| Abstract | ||||
| Six biocontrol agents namely Trichoderma harzianum, T. Koningii, T.viride, two isolates of Bacillus subtilis and one isolate of Erwinia herbicola were tested for their antagonistic action against five pathogenic fungi causing lupin and chickpea damping-off,.i.e. Macrophomina phaseolina, Fusarium solani, Rhizoctonia solani and two isolates of F. semitectum. For measuring the bioagent activity the fungicide vitavax captan was used as standard. T. Koningii, T. harzianum and B. Subtilis isolate no (1) caused the highest reduction in linear growth of all the tested pathogenic fungi. All tested bioagents significantly decreased damping-off disease caused by M. phaseolina and F. solani in lupin seedlings and two isolates of F. semitectum in chickpea seedlings. The tested bioagents gave variable results against R. solani in lupin and chickpea seedlings. | ||||
