The experiments were carried out at Indira Gandhi Agriculture University, Raipur, India to study the effect of neem based formulations against budfly (Dasyneura lini) infestation, grain yield, economics and oil content on linseed during rabi season. Linseed cv 'Neelum' was sown with ten treatments. Insecticidal treatments were applied twice at fortnightly interval starting from bud initiation stage. Budfly infestation was recorded at dough stage of the crop. The study revealed that application of NSKE 5 per cent was most effective against linseed bud fly with lowest bud damage of 14.15 per cent and highest grain yield of 1309.325 kg/ha and cost benefit ratio of 1:19.8 as against 30.69 per cent bud damage and 842.661 kg/ha grain yield in untreated control (UC). The data on test weight and oil content clearly indicated that there was no significant effect of any treatment on test weight and oil content of linseed. The test weight ranged from 9.10 gm in neem leaf extract (NLE) 2 per cent to 9.62 gm in neem seed extract (NSE) 5 per cent, as against 9.22 gm in UC, while the oil content in different protection levels ranged from 40.47 gm to 41.31 gm among nine protection levels as against 40.60 gm in UC.
