ABSTRACT

Thirteen isolates of Gliocladium spp and four isolates of Aspergillus niger obtained from
different sources viz., soil, rice rhizosphere, rice leaves and rice leaf sheath were evaluated for
their biocontrol ability against R. solani, the causal agent of sheath blight of rice. Four isolates
of Gliocladium spp.(1, 24, 29 and 30) and 4 isolates of Aspergillus niger (35, 36, 37 and 38)
were found effective in dual culture. Hyphal interactions between biological control agents and
R. solani were observed as hyperparasitic coiling, penetration and finally resulting lysis and
collapse of R. solani. Two isolates of Gliocladium spp. (1, 33) and all four isolates of A. niger
were found highly inhibitory to the mycelial growth of the pathogen by producing volatile
substances. Culture filtrate of the promising isolates of antagonists were also inhibited the
growth of the pathogen.
