Bacterial sheath rot of rice in Russia
EPPO RS 508/06 of 1990-11 referred to the discovery that bacterial sheath rot of rice is present in many more countries than originally reported. Matveieva et al. report that, in Primor'e territory in the Far East of Russia, bacterial sheath rot is caused by two bacteria: Pseudomonas fuscovaginae (known from Japan, Latin America and Africa) and P. syringae pv. syringae (cosmopolitan, but reported from rice in Europe, Australia and Chile). The disease is often epiphytotic. Brown spots appear on the leaves and sheaths at the time of maximum tillering. The plants stop growing, the inflorescences emerge poorly, seeds are shrivelled and grain yield is reduced.
