The workshop “Canker Stain of Plane, a Training Workshop in Italy” was co-organized by CIRPAM (Centro Interdipartimentale di Ricerca per il restauro, il recupero e la valorizzazione dei Parchi storici e degli Alberi Monumentali), Treework Environmental Practice and De Rebus Plantarum, PAN. Among them is London plane (Platanus x acerifolia, also known as Platanus x hispanica), which is widely grown in British towns and cities.

Canker stain, a disease caused by the fungus Ceratoycystis fimbriata f. platani has killed thousands of London plane trees (Plantanus X acerifolia) in northeastern United States since about 1926 (4). Infection commonly occurs through spores entering fresh wounds on healthy plane trees, such as those made by wind damage, birds, insects, and tree-care tools such as saws and knives. Plane tree planting material, other than seeds, intended for planting must now have been grown throughout their lifetime in a pest-free area, i.e. Canker stain, Ceratocystis fimbriata f. sp. by entering through wounds and causing canker stain disease and tree death. 2) Gently remove the bark to identify the necrosis edge by means of a sterile knife or gouge. This latter pathway is thought to be the main means by which the famous avenue of plane trees bordering the Canal du Midi in France became infected. (See 'Origins and background' below.). It is not known to be present in the UK. 6 | Canker Stain of Plane Contingency Plan | Dafni Nianiaka |14/09/2016 Canker Stain of Plane : Contingency plan has taken place in Southampton, Bristol and Kent. The example of canker stain of plane 22 . The trees are pruned during winter each year, to stop them becoming too large and giving them their unusual aesthetics. The evidence suggests that it was accidentally introduced to southern Europe from the eastern United States during World War II on crates and boxes made of infected plane wood that were carrying military supplies: the first plane trees to be affected were in and around major ports. Symptoms Panconesi (1981, 1999) provides a good description of the symptoms of canker stain. It is a wound parasite; a pathogen that enters the tree via existing cuts and damage. Once established, they require little additional care with the exception of watering. The London Tree Officers Association (LTOA) is pleased to announce the publication of two new guidance documents relating to canker stain of plane (CSP, Ceratocystis platani). Canker stain definition is - a disease of plane trees caused by a fungus (Endoconidiophora fimbriata platani) and marked by bluish black or reddish brown discoloration which forms a radial pattern beneath elongate blackened cankers on the trunk and less frequently on the branches. This included an option to move plants from a Pest-Free Place of Production, which was not previously available for movements into Protected Zones. Canker stain of plane is present in several European countries, including Albania, … 4 Canker stain of plane trees Journal of Plant Pathology (1999), 81 (1), 3-1 5 resistance to pruning, pollution, and, not least, anthrac- nose (Gnomonia platani Kleb. The disease is characterized by blackened, elongate cankers having. Canker stain of plane is a disease which can affect several species of plane trees (trees in the Platanus genus). On 21 April 2020, following the spread of the disease into northern France, new national measures came into effect to strengthen these protections further. Until December 2019 the UK had European Union Protected Zone status for plane material to provide extra safeguards against accidental introductions of this disease on imported plane plants or wood. Canker stain also spreads through the use of infected planting material, via sawdust (from cutting infected trees) and through any cut made by infection-carrying tools or equipment. However, this harsh pruning makes them vulnerable to canker stain and other fungal diseases, especially in the wet Spring months. Thes… See ‘Official action’ below for details of a survey conducted in 2014. , The disease was first found in Europe in Marseille, France in 1945, and is believed to have been transported there by US troops during Operation Dragoon towards the end of World War II. The rules set out in this guide help prevent the diseases Xylella fastidiosa, Ceratocystis platani (canker stain or plane) and Candidatus Phytoplasma ulmi (elm yellows) coming into the UK. What is plane wilt and what happens to the tree? Canker stain of plane Dealing with an outbreak A guidance note for tree officers/managers and contractors 1 Introduction 1.1 Ceratocystis platani (canker stain of plane, or CSP) is a fungal vascular pathogen which affects the genus Platanus, causing infected trees to die. (The term pest-free applies to disease-causing organisms as well as insect pests.). This pathogen poses a significant risk to plane trees in the UK because plane is widely used as an urban amenity species in parks and public gardens, and alongside streets and roads. When the soft outer layers of wood underneath the bark are infected, vessels in the vascular system are blocked from transporting water and energy and cause the sudden wilting of the tree. These spots are very important in diagnosing canker stain infection even when the tree has been invisibly infected through the roots (Panconesi, 1981). In September 2003, dead and dying plane trees (Platanus orientalis ) were observed in seven different localities of the Messinia prefecture of the south‐western Peloponnese, Greece.Cankers were found on both trunks and branches. Beneath the cankers, the wood is … Canker stain definition is - a disease of plane trees caused by a fungus (Endoconidiophora fimbriata platani) and marked by bluish black or reddish brown discoloration which forms a radial pattern beneath elongate blackened cankers on the trunk and less frequently on the branches. SPREAD THROUGH EUROPE. New requirements were therefore introduced for plane plants being moved anywhere in the EU/UK. SLB is a known vector of Ceratocystis Fimbriata, also known as “Canker Stain”. However, with the re-categorisation of this organism as a Union Quarantine Pest in December 2019, Protected Zone status was no longer applicable. Tolerant hybrid plane trees are being developed, and one variety has been released to the market in France. The most distinctive symptom, however, is the bluish-. Although it has not been detected in the UK, it has been reported in several European countries, with serious losses of 10. The first is called Canker stain of plane: A guide to prevention and is a brief reminder for tree officers and contractors of the importance of biosecurity in the fight to prevent Ceratocystis from entering the UK.  In Italy and the south-east of France the disease has caused serious losses. Its symptoms include reduced foliage, stunted leaf growth, and the appearance of elongated, sunken cankers on the trunk and older branches. (differing from the species only in its pathogenicity to Platanus spp. Search terms in quotes will enable a more specific search e.g. an area free of C. platani. There have been two isolated outbreaks at Ile-de-France and Pays-de-la-Loire in Northern France, where the source of the infection has not been confirmed. The fungus was introduced by the American landings at Provence, in the south of France. However, this harsh pruning makes them vulnerable to canker stain and other fungal diseases, especially in the wet Spring months. Cankers elongate rapidly, and expand sideways slowly to girdle the branch or trunk. Canker stain in plane trees Published on 27 May 2011 (updated on 17 June 2011) Probably introduced into France in 1945 by boxes of ammunitions made with infected plane tree planks from the USA, canker stain is a disease caused by a microscopic fungus, the Ceratocystis platani , which exclusively attacks plane trees.
