The pooled results revealed that the cholrantraniliprole was the most effective insecticide against major pests of rice with yellow stem borer showing 5.15% dead and 14.37% white ears; gall midge, 1.82% silver shoot and leaf folder exhibiting 1.33% leaf damage, respectively and recording highest grain yield of 2,899 kg/ha amongst treatments. Among the plant oils, eucalyptus was found effective against stem borer with low incidence of dead hearts (4.96%) and camphor oil was effective against whorlmaggot (0.69% damaged leaves) and stem borer (19.59% white ear). Incidence of gallmidge (5.38% silver shoot) and leaf folder (14.18% damaged leaves) was lower in neemazal treated plots respectively.
