Antagonistic activity
Actinomycetes strains were primary screened in vitro (lab
condition) 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).
