| Abstract: | Lots of isolates were obtained by isolation. But according to the results of the pathogencity test and indetification, Pathogenetic bacteria have 6 isolates, including 5 Erwinia spp. and a pseudomonas sp., Pathogenetic fungi includes 3 Fusarium spp., a Alternaria sp. and a Diplodia sp., Among these pathogens, Erwinia spp. and Fusarium spp. were the most frequently isolated species making up 45.5% and 27.3% respectively, and it was reported for the first time in China that Erwinia spp. infected rice grains. |
