Studies on the susceptibility of Akiochi (autumn-decline) rice plant to Helminthosporium blight

(1) Essential vitamines, minor elements and suitable synthetic media of Cochliobolus miyabeanus

Abstract

Cochliobolus miyabeanus, the causal fungus of Helminthosporium blight of rice plant, is not grown in Richard's synthetic medium prepared with the purified minerals, and addition of Biotin, Thiamin, Fe, Mn and Zn to the medium are necessary for the growth of this fungus. From this fact, the constituent of the synthetic medium for this fungus is shown in Table 5.
