Abstract

Rice straw stacks as a source of infection with the black kernel disease.

Abstract

Cultures made from dust blown from rice straw stacks, used as forage for cattle in Texas, during the spring and summer of 1939 showed the presence of several species of fungi, colonies of Curvularia lunata[Cochliobolus lunatus] being more numerous in those cases where the previous crop had been infected with black kernel disease, tentatively attributed to this fungus [R.A.M., xviii, p. 545]. It would thus appear probable that C. lunata is capable of overwintering in the straw stacks and new infection may result from spores blown to the flowering plants in the next season. Dry weather and high winds during the flowering period may increase the amount of infection.
