Abstract

Somefactors were evaluated for controlling the root rot of Paspalum vaginatum. Fungi belonging to 10 genera were isolated from diseased plants. The survey showed differences in the frequency of the isolated fungi. In general, Fusarium semitectum, Helminthosporium tetramera, Macrophomina phaseolina, Pythium splendens and Rhizoctonia solani were found to be the most frequently isolated fungi. Percentages of post-emergence damping-off caused by the tested fungi were decreased in response to the effect of all tested treatments, i.e., biofertilizers, resistance inducers (chitosan and salicylic acid), biological control and chemical control, compared with check treatment.
