Lindane and parathion at 0.1 per cent ai. were the best treatments. The addition of superior white oil 0.1 per cent to insecticide mixtures enhanced the effectiveness of treatment. Carbaryl 0.1 per cent a.i. plus superior white oil 1.0 per cent and carbaryl 0.7 per cent a.i. plus superior white oil 1.0 per cent maintained plants substantially free of S. celebensis for ten and 22 days respectively. There was no evidence of phytotoxicity in any of the treatments.
