Online published on 21 July, 2020. 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).
