Effect of organic and inorganic silicon amendments against yellow stem borer (Scirpophaga incertulas Walker) and leaf folder (Cnaphalocrocis medinalis Guenee) of rice in Costal Odisha

Ipsita OP Mishra, SK Panda and AB Dash

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).
