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). Staining can extend longitudinally (above and below) in the sapwood at a rate of 50–100cm per year. Since 2014 the LTOA has been leading on monitoring plane trees in London for the presence of canker stain, working closely with the Forestry Commission, Forest Research and several tree officers and managers to survey thousands of trees across the capital to meet the requirements necessary to retain Protected Zone Status This ensures that plane saplings can only be imported into the country from other areas which have been confirmed as being free of the disease. 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 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. This document is designed to inform and support tree officers and others working in the arboricultural industry should Ceratocystis be confirmed as having arrived in UK. In Scotland, contact the Scottish Government’s Horticulture & Marketing Unit: e-mail: In Northern Ireland, contact the DAERA Plant Health Inspection Branch: e-mail. Ceratocystis platani is a fungal pathogen which affects the genus Platanus and causes infected trees to die. London plane tree is attacked by a number of pests. 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 … The LTOA, under contract to the Forestry Commission, has been carrying out these surveys in Greater London since 2013. Infected sycamore and London planes have sparse foliage, small leaves, and elongated sunken cankers on the trunk and larger branches. 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. No effective chemical treatment is currently available. Please contact This email address is being protected from spambots.

In Europe, both Oriental plane and London plane trees are seriously threatened by the invasive fungal pathogen Ceratocystis platani (Walter) Engelbr. See the information on this disease in the "Common Plant Diseases" section. var path = 'hr' + 'ef' + '='; Whilst the fungus that causes canker stain of plane is not yet in the UK, it is now in Italy, France and Greece, and responsible for notable tree fatalities.The fungus can infect specimens through wounds in bark or stems as well as root-to-root contact. Contaminated tree surgeons' and forestry workers' gloves, ropes, clothes and boots might also spread the fungus. The second is called Canker stain of plane: Dealing with an outbreak. This tree is a cross between two sycamore species: Platanus occidentalis (American sycamore) and Platanus orientalis (Oriental plane). It produces resilient, long-lived spores which spread the disease, and these can persist in soil and on un-sterilised pruning and cutting tools. New requirements were therefore introduced for plane plants being moved anywhere in the EU/UK. 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.

Barbara stated that as an industry we need to “be proactive not reactive and work collaboratively”. It is a brief, practical document intended to bring relevant information together into once place and ensure that in the event of an outbreak in the UK we are well-placed to eradicate the disease before it becomes established. However, with the re-categorisation of this organism as a Union Quarantine Pest in December 2019, Protected Zone status was no longer applicable. 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. The new measures include more stringent requirements, and are based on the earlier Protected Zone arrangements. Few other tree species are as well suited to the role currently fulfilled by plane trees. 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.

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. The London Tree Officers Association (LTOA), has released a position statement outlining its concern about what it describes as ‘a number of significant pests and diseases threatening the health of London’s trees’. As the fungus spreads, it may disrupt the water transport system of the tree and cause cankers. Please note that TreeAlert and TreeCheck both require photographs to be uploaded. (See 'Origins and background' below.). London's plane trees could be under threat, warns the London Tree Officers Association (LTOA), from a new disease originating from the Continent. 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. No positive findings of C. platani were detected in any of the trees inspected. The LTOA has become a UK partner in the new Euphresco project Identification of Cryphonectria and Ceratocystis spp. The text is accompanied by colour photographs on almost every page and drawings/diagrams to assist identification and diagnosis. Plane trees account for 10% of all trees in London, making them one of the most densely populated breeds in the capital. In California, canker stain of Platanus acerifolia, caused by Ceratocystis fimbriata f. platani, appears to be confined to ornamental plantings and street trees in Modesto. Since the first report of the stain canker agent Ceratocystis platani in 2001 in Geneva, dieback of London plane trees (Platanus × acerifolia) has focused greater attention and an epidemiological monitoring has been implemented, as part of a compelling state directive for stain canker management.Genetic identification was carried out in order to ascertain the presence or … Click here to login.

Currently considered not to … Ceratocystis platani causes a disease in plane trees known as "Canker stain of plane" (UK English) or "Canker of sycamore" (US English). ), is a Quarantine parasite listed in Annex IIAII of Directive 2000/29/EC. 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. The London Tree Officers Association currently have 150 tree officers across London with 45 associate members who carry out annual plane tree surveillance. Canker stain: London plane and sycamore trees have sparse foliage, small leaves, and elongated sunken cankers on the trunk and larger branches. Of chief concern among these is the canker stain of plane (Ceratocystis platani) or CSP. occurring on sweet chestnut and Platanus spp. 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. The London plane {Platanus acerifolia Willd.) by entering through wounds and causing canker stain disease and tree death. The London plane tree (Platanus × acerifolia) is a very large deciduous tree that is quite resilient in urban conditions. Search terms in quotes will enable a more specific search e.g. Further guidance on biosecurity is available from the UK Government website. "Ash". More than half of the sites surveyed included potential hosts planted during the previous 10 years, and the sites ranged in size from a minimum of 20 to, in some cases, more than 200 trees. Some of the 'Additional resources' listed below also have illustrations. Inspections were undertaken at 53 sites across 28 London boroughs. Although C. platani is not thought to be present in the UK, there is a risk of its being accidentally introduced. Canker Stain of Plane INTERNATIONAL STUDY WORKSHOP Led by Prof Lucio Montecchio at the Tree Health Laboratory, CIPRAM & Neville Fay, Treework Seminars Director. The booklet was authored by international expert in Ceratocystis platani Professor Lucio Montecchio, of De Rebus Plantarum at the University of Padua. As mentioned, plane tree diseases tend to mirror those that afflict its close relative the Oriental plane and American sycamore tree. 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. It includes chapters detailing morphology and infection strategies, movement and spread, symptoms, practical survey tips, sample collection and fungal identification, the UK and Italian methods of prevention and control and a comprehensive list of references and further reading. Tolerant hybrid plane trees are being developed, and one variety has been released to the market in France. It spread rapidly through Italy and into France and Switzerland. It is spread predominantly by contaminated equipment being used on uninfected trees, although it can also be transported via root grafts.
