This study investigates the efficacy of chemically modified bone adhesive as a formaldehyde‐free binder for wood‐based industries. Two different types of adhesive are formulated after chemical modification of bone powder using sulfuric acid (0.5 m) and polyvinyl acetate (PVA). Gel time, solid content, Fourier‐transform infrared spectroscopy (FT‐IR), thermogravimetric analysis (TGA), viscosity, and single lap joint test for shear strength are analyzed in order to assess the adhesive properties. To analyze the efficacy of the formulated adhesive, particleboards are fabricated using boiled and unboiled sugarcane bagasse. The physical and mechanical properties of the fabricated panels are measured following ASTM standards. It is found that adhesive Type C (T‐C) has the shortest gel time of 4.2 min for the highest shear strength, i.e., 5.31 MPa. The particleboard (BTC‐2) fabricated using T‐C adhesive shows a highest density of 0.73 g cm−3, a modulus of elasticity (MOE) of 1975 N mm−2, and a modulus of rupture (MOR) of 11.80 N mm−2. The dimensional stability of the fabricated particleboards does not follow the standard requirements; however, further study might be helpful for using the chemically modified bone adhesive as a biobased adhesive.

A research work based on eco-friendly management practices was undertaken at Agro-technology research field, Khulna University containing five treatments viz. Neem (Azadirachta indicia A. Juss.), Netting, Pheromone, Mahogoni (Swietenia mahagoni L.) and untreated control in RCBD with four replications aiming to evaluate their efficacy against tomato fruit borer, Helicoverpa armigera Hubner infestation. Data were taken on tomato fruit infestation (%), number of holes and number of larvae per infested fruit. All eco-friendly management practices had remarkable action against the tomato fruit borer, of which Netting claimed the highest position to protect tomato fruit borer infestation compared to other management practices whereas the highest insect infestation took place in untreated control. So, to infer, Netting is very promising and efficient tool in controlling tomato fruit borer for safe and quality tomato production.
