Efficacy of biopesticides against leaf miner in tomato (Solanum lycopersicum L) var Solan Lalima under mid-hill conditions of Himachal Pradesh

The present study was conducted at the Department of Seed Science and Technology of Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh to examine the effect of various biopesticides on leaf miner population in Solan Lalima variety of tomato (Solanum lycopersicum L) under the mid-hills of Himachal Pradesh during 2018-2019. Different combinations of biopesticides were employed in the study, including Trichoderma viride, neem cake, neem oil, cow urine, Bacillus thuringiensis and HaNPV, each used at different concentrations. The results of the study indicated that yield per ha, gross income per ha, net return per ha and BC ratio were highest in the treatment comprising T viride 50 g + FYM 10 kg/plot + neem oil 5 ml/l (53,657.00 kg, Rs 1,073,140.00, Rs 710,790.00 and 1.96 respectively). Therefore, this treatment could be recommended for control of leaf miner in tomato var Solan Lalima in mid-hills of Himachal Pradesh.
