Miyajima, Agricultural Experiment Station, Kunneppu, Hokkaido 099-14; abstract St. XIII-1-27). Strains of X. c. oryzae characterized in USA have been found to be only of low virulence (RK. Jones et al., Texas A&M University, College Station, Texas 77843; abstract P. II-1-BT
