Four solid formulations of insecticides viz., Carbofuran, Phorate, Cartap @ 1kg. a.i. ha^-1 and Chlorpyriphos @ 0.5kg.a.i. ha^-1 along with the check, liquid formulation of monocrotophos @ 0.5 kg a.i. ha^-1 were applied against insect pest of rice during dry season 2009 and 2010. Result of the experiment conducted during dry season of 2009 revealed that Carbofuran treatment recorded lowest % of dead heart (4.2%), white ear head (4.5%), gundhibug damage (12.06% )and highest grain yield of 4.852 t ha^-1 in variety Jaya followed by the treatment phorate, cartap, chlorpyriphos and monocrotophos. During dry season 2010, also Carbofuran treatment recorded lowest % of DH (3.7%), WEH (4.2%), gundhibug damage (20.16%) and highest grain yield of 4.13 t ha^-1 followed by the treatment phorate, cartap, chlorpyriphos and monocrotophos. All the insecticides were found very effective against YSB and gundhibug in reducing their damage and increasing grain yield over control during both the years.
