There was a greater accumulation of
almost all phenolic acids in tomato leaves treated with actinomycetes
and further challenged with R. solani than those treated with
biocontrol agents only and the control (Table 1). Inoculation with R.
solani produced the typical disease symptoms and resulted in final
plant death. All bioagents used in this study reduced disease
symptoms as well as mortality at different levels (23e41%) with
maximum reduction in the treatment with vh6 as compared to
control. Isolates vh8 and vh85 also showed considerable reduction
of disease severity
