The virulence of dry formulations of Nomuraea rileyi for different storage conditions was tested against third instar larvae of Spodoptera litura (Fab.). Talc formulations retained the virulence of N. rileyi for relatively longer period (45 per cent mortality after 3 months storage, 30 per cent after 4 months) than other formulations.

Abstract


The virulence of dry formulations of Nomuraea rileyi for different storage conditions was tested against third instar larvae of Spodoptera litura (Fab.). Talc formulations retained the virulence of N. rileyi for relatively longer period (45 per cent mortality after 3 months storage, 30 per cent after 4 months) than other formulations.
