Abstract:
The present investigation was undertaken to find out suitable and low cost substitute for the management of Helicoverpa armigera (Hubner) on chickpea by using microbials and botanicals. The field trial was laid out in the premises of Insectary, Entomology Section, College of Agriculture, Nagpur, during the rabi season of 2013-14. The experiment was laid out in randomized block design (RBD) with three replications and eight treatments including control (water spray). The observations were recorded on average per cent reduction in the larval population, average per cent pod damage caused by Helicoverpa armigera (Hubner) and average grain yield of chickpea. Population of natural enemies were also recorded after application of treatments. The incremental cost benefit ratio (ICBR) was calculated on the basis of prevailing cost of inputs and grain yield. The highest incremental cost benefit ratio (ICBR) of 39.74 was registered in the treatment with quinolphos 25 EC 0.05 %, followed by Beauveria Basciana 108 conidia/ml 2ml/l (22.29)-2nd rank. The treatment spinosad 45 SC 0.01 % although recorded highest larval reduction (76.17 %) and maximum yield (15.23 q/ha), which stands 5th rank registering ICBR i.e. 15.85.
