One of the significant kharif crop of India is maize. It is unmistakably a summertime annual that needs extremely specific environmental conditions for healthy growth and development. It is grown all over the world in the temperate, subtropical, and tropical regions. Sheath blight, caused by Rhizoctonia solani, causes corn grain losses ranging from 11 to 40%, even up to 100% on some cultivars in some warm, humid locations, where the circumstances are suitable for the causative agent (Izhar and Chakrabarty 2013; Gao et.al., 2014). To gradually destroy this causative agent, a number of compounds are utilised. However, this same bacterium has also developed resistance to systemic fungicides like benomyl, carboxin, and thiophenate methyl as well as protectant organic fungicides like captan, maneb, and thiram. To manage this diseases, biological treatment options were tested in the current experiment. A biocontrol agent, Trichoderma, was tested in vitro against the pathogen R. Solani using several species. As a consequence of its ability to 80% effectively block the growth of pathogens, T. harzianum emerged as the most promising of the ten Trichoderma strains studied in this study. The pathogen was also exposed to certain botanicals (essential oils), and Neem oil (Azadirechta oil) showed the most promising results in thwarting the growth of the infection, followed by clove oil and mentha oil.
