London plane and sycamore trees have sparse foliage, small leaves, and elongated sunken cankers on the trunk and larger branches. Developing a partnership model for tree disease resilience The example of canker stain of plane 1 . The new measures include more stringent requirements, and are based on the earlier Protected Zone arrangements. ), is a Quarantine parasite listed in Annex IIAII of Directive 2000/29/EC. Search terms in quotes will enable a more specific search e.g. [4], In 2006 C. platani was identified as the cause of plane tree death along the Canal du Midi, a UNESCO world heritage site in France. In subsequent years the disease was reported in most Atlantic seaboard states. 742. It is a wound pathogen causing canker, wilt and then death of … fastidiosa from elm does not infect sycamore or vice versa. It is a wound pathogen causing canker, wilt and then death of … Cankers elongate rapidly, and expand sideways slowly to girdle the branch or trunk. 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. A core strand will focus on tree diseases, and tree and soil health and resilience. The 42,000 plane trees (82% of the trees lining the banks) are being decimated by canker stain. Treating against plane tree canker stain. Lethal cankers on London plane trees and sycamore seen first as a black or brown coloration, generally in a lens-shaped pattern, on the smooth yellow or green bark. The canker stain disease is caused by the fungus Ceratocystis fimbriata; it is able to produce suffering and even to bring to death those trees. [4] The fungus is a wound parasite which rapidly infects plane trees, causing disruption of water movement, cankers and eventually death. Ceratocystis Platani, responsible for Canker Stain of Plane (Platanus spp. Read our operational statement about COVID-19, Not present in United KingdomNotifiable – see ‘Report a sighting’ belowScientific name of causal agent - Ceratocystis platani. an area free of C. platani. The disease has also been known as plane tree wilt. Resilient the London plane tree may be, it is not without its share of problems, specifically disease. 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). Ceratocystis platani is the causal agent of canker stain of plane trees, a lethal disease able to kill mature trees in one or two successive growing seasons. 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. This disease affects the water-conducting vessels of plane trees causing wilting of the leaves and staining of the wood. Ceratocystis platani is believed to be native to southeastern USA. 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. 2) Gently remove the bark to identify the necrosis edge by means of a sterile knife or gouge. [4] The canal is lined with around 42,000 plane trees and up to 2011, around 2,500 trees had been felled, destroyed and replaced with disease-resistant planes. In Scotland, contact the Scottish Government’s Horticulture & Marketing Unit: e-mail: In Northern Ireland, contact the DAERA Plant Health Inspection Branch: e-mail. 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. Of the Canal du Midi’s 42,000 plane trees, 25,000 have been cut down in 12 years. The fungus was introduced by the American landings at Provence, in the south of France. 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. The disease’s presence in our near neighbours and trading partners in continental Europe heightens the risk of its being accidentally introduced into the UK. [1], Ceratocystis platani causes a disease in plane trees known as "Canker stain of plane" (UK English) or "Canker of sycamore" (US English). They spread and in short notice will kill the plane tree. However, this harsh pruning makes them vulnerable to canker stain and other fungal diseases, especially in the wet Spring months. the European & Mediterranean Plant Protection Organization (EPPO) database, daera-ni.gov.uk/topics/plant-and-tree-health/about-plant-and-tree-health, EU Exit and tree and forestry pests and diseases, plants, seeds, cuttings or other planting material, Forestry Commission’s Plant Health Service, UK Plant Health Risk Register entry, including pest risk analysis, American Phytopathological Society article, Anthracnose of plane (Apiognomonia veneta), Asian longhorn beetle (Anoplophora glabripennis), Bleeding Canker of Horse Chestnut (Pseudomonas syringae pv aesculi), Canker stain of plane (Ceratocystis platani), Citrus longhorn beetle (Anoplophora chinensis), Conifer root and butt rot (Heterobasidion annosum), Dothistroma needle blight (Dothistroma septosporum), Elbow-patch crust of plane (Fomitiporia punctata), Elm yellows (Candidatus