Atherigona sp. has become the serious pest of Sorghum in India and abroad. Its occurrence has been recorded on wheat. The damage is caused by maggots which penetrate into the stem and attack the apical meristem causing 'deadheart' similar to stemborer attack in sugarcane. The life cycle is very short and the maggots can attack only young seedlings and shoots. An experiment was conducted in a randomised block design with 14 treatments. and four replications. The treatments were granules of Phorate 10%, Lindane 10%, Endrin 2% each applied in three different ways i. e. (i) below seed, (ii) above seed and (iii) on the soil surface respectively and emulsion sprays of demeton methyl, dieldrin, diazinon and dimethoate applied on the surface in the form of a spray at the rate of 50 ml a. i. per 1000 ft. row length. Granules of phorate and lindane were applied at the rate of 50 ga. i. per 1000 ft. row length
