Abstract

Identification of Pseudomonas fuscovaginae as the causal agent of bacterial sheath brown rot of rice in the North of Iran.

Abstract

A bacterial disease was observed on rice cv. Neda in Mazandaran, Iran, with symptoms including spikelet sterility, panicle discoloration and sheath rot of flag leaves. An aerobic Gram-negative, motile, rod-shaped bacteria was isolated from sheaths and panicles. Serological and pathological tests (using tobacco, wheat, rice and potatoes), and phenotypic characters confirmed the identity of Pseudomonas fuscovaginae as the causal agent. This is the first report of bacterial sheath rot of rice in Iran.