Phytoplasma ulmi), Emerald ash borer beetle (Agrilus planipennis), Great spruce bark beetle (Dendroctonus micans), Horse chestnut leaf miner (Cameraria ohridella), Larger eight-toothed European spruce bark beetle (Ips typographus), Neonectria canker of fir (Neonectria neomacrospora), Oak processionary moth (Thaumetopoea processionea), Oriental chestnut gall wasp (Dryocosmus kuriphilus), Phytophthora austrocedri disease of juniper and cypress, Phytophthora disease of alder (Phytophthora alni), Pine processionary moth (Thaumetopoea pityocampa), Pitch canker of pine (Fusarium circinatum), Red-necked longhorn beetle (Aromia bungii), Siberian silk moth (Dendrolimus sibiricus), Sweet chestnut blight (Cryphonectria parasitica), Thousand cankers disease (Geosmithia morbida), Two-lined chestnut borer (Agrilus bilineatus), Two-spotted oak buprestid (Agrilus biguttatus), Western, eastern and black-headed budworms, Report suspected sightings in Great Britain to us using, Report suspected sightings in Northern Ireland to the Irish plant health authorities using, In England and Wales, contact the local office of the Plant Health & Seeds Inspectorate (PHSI) of the. 708880°—47 32 481. Ceratocystis fimbriata f. platani Canker Stain, a disease caused by the fungus ceratocystis platani, has had an especially serious effect on European plane trees in recent decades. Walter JM (1946) Canker stain of plane trees. Plane wilt (also known as canker stain of plane) is a serious disease of plane trees (Platanus spp.) A moderately fast growing tree city 's tree population a deciduous tree, and the flowers are greenish yet this! Canker stains is a lethal fungal affliction of the sycamore tree, caused by the Ceratocystis fimbriata. This fungal disease is not present in Australia, however, if established it would spread rapidly – mostly affecting London Plane Trees. Beneath the cankers, the wood is stained bluish black or reddish brown. A report commissioned by former prime minister François Fillon has delivered its verdict on the scale of works required to restore the Canal du Midi‘s priceless tree canopy. Phytopathology 42, 236-239. The most distinctive symptom, however, is the bluish-. The canker stain disease is caused by the fungus Ceratocystis fimbriata; it is able to produce suffering and even to bring to death those trees. Sycamore Canker Stain Sycamore canker stain is a fungal disease that affects sycamores and London plane trees in California. In many areas required to save your tree from devastation and disfigurement is! Walter JM (1946) Canker stain of plane trees. Infected trees exhibit sparse chlorotic (yellowing) foliage, and sometimes sunken, elongated or lens-shaped cankers (like oozing sores) in the bark (below). Canker Stain. The disease mostly proliferates through human activity. SLB is a known vector of Ceratocystis Fimbriata, also known as “Canker Stain”. We therefore encourage tree and ground-care professionals, plane tree owners and managers, and the public, to be vigilant for signs of it and to report suspected sightings immediately. 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. & T.C. The example of canker stain of plane 22 . Their habit of shedding bark allows them to cast off particulate pollutants, while their large, stiff leaves make them excellent shade trees. Visit the UK Government website for an explanation of the regulations applying to the importation of: The C. platani fungus is thought to have originated in North America. The new requirements apply to imports to the UK from Albania, Armenia, Switzerland, Turkey, and the United States and the EU-27. When left in ideal conditions, Plane trees can live to … London plane is a naturally occurring hybrid, and its parent species, eastern or Oriental plane (P. orientalis) and western or American plane (P. occidentalis), can also be infected. 10. The canker stain disease is caused by the fungus Ceratocystis fimbriata; it is able to produce suffering and even to bring to death those trees. Ceratocystis platani is a fungus that causes a disease on plane trees in the genus Platanus. 