Abstract:
Field experiments were carried out to evaluate the avoidable yield losses caused by fall armyworm, Spodoptera frugiperda on maize during Kharif, 2019-20 and 2020-21. The results of pooled data of both the years revealed that the mean larval population (1.04 larvae/plant), leaf and cob damage rating (2.40 and 1.22, respectively) at V9 and R3 crop stage respectively, were significantly lowest in protected plots over the unprotected plots (3.64 larvae/plant, 5.68 and 3.54, respectively). Highest grain yield was recorded in protected plots in comparison to the unprotected plots (50.62 and 33.93 q/ha, respectively) with an overall reduction of 32.93 %.
