Abstract:

The field experiment on “Relative efficacy and economics of bio-pesticides” was conducted during 2012-13 and 2013-14 at Horticulture farm and Department of Entomology Rajasthan College of Agriculture, (MPUAT) Udaipur (Rajasthan) during rabi 2012-13 and 2013-14. The relative efficacy of three biopesticides viz.,Spinosad, Bt.k. and SlNPV in alone and in different combinations in nine different schedule (Spinosad-45SC at 200g/ha, Bt.k. (Dipel 8L) at 1lit, SlNPV-250LE at 250ml/ha, Spinosad-45SC at 200g/h-SlNPV-250LE at 250ml/ha SlNPV-250LE at 250ml/ha, Spinosad-45SC at 200g/ha-Bt.k.- (Dipel 8L) at 1lit -Bt.k-(Dipel 8L) at 1lit., SlNPV-250LE at 250ml/ha- Spinosad-45SC at 200g/ha- Spinosad 45SC at 200g/ha, SlNPV-250LE at 250ml/ha Bt.k.- (Dipel 8L) at 1lit-Bt.k.. (Dipel 8L) at 1lit, Bt.k.- (Dipel 8L) at 1lit Spinosad-45SC at 200g/ha-Spinosad-45SC at 200g/ha, Bt.k.- (Dipel 8L) at 1lit-SlNPV-250LE at 250ml/ha-SlNPV-250LE at 250ml/ha) was evaluated against S. litura revealed that treatment schedule comprising three spray of spinosad 45 SC at 200g/ha at 15 days interval was found most effective in reducing larval population up to 80.33 and 80.88 per cent during 2012-13 and 2013-14, respectively. It also recorded that higher head yield of 287.35 and 291.15 q ha-1 during rabi 2012-13 and 2013-14, respectively. The treatment schedule comprising three spray of Bt.k. (Dipel 8L) at 1 lit/ha at 15 days interval was found least effective which caused the minimum reduction of larval population with the mean of 56.09 and 55.24 per cent during rabi 2012-13 and 2013-14, respectively. The highest benefit: cost ratio of 1.419 and 1.407 was recorded in treatment schedule T1 copmprising three spray of spinosad 45SC at 200g/ha at 15 days interval during rabi 2012-13 and 2013-14, respectively.