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 of plane is a disease which can affect several species of plane trees (trees in the Platanus genus). It is seriously affecting the famous avenue of thousands of plane trees lining the banks of France’s Canal du Midi, and many have had to be felled. Another serious ailment, this disease often causes trees to die within about 24 months of the first visible symptoms. The disease is characterized by blackened, elongate cankers having. The pathogen is a quarantine organism and has a negative impact on anthropogenic and natural populations of plane trees. Contaminated sawdust produced during pruning and sanitation fellings can contribute to disease spread. Beneath the cankers, the wood is stained bluish black or reddish brown in a wedge-shape (when viewed in cross section) with the point of the wedge extending toward the center of the trunk or branch. Italian Society of Arboriculture Milan 2- 5 July 2015, Parc Sempione, Milan, Development of a partnership model Lucio Montecchio & Neville Fay 2 . (Please note: where contact details in the Pest Alert differ from those given on this page, please use those on this page.). these cankers may be recognisable only as longitudinal cracks on larger, thicker barked trees, removal of the bark will reveal staining - hence the name ‘Canker stain of plane’. [2] It was elevated to the level of a new species in 2005. [2] At Forte dei Marmi, one of the oldest infection centres in Italy, 90% of all plane trees died of the disease in the twenty-year period from 1972-1991. The most devastating of these diseases is called canker stain, which is caused by the fungus Ceratocystis platani. Its symptoms include reduced foliage, stunted leaf growth, and the appearance of elongated, sunken cankers on the trunk and older branches. They are remarkably hardy and tolerant of a variety of conditions. In all cases, provide precise details of the location and, if possible, clear, well lit, close-up photographs of the symptoms. Ceratocystis platani is a quarantine organism causing canker stain of plane trees, a lethal disease of Platanus spp. The 42,000 plane trees (82% of the trees lining the banks) are being decimated by canker stain. most commonly on trunks, less frequently on branches, and occasionally. Please note that TreeAlert and TreeCheck both require photographs to be uploaded. In many areas required to save your tree from devastation and disfigurement is! It spread rapidly through Italy and into France and Switzerland. What is plane wilt and what happens to the tree? The cankers occur. 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. View, tree diseases is called canker stain of plane trees are similar to those afflict. Webster RK, Butler EE (1967) A morphological and biological concept of the species Ceratocystis fimbriata. [2], 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. They are valued for their shade, amenity value and toleration of air pollution and water shortages. [2], The disease is caused by the phytotoxin cerato-platanin, which occurs in the cell wall of C. platani, as well as other Dikarya, and is involved in molecular fungus-host interactions. Current chemical or biological controls do not effectively manage C. platani, so new preventive methods need to be developed in order to limit this pathogen spreading. [2] In Italy and the south-east of France the disease has caused serious losses. It is thought to be native to south-eastern USA and has spread throughout urban P. acerifolia populations planted in the large cities of the East coast. [R.A.M., 30, p. 244]), infection is believed to have appeared for the first time in 1926. This site uses cookies, you can read more about how we use them on our Privacy Policy page. As of now, there is no know cure. ), one of the most widely used ornamental species world‐wide, are seriously threatened by the invasive fungal pathogen Ceratocystis … Distribution. On behalf of the Forestry Commission, the London Tree Officers' Association (LTOA) surveyed 2,979 London plane trees in 2014 for symptoms of C. platani infection. Endoconidiophora fimbriata f. platani. The images below, show the cracking visible as part of the canker, as well as the dark-coloured spots, characteristic of the fungus. In the oldest known centre, at Gloucester, New Jersey, of the canker stain disease of the London plane tree (Platanus acerifolia), caused by Endoconidiophora [Ceratocystis] fimbriata f. platani Walter n.f. Canker stain London plane and sycamore trees have sparse foliage, small leaves, and elongated sunken cankers on the trunk and larger branches. 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 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. It produces resilient, long-lived spores which spread the disease, and these can persist in soil and on un-sterilised pruning and cutting tools. 