Abstract

In this study the interactive effect of a plant growth promoting fungus (PGPF) Penicillium sp. EU0013 was used as biocontrol agent using seed priming and soil drench method against Fusarium solani which is causal agent of root rot of Okra. Different conidial concentrations of EU0013 (1× 105, 1 ×106 and 1× 107 conidia mL-1) were prepared and applied under field condition by using the above mentioned methods. Under field condition data was recorded on disease severity (%) and seedling mortality (%),of fungal species in the okra rhizosphere. Results showed that Penicillium sp. EU0013 applied at 1×107 conidia mL-1 as seed priming significantly reduced disease severity 22.17% and seedling mortality by 13.8%, in okra rhizosphere. It can be concluded that root rot in okra caused by F. solani was efficiently controlled by the application of plant growth promoting fungus (PGPF) Penicillium sp. EU0013 as biocontrol agent using seed priming method as compared to soil drench method.
