Vascular-streak dieback disease of cocoa
Abstract
Vascular-streak dieback disease (VSD) is the most damaging disease of the shoots and branches of cocoa in Papua New Guinea. It occurs in this country and other parts of South-East Asia but not in Africa, South America or the Pacific Islands. Not all of Papua New Guinea's cocoa is affected. North Solomons, New Ireland, Manus, Bali Witu Islands and the Milne Bay Islands do not have VSD.
