Abstract
the purpose of the present study was to examine the effect of chitin synthesis inhibitor (CSI) on glue shear strength of plywood made from rubber wood veneer.

Plywood samples were prepared using Phenol Formaldehyde (PF) resin mixed with lufenuron and diflubenzuron at 0.5, 1 & 2% concentration. Plywood made with this glue was tested for glue shear strength in dry, wet and mycological state as per Indian Standard.
From the results it was found that samples conformed the prescribed values of glue shear strength as per requisite standard. The study was limited to lab scale for testing the effect of CSI on the shear strength