3) Screw a sterile increment borer tangentially (not radially as usually) to cross at least one necrosis. The trees are pruned during winter each year, to stop them becoming too large and giving them their unusual aesthetics. on major roots. It was subsequently observed in plantations and in natural forests of Platanus occidentalis. The canker may at first just appear to be a darkened, flattened area on the wood. It is a wound parasite; a pathogen that enters the tree via existing cuts and damage. C. platani is an aggressive fungal pathogen that attacks plane trees ( Platanus spp.) Alternatively, suspected sightings can be made directly to the relevant plant health authority. The disease has long been known to destroy plane trees in southern United States as well (3). Contaminated tree surgeons' and forestry workers' gloves, ropes, clothes and boots might also spread the fungus. The pathogen is now present in most of Italy. Canker stain of plane is present in several European countries, including Albania, … This is the preferred route for suspected sightings made on trade premises, such as nurseries and garden centres. [4] The disease can cause sudden death of a portion of the crown, and trees of 30–40 cm diameter may die within 2–3 years of infection. Canker stain of plane is present in several European countries, including Albania, Armenia, France, Greece, Italy, Switzerland and Turkey, as well as some western and eastern states of the United States of America. The disease has also been reported in California. 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. Webster RK, Butler EE (1967) A morphological and biological concept of the species Ceratocystis fimbriata. (differing from the species only in its pathogenicity to Platanus spp. Further guidance on biosecurity is available from the UK Government website. 2) Gently remove the bark to identify the necrosis edge by means of a sterile knife or gouge. [2] In Gloucester, New Jersey, 87% of London plane trees had died by 1949. The canker stain disease is caused by the fungus Ceratocystis fimbriata; it is able to produce suffering and even to bring to death those trees. 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. [2] In Marseille, where the first phase of infection started in 1945, 1850 Plane trees were killed between 1960 and 1972 (about 13% of the initial population). Ceratocystis platani causes a disease in plane trees known as "Canker stain of plane" (UK English) or "Canker of sycamore" (US English). They are remarkably hardy and tolerant of a variety of conditions. Despite a range of preventive measures and careful felling of the affected trees, the whole population of plane trees east of Carcassonne is … [2] Since then, hundreds of dead and dying trees have been found along streams and rivers in southwestern Greece, and many ornamental trees have died in residential and recreational areas. It is not known to be present in the UK. Willd. canker stain of plane trees caused by Ceratocystis fim-briata f.sp. 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. Another serious ailment, this disease often causes trees to die within about 24 months of the first visible symptoms. [2], Ceratocystis platani was first detected in Greece in 2003. 742. Although it has not been detected in the UK, it has been reported in several European countries, with serious losses of Canker stain, Ceratocystis fimbriata f. sp. New requirements were therefore introduced for plane plants being moved anywhere in the EU/UK. Lethal cankers on London plane trees and sycamore seen first as a black or brown coloration, generally in a lens-shaped pattern, on the smooth yellow or green bark. Staining can extend longitudinally (above and below) in the sapwood at a rate of 50–100cm per year. Walter JM, Rex EG, Schreiber R (1952) The rate of progress and destructiveness of canker stain of plane-trees. US Department of Agriculture Circular No. Although its progress through France was initially slower, the fungus has been spreading northwards at a much faster rate in recent years. Walter JM, Rex EG, Schreiber R (1952) The rate of progress and destructiveness of canker stain of plane-trees. The disease can also be transferred through root contacts between neighbouring trees, and by water. It is caused by the ascomycete fungus Ceratocystis platani (C. platani), which was formerly known as Ceratocystis platani f. platani and Ceratocystis fimbriata s. sp. See ‘Official action’ below for details of a survey conducted in 2014. The ascomycete fungus Ceratocystis platani causes canker stain, also known as plane tree wilt, on several plane species, including London plane (Platanus x acerifolia) and its parents, P. orientalis and P. occidentalis. & T.C. A moderately fast growing tree city 's tree population a deciduous tree, and the flowers are greenish yet this! C. platani can infect most species of plane trees. This knowledge mainly concerns the morphology, taxonomy and biology of the fungus and relations between host and parasite. 