Soil Treatment with Nomuraea rileyi: A Promising Technique for the Control of Spodoptera litura on Groundnut

Soil treatment with Nomuraea rileyi conidia; together with its substrate, crushed sorghum, resulted in high mortality of Spodoptera litura larvae due to mycosis. The persistence of N. rileyi conidia, similarly applied to the soil in a groundnut field, was high, even at 2 weeks after application.
