Pathogenic Capacity of Helminthosporium spiciferum: Foliar Parasite of Rice in Morocco

In this study, artificially inoculation of six rice varieties widely cultured in the Gharb with Helminthosporium spiciferum showed different sensitivities against this isolate used. The foliar lesions are different from those noted on the plants of rice inoculated by Helminthosporium oryzae. Oryza sativa = rice/Helminthosporium spiciferum/ symptoms.
