Assessments Of Sclerotium Rolfsii Potential Biocontrol By The Environment Friendly Trichoderma Species
Keywords:Trichoderma, Bioagents, Soil, Isolates, Sclerotium Rolfsii, Antagonistic.
A number of soil-borne plant pathogenic fungus have been effectively bio controlled by the bioagents Trichoderma species, which are known to be antagonists of other fungi. Irrigated field soil samples were used to isolate 47 local Trichoderma isolates utilizing diluted plate methods on Trichoderma selective medium (TSM). Bioassays and dual cultures on bean plants were used to explore the antagonistic capability of the local isolates against the phytopathogenic Sclerotium rolfsii. The disease index of bean plants was lowered by 67% when testing isolates were applied as a conidial solution. The rates of reduction varied, but they were all significant. According to the findings, differences in mycelium-coiling rate, sporulation, fungitoxic metabolites, induced growth response, and temperature impact explain why antagonistic potential varies between isolates. The potential biocontrol of eco-friendly Trichoderma species by Sclerotium rolfsii is examined in this paper.
