Most cocoa plantations in the eastern region of Sierra Leone are ageing, with a gradual drop in the yield. The main problem is due to high pest and disease incidence. A trial to determine the effect of Kocide 101 (copper oxide) and Kokotine (Lindane) on rehabilitating (bringing back into bearing) the old plantations was carried out in a site spreading in the three districts of Kailahun, Kenema, and Kono. The profitability analysis showed that a rehabilitatedtreeproduced about 94% more healthy pods than a non‐rehabilitated tree.
