Fusarium circinatum, the causal agent of pine pitch canker (PPC), is currently one most important threats Pinus spp. globally. This pathogen known in many pine-growing regions, including natural and planted forests, can affect all life stages trees, from emerging seedlings to mature trees. Despite importance PPC, global distribution F. circinatum poorly documented, this problem also true hosts within countries that are affected. The aim study was review with a particular focus on Europe. We...
During the course of past three years, a new disease Pinus radiata , referred to as ‘Daño Foliar del Pino’ (DFP) has appeared in Arauco province Chile and subsequently spread other areas. The is typified by needle infections, exudation resin at bases brachyblasts and, younger trees, necrotic lesions cambium, which eventually girdle branches. causes death young seedlings mature trees can also succumb after few years successive infection, probably hastened opportunistic fungi such Diplodia...
Abstract Understanding the evolutionary histories of invasive species is critical to adopt appropriate management strategies, but this process can be exceedingly complex unravel. As illustrated in study worldwide invasion woodwasp S irex noctilio , population genetic analyses using coalescent‐based scenario testing together with B ayesian clustering and historical records provide opportunities address problem. The pest spread from its native E urasian range outhern H emisphere 1900s recently...
Summary Dothistroma needle blight ( DNB ), caused by the two fungi septosporum and D. pini, is a major disease of pines with worldwide distribution. Increases in incidence severity areas where has long been established notable range expansions have both recently observed. The aim this review was to assess relationship between , weather factors climate better understand possible underlying causes recent intensification disease. A substantial body literature shows that life cycles are closely...
Pitch canker, caused by Gibberella circinata (Fusarium circinatum), is currently regarded as one of the most serious diseases pines in world. The disease was first discovered south-eastern United States early 1900s and subsequently, has sporadic occurrences severe that area. More recently, appeared California where it causing a epidemic on native Pinus radiata, which international concern (Gordon et al., 2001). radiata forms basis extensive areas exotic forest plantation many countries...
Summary Dothistroma needle blight ( DNB ) caused by septosporum and pini is a damaging disease of pine in many countries. The led to the abandonment planting susceptible Pinus species parts Africa, Asia, Australasia, Europe North America. Although can be effectively controlled using copper fungicides, this chemical only routinely applied forests New Zealand Australia. Other management tactics aimed at making conditions less favourable for development, such as thinning or pruning, may...
Fusarium circinatum is a highly virulent invasive pathogen that causes the disease commonly known as pine pitch canker ( PPC ). On mature trees, most common symptoms of include resin bleeding, resinous cankers, wilting needles and dieback. In nurseries main are yellowish needles, foliage shoots. considered one important diseases conifers globally at least 60 species Pinus along with Pseudotsuga menziesii to be susceptible. Quarantine regulations crucial minimize risk new introductions into...
Abstract The Botryosphaeriaceae cause endophytic infections of leaves and bark various trees, including Eucalyptus, they apparently persist in this state for extended periods time. Under conditions stress, these fungi many different disease symptoms on which stem branch cankers die-back are the most prominent. Given their cryptic, nature, easily overlooked when moving seeds plants around world. It is, therefore, not surprising to see a growing number examples introductions into new...
The plantation and natural forests of South America have been highly impacted by native exotic pests in recent decades. interaction emerging invasive pests, climate change, timber markets will define the region’s forests, with significant but uncertain ecological changes economic losses expected. Southern Cone Forest Health Group (SCFHG), a joint ad hoc initiative run forest health professionals from Argentina, Brazil, Chile, Uruguay, aims to strengthen relationships between forestry...
Fusarium circinatum (Nirenberg and O’ Donnell) is the causal agent of pine pitch canker (PPC) disease, one most devastating forest diseases worldwide. Long-distance spread occurs mainly through movement infected seeds whereas at regional level, seedlings, substrates, or containers may play an important role in fungal dispersal. Invasion nurseries takes place via further can occur by planting contaminated especially due to possibility plants remaining symptomless. Once established, F. spreads...
Abstract Fusarium circinatum is a harmful pathogenic fungus mostly attacking Pinus species and also Pseudotsuga menziesii , causing cankers in trees of all ages, damping-off seedlings, mortality cuttings mother plants for clonal production. This listed as quarantine pest several parts the world trade potentially contaminated pine material such cuttings, seedlings or seeds restricted order to prevent its spread disease-free areas. Inspection plant often relies on DNA testing conventional...
Abstract Araucaria araucana , (commonly referred to as araucaria, pewen, or monkey puzzle tree) is an ancient conifer endemic the Chilean and Argentinian mountain ranges where it has a sacred relevance indigenous communities. During 2015, serious disease was noticed on trees of all ages in most natural distribution this iconic tree. Four areas were surveyed, important symptoms cankers branches stems resulting copious resin exudation. Trees monitored for period two years isolations made from...
Phytophthora pinifolia causes a needle and shoot disease in Pinus radiata, referred to as 'Daño Foliar del Pino'. This newly discovered requires intensive research efforts that necessitate the processing of large numbers samples for which accurate identification, often by people not experienced taxonomy, is required. The aim this study was, therefore, develop species-specific primers P. amplify internal transcribed spacer region ribosomal operon nuclear Ypt1 gene, respectively. were tested...
Glycaspis brimblecombei is an invasive insect pest of Eucalyptus that has spread rapidly around the world since its first report in California 1998. The now occurs on at least four continents where grown as a non-native plantation species. To characterize global routes invasion for this insect, we characterized sequences portion Cytochrome Oxidase 1 (COI) gene from 105 individuals and native range, including Australia, Brazil, Chile, La Réunion, Mauritius, South Africa United States. In...
