The field experiment to evaluate suitable and ecofriendly IPM modules was conducted at Turgarh village of Jhadol block of Udaipur district during Rabi 2018-19 and 2019-20 using 10 different modules. Results revealed that mean larval population of gram pod borer, Helicoverpa armigera was considerably low after evaluating sprays in different modules. The lowest larval population of insect (2.98 larvae /MRL) was recorded in Module 7, consissing of spinosad 2.5 SC @ 0.5 ml/l of water as 1st spray and indoxacarb 14.5% SC @ 1 ml/l of water as 2nd spray followed by module 1, consisting of clorfluazuron 5.4% EC @ 3 ml/l of water as 1st spray and indoxacarb 14.5% SC @ 1 ml/l of water as 2nd spray and module 2 consisting of spinosad 2.5 SC @ 0.5 ml/l of water as 1st spray and profenofos 50 EC @ 1.5 ml/l of water as 2nd spray in Rabi 2018-19 as well as in Rabi 19-20. Based on the benefit cost ratio module 6 Consisting of indoxacarb 14.5% SC @ 1 ml/l of water as 1st spray and profenofos 50 EC @ 1.5 ml/l of water as 2nd spray gave maximum return i.e. 1:2.04 & 1:2.12 respectively during first and second year, which proved more viable due to lower cultivation cost in both the seasons than all other modules evaluated during Rabi 2018-19 and Rabi 2019-20.
