Abstract:

The experiment was conducted to study of biology of H. armigera in relation to abiotic factors (temperature, relative humidity, rainfall etc.), to evaluate the efficacy of some botanicals and organic compounds against H. armigeraand workout the economics of different treatments with Incremental Cost Benefit Ratio (ICBR), H. armigera on field pea in Rabi 2018-19. Result showed that the population of H.armigera appeared on 4th week of November (1.15 larvae/ 5plant) i.e. 47th Standard Meteorological Week (SMW) & reach its peak (15.10 larvae/ 5plant) during 52nd SMW i.e. last week of December. The pest population gradually decreased (0.8 larvae/ 5plant) in the 3rd week of February i.e. 7th SMW due to the reason of crop maturity. Regarding efficacy of treatments cow urine + neem leaf proved most effective which was closely followed by cow urine + tobacco leaf and cow urine + lantana leaf. Maximum yield i.e. 21. 40q/ha was given by cow urine + neem leaf which was closely followed by cow urine + tobacco leaf and cow urine + lantana leaf. ICBR of cow urine i.e.1:15.5 was the highest followed by cow urine +neem leaf having ICBR 1:13.52. Similar trend in percent increased yield over control was observed in this investigation.
