Aims The efficacy of three isolates endophytic Penicillium species that have shown significant suppressive effect on root rotting fungi in our previous study were further evaluated pots and field plot experiments for their diseases okra, induction systemic resistance physiochemical properties okra fruit. Methods Results Aqueous suspensions Pseudomonas monteilii applied plots using as test plant. Data the fungal infection roots, plant growth, markers like polyphenol, salicylic acid antioxidant status determined. These significantly suppressed induced via increasing level markers, polyphenol besides improving activity P. monteilii-treated plants compared to control plants. GC-MS analysis n-hexane extract mycelium nigricans revealed presence 15 different volatile compounds. Conclusions Endophytic potential against root-infecting can improve growth yield. Significance Impact Study suppress by direct mechanism or
