Abstract | Rhynchosporium alismatis is a potential mycoherbicide for suppression of Damasonium minus in rice fields. The effects of cultural and environmental conditions on sporulation, conidial germination, germ-tube elongation and conidial infectivity were investigated. R. alismatis sporulated on a range of solid media and those based on lima bean produced the largest numbers of viable and infective conidia. The fungus also sporulated abundantly in liquid media. Light had no significant effect on conidial production. Sporulation, germination and germ-tube elongation were greatest at 25°C and 30°C. Lesion development on leaf tissues of D. minus was enhanced at 25°C but reduced at temperatures ≥30°C. |
