Abstract:
The present study was conducted at Department of Entomology, Dr. PDKV, Akola to Evaluate the different Modules for management of Exelastis atomosa in Pigeon pea. In this investigation, four different modules and an untreated control were tested. The observations on the effect of different modules on larval population of Exelastis atomosa were found statistically significant. However, as regards to the influence of different modules against larval population of E. atomosa, the Chemical module-II (M2) recorded minimum population of E. atomosa i.e. 0.45 larvae per plant and was significantly superior over all other modules, followed by the Chemical module-I (M1) and IPM module (M4) with 0.98 and 1.13 larvae of E. atomosa per plant, and were statistically at par with each other. However, the Bio-control module (M3) recorded comparatively higher i.e. 1.43 E. atomosa larvae and was significantly superior over an untreated control which recorded highest population i.e. 2.13 larvae per plant. However, the highest grain yield of pigeon pea (2103 kg/ha) was obtained in the Chemical module-II (M2). The Chemical module-I (M1) and the Bio-control module (M3) registered yield levels of 1968 and 1780 Kg/ ha, respectively. The IPM module (M4) recorded lower yield of 1680 kg/ha as against 1543 Kg/ha in an untreated control. The highest ICBR of 1:4.00 was estimated in the Chemical module-II (M2) and was economically most viable module. It was followed by the Chemical module-I (M1) which recorded ICBR of 1:3.59, whereas, the Bio-control module (M3) and the IPM module (M4) recorded comparatively lower ICBR of 1:3.46 and 1:0.96, respectively.
