Abstract: Field experiment on the effect of organic and inorganic silicon amendments against yellow stem borer and leaf folder in rice revealed the superiority of CaSiO3 (Calcium silicate) @ 2t/ha and DAE (Diatomaceous earth) @ 0.45t/ha in arresting stem borer damage i.e. (0.00- 3.09%) dead heart and (0.35% & 0.69%) white ear head as against 2.34-11.43% dead heart and 4.47% white ear head in control. At vegetative and heading stages treatments resulted upto 92.17 and 84.56% reduction in borer damage in comparison to control.Similarly, in case of leaf folder, CaSiO3(Calcium silicate) @ 2t/ha and DAE (Diatomaceous earth) @ 0.45t/ha was successfully supress the infestation with a record of (0.00- 4.17% damaged leaf) in peak vegetative stage and (1.84% & 2.03%) damaged leaf in reproductive stage as against 3.73-8.55% damaged leaf in untreated control during the entire growth stage of the crop. Both the treatments are able to achieve 65.84 and 64.86% reduction in damage over control. In grain yield point of view both the treatments yielded more than 45.0q/ha which is significantly higher than untreated control (36.66q/ha).
