Evaluation of biorational pesticides against Leaf hopper, Empoasca kerri in groundnut ecosystem at different spraying intervals

Krishna Naik L, Somasekhar and Venkateshalu

The present study was undertaken with application of bio-rational like Agniasthra, Brahmasatra, Punchapatta, plant extracts, bio-pesticides, botanicals and indigenous technologies to overcome population of leafhopper, Empoasca kerri in groundnut ecosystem at Main Agricultural Research Station, University of Agricultural Sciences, Raichur during 2010-11 by using RBD design. Leaf hoppers population per two sweeps of hand ranged from 1.87 to 10.00 in Profenophos 50 EC and untreated control respectively. The standard chemical check profenophos 50 EC was found to be most effective and superior over all the treatments evaluated. Among different biorationals evaluated, the Neem Seed Kernal Extract (NSKE) at 5 per cent was found to be more effective in reducing the leaf hoppers population by recording less numbers of leaf hoppers (4.67/two sweep net) during 7th day after spraying.
