Abstract

Field experiments were conducted during kharif 2017–2018 at Aruppukottai and Narikudi blocks, Virudhunagar district, Tamil Nadu to evaluate the efficacy of various botanicals against jassid Empoasca kerri Pruthi (Hemiptera: Cicadellidae) on groundnut under rainfed conditions. Among them, neem seed kernel extract (NSKE) @5% was found to be the most effective in both locations [Aruppukottai (65.45%) and Narikudi (64.98%)]. Similarly, neem oil @ 3% was found effective- Aruppukottai (55.27%) and Narikudi (56.46%). In terms of yield, the maximum yield (1523 and 1512 kg/ha) was obtained with NSKE @ 5% (910 and 927 kg/ha).
