The present experiment was conducted to assess the effectiveness of plant oils for increasing the efficacy of insecticides and acaricides under both laboratory and field condition at Main Agricultural Research Station, University of Agricultural Sciences, Raichur during 2014-15. Among the plant oils used, castor oil emerged as the best material for increasing the efficacy of pesticides against sucking pests of chilli. The mite population at lab condition was influenced at different plant oils indicated that the treatment castor oil + dicofol proved to be superior among all the treatments with least mite population. The mortality levels recorded at different intervals were 56.67 per cent, 70 per cent, 83 per cent and 93.33 per cent at 24, 48, 72 and 96 hours, after treatment respectively. Under field condition also, the treatment castor oil + dicofol recorded lowest population counts.
