Diseases of plantation Eucalyptus in the Republic of Congo

Plantation forestry, based on Eucalyptus species and clones, has been practised in the Republic of Congo since the early 1950s. A survey of plantations in the Pointe-Noire area undertaken in 1998 identified the diseases affecting plantation eucalypts. These included Cryphonectria canker, Botryosphae...

Summary:Plantation forestry, based on Eucalyptus species and clones, has been practised in the Republic of Congo since the early 1950s. A survey of plantations in the Pointe-Noire area undertaken in 1998 identified the diseases affecting plantation eucalypts. These included Cryphonectria canker, Botryosphaeria canker, Cylindrocladium leaf blight and bacterial wilt. A new and serious disease of eucalypts, caused by Ceratocystis fimbriata, was reported for the first time during this survey. A number of secondary, opportunistic fungi were also isolated from diseased tissue. We believe that the impact of these diseases will increase in future, as clonal forestry is practised more extensively. Disease management programmes should thus be established to reduce losses.
