Bioefficacy of botanicals and microbial insecticides was evaluated against aphid, Aphis gossypii Glover on coriander during Rabi 2011-12 and 2012-13. All the treatments were significantly superior to the untreated check. Among the tested biopesticides, neem oil (0.3%), NeemAzal-T/S 1 EC @ 0.0006 per cent and Gronim 0.30 EC @ 0.0006 per cent effectively managed the pest. The effectiveness was also reflected on yield of coriander seeds. The lowest (413 kg/ha) yield was obtained from ardusi leaf extract, which was at par with Verticillium lecanii (438.3 kg/ha) and Metarhizium anisopliae (453 kg/ha) treated plots.
