Investigation was carried out on field evaluation of formulations of Nomuraea rileyi (Farlow) Samson and spray equipments against Helicoverpa armigera (Hubner) in chickpea. Among different formulations of N. rileyi and spray equipments, oil based (tank mix) formulation sprayed with high volume sprayer (42.96%) was found significantly superior in causing higher mycosis. However, high volume sprayer with RPP recorded significantly lowest per cent pod damage (22.83%) and significantly higher yield (11.31 q/ha) followed by high volume sprayer with oil based formulation (9.97 q/ha). High volume sprayer with RPP was also the most profitable with the highest net returns of Rs. 14,096 and B:C ratio of 3.5 followed by high volume sprayer with oil based formulation (net returns of Rs. 11,952 and B:C ratio of 2.9). High volume application of N. rileyi could be incorporated ss one of the components of managing H. armigera in chickpea.
