Abstract:   (5235 Views)
Aeluropus littoralis belong to poaceae family. It often grows in salty soils. In this study reaction of A. littoralis to rice pathogens (Pyricularia grisea, Rhizoctonia solani and Bipolaris oryzae) was investigated at greenhouse and field conditions under artificial inoculation. These three mentioned fungi were isolated from rice plants and then propagated and separately inoculated on Aeluropus plants. The results indicated that R. solani and P. grisea could infect the A. littoralis and showed the typical symptoms on this plants. This is the first report of these fungi that infect the A. littoralis plant in northern Iran. But B. oryzae could not infect the A. littoralis, and was not showed brown spot symptoms on plants at greenhouse and field conditions. Aeluropus can be an alternative host for the blast and sheath blight of the rice. Therefore, eradication of this weed can reduce the inoculum sources of the two important rice pathogens. Also it can be source of resistance to rice brown spot disease. Beside, the possibility of existence of other tentative methods for considering this disease must be studied and researched in the future.