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. Canker Stain of Planetrees by JAMES M. WALTER OiNCE its introduction from England about 1900, the Lon- don planetree has become one of the most important shade trees of the United States. Its spread can therefore be limited by sourcing plant material from regions free of the disease, and by practising strict biosecurity (plant hygiene), such as disinfecting tools with alcohol before moving on to the next tree. "Ash". 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. causes canker stain, also known as plane tree wilt, on several plane species, including London plane (Platanus x acerifolia) and its parents, P. orientalis and P. occidentalis. 10. 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). These stains turn brown and make the bark burst. Beneath the cankers, the wood is … In short, the legislation effectively banned the movement of plane plants into the UK unless they had been grown in an area free of canker stain of plane, and were accompanied by a plant passport certifying this. More-detailed information about its distribution is available from the European & Mediterranean Plant Protection Organization (EPPO) database. by entering through wounds and causing canker stain disease and tree death. Of the Canal du Midi’s 42,000 plane trees, 25,000 have been cut down in 12 years. For unknown reasons the disease seems to have become less significant in the United States in recent years, but Greece and south-eastern France have experienced serious losses of shade trees. The fungus is transferred from tree to tree by insects that feed on the sap. platani. Larger agricultural and landscaping equipment such as terracing machinery should be jet-washed with water to remove any contaminated soil before moving to new sites. On 21 April 2020, following the spread of the disease into northern France, new national measures came into effect to strengthen these protections further. complex as Ceratocystis fimbriata f. Ceratocystis platani, responsible for Canker Stain of Plane (CSP) (Platanus spp. ), is a Quarantine parasite listed in Annex IIAII of Directive 2000/29/EC. The disease has long been known to destroy plane trees in southern United … The response to discovery of a case in the UK would be guided by the Forestry Commission’s Contingency Plan. 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. However, with the re-categorisation of this organism as a Union Quarantine Pest in December 2019, Protected Zone status was no longer applicable. (The term pest-free applies to disease-causing organisms as well as insect pests.). Ceratocystis platani causes canker stain of plane trees, and it represents a serious disease of Platanus spp. Cankers elongate rapidly, and expand sideways slowly to girdle the branch or trunk. platani. 3) Screw a sterile increment borer tangentially (not radially as usually) to cross at least one necrosis. Phytopathology 42, 236-239. Ceratocystis platani causes a disease in plane trees known as "Canker stain of plane" (UK English) or "Canker of sycamore" (US English). [3], Oriental plane (Platanus orientalis) is considered highly susceptible to the fungus; American sycamore (Platanus occidentalis) probably coevolved with the fungus and is relatively resistant, while the hybrid London plane (Platanus × acerifolia) is generally intermediate in resistance between its parents. The epidemiologi-cal data highlight the destructiveness of the disease and its potential danger to all street plantings of Platanus acerifolia in Europe. 1) Identify (by means of pictures and an ID plate) both the tree as a whole and its main symptoms. It is a wound pathogen causing canker, wilt and then death of infected trees. 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. [1] The fungus was previously considered to be part of the Ceratocystis fimbriata species There are unconfirmed reports from some other European countries. It forms violet blue stains that are necrotic, and this canker wedges itself in the wood, on the trunk and branches and cut off the sap flow. Thes… The rules set out in this guide help prevent the diseases Xylella fastidiosa, Ceratocystis platani (canker stain or plane) and Candidatus Phytoplasma ulmi … The inner bark and the cambial region of the cankered area were discoloured bluish‐black and the underlying wood stained dark reddish‐brown to bluish‐black. 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. In Europe, both Oriental plane ( Platanus orientalis L.), a native species with south eastern range, and London plane ( Platanus × acerifolia (Ait.)
