Occurrence of bacterial seedling rot in nursery flat, caused by grain rot bacterium Pseudomonas glumae

Abstract

A new type of seedling rot of rice was first discovered in Fukushima and Okayama Prefecture in 1974 and 1975. It occurred on young seedling in nursery flat prepared for rice transplanter. The disease was caused by the bacterium identified as Pseudomonas glumae, the rice grain rot bacterium. According to several experiments, it was assumed that the disease was caused by seed-borne and/or soil-borne pathogens.
