Abstract/Contents: | "A distinctive leaf spot disease was observed on johnsongrass in NC. Lesions on mature leaves are ovate to oblong, up to 2x10 mm, with straw-colored centers and coffee-colored margins. A Bipolaris sp. isolated from lesions sporulated abundantly on sugar-proline agar, but poorly on V-8 juice agar or PDA. Johnsongrass seedlings inoculated with conidia developed lesions characteristic of the disease. Conidiophores on leaves are up to 280 um long with 3-5 pseudopleurogenous conidia. Conidia are fusoid, slightly curved, 8- to 9-septate and average 84(43-148) um long by 15(12-18) um diameter; the hilum is not conspicuous. Although morphologically similar to B. maydis, this species was not compatible with it in mating tests. Cultural characteristics and disease symptoms on johnsongrass are distinct from those of B. sorgicola and this species does not produce secondary conidiophores and conidia. Research is in progress to establish the identity and significance of this fungus for biocontrol of johnsongrass." |
