Antagonistic activity
Actinomycetes strains were primary screened in vitro (labcondition) by dual-culture assay to evaluate their antago- nistic effect against four important crop (Tomato, Soya- bean, Chilli and Rice) damaging plant pathogenic fungi, that is, F. oxysporum, C. tranctum, H. oryzae and C. capsici respectively. A single potent actinomycete strain CPP-53 is found to have antagonistic effect over all four pathogens. The observation was recorded on 3 rd and 5 th day after dual culture inoculation, S. flavofuscus CPP-53 showed maximum (61.53%) inhibition over H. oryzae followed by F. oxysporum (57.05%), C. tranctum (54.05%) and C. capsici (50%), and restricts growth of aerial mycelium (Figure 1)
