Abstract
The Cape Saint Paul Wilt Disease (CSPWD), a lethal-yellowing type disease of coconut has been in Ghana since 1932. Aerial and/or ground surveys were undertaken to assess the current status of the disease spread. The survey showed that the spread of the disease for the past 5 years has mainly been the expansion of existing foci. However, new outbreaks were identified at Glidzi in the Volta, Bawjiase and Efutu Breman in Central regions. After the resurgence in the Volta region in 1995, the Woe-Tegbi-Dzelukope corridor has remained endemic, but less aggressive. Pockets of healthy groves remain along all the coastline and inland of known disease zones. Eradication of diseased palms at Ampain focus lying just about 60 km to the Ivorian border, and disease situations on new replanting with MYD × VTT hybrid are discussed.

This paper reports and discusses the aerial surveillance, current disease distribution in the Volta, Central and Western regions, containment of the disease at Ampain as well as the disease situation on new replanting plots with the hybrid, MYD × VTT
14 Plots infected in Central Region Plots infected in Western Region
Summary
The Cape Saint Paul Wilt Disease (CSPWD), a lethal-yellowing type disease of coconut has been in Ghana since 1932. The second is a “jump spread” whereby the disease appears at a spot remote from a known focus This is followed by a local spread in all directions. In 2006 and 2007, an aerial surveillance was conducted to have a quick view of the extent of the disease spread in the Western region. These were the only occasions ever of monitoring the CSPWD spread with an aircraft in the country. This paper reports and discusses the aerial surveillance, current disease distribution in the Volta, Central and Western regions, containment of the disease at Ampain as well as the disease situation on new replanting plots with the hybrid, MYD × VTT
