Abstract
The most important hardwood species now being planted in Uganda is Musizi (Maesopsiseminii Engl.), an indigenous tree. At present about 500 acres is planted each year and most of this in the areas surrounding Lake Victoria, but it is unlikely that this planting rate will be maintained since it forms part of a programme of re-afforesting encroachments, which is now nearly completed. In Kenya the Forest Department is planning an expansion of the existing Musizi plantations in the Kisumu area. Until late 1961 this species appeared to be quite free from any serious disease but reports were then received, from Several areas of Uganda, of what appeared to be a serious stem canker of young trees. These and subsequent similar outbreaks have been Investigated and it appears that the canker is caused by Fusarium solani (Martius) Sacco (perfect stage Nectria haematococca Berk. &Br.). Similar symptoms have been reported from Tanganyika [1].
