Description Five strains of Streptomyces (AC-5, AC-6, AC-10, AC-18 and AC-19) and another five strains of Bacillus (BS-10, BS-15, BS-17, BS-
19 and BS-20) were earlier reported by us as biological control agents against Fusarium wilt of chickpea, caused by
Fusariumoxysporum f. sp. ciceri (FOC), and plant growth-promoting agents in chickpea. In the present study, the selected strains
of Streptomyces and Bacillus were further characterized for their antagonistic potential against dry root rot of chickpea, caused
by Rhizoctoniabataticola, by dual culture assay, blotter paper assay and in greenhouse. Both the Streptomyces and Bacillus
strains inhibited three strains of R. bataticola(RB6, RB24 and RB115) in both dual culture and blotter paper assays. When these
were further evaluated for their antagonistic potential against R. bataticolaunder greenhouse conditions, reduced incidence of
dry root rot was observed in Streptomyces and Bacillus treatments compared to the pathogen control.Among the ten strains
studied,AC-18and BS-20recorded the highest reduction of disease both at 30 days after sowing (DAS) (58% and 75%,
respectively)and 45 DAS (36% and 48%, respectively), when compared to the pathogen control.This study indicates that the
selected Streptomyces and Bacillus strains have the potential for biocontrol of dry root rot of chickpea.
