Abstract:
... In the mid-1970s, Mozambique embarked on several forestry projects to promote and establish large plantation areas with eucalypt trees. The planted species included Corymbia citriodora , Eucalyptus camaldulensis , E. saligna and E. tereticornis . Similar to other regions of the world, pests and pathogens pose a significant threat to eucalypt plantations in Mozambique, but little is known regarding ...

Abstract:
... Species of Teratosphaeria include some of the most important fungal pathogens of plantation-grown eucalypt trees. During routine disease surveys, symptoms and signs of leaf spot and blight were observed on the foliage of one-year-old E. grandis × E. urophylla hybrids in the Zululand region of KwaZulu-Natal, South Africa. These were distinct from those caused by the well-known and leaf-infecting fu ...

Abstract:
... Needle fungi have been extensively studied in conifers but rarely in Pinus radiata . Previous studies of P. radiata have been based on fungal isolation and not direct PCR detection from needles. This research was a component of a study examining factors linked to spring needle cast (SNC) in Tasmanian P. radiata plantations and aimed to identify as many as possible of the fungal species commonly as ...

Abstract:
... Zimbabwe embarked on planting Eucalyptus species in the early 1900s. Based on a robust breeding programme, it has become a major source of seed for other countries in and outside Africa. Tree health surveys conducted on Eucalyptus in some east and southern African countries over the past two decades have revealed several important fungal diseases that were previously not known in the region, but l ...

Abstract:
... The pitch canker pathogen, Fusarium circinatum , has major impacts on production in pine nurseries and plantations in South Africa. Thus far, efforts to reduce local spread have focused on rouging of infected pines and sanitation to eliminate local sources of inoculum. Although the host range of F. circinatum was thought to be limited to pines and Douglas-fir, recent studies in California indicate ...
