[2] In Gloucester, New Jersey, 87% of London plane trees had died by 1949. [4] The fungus is a wound parasite which rapidly infects plane trees, causing disruption of water movement, cankers and eventually death. Webster RK, Butler EE (1967) A morphological and biological concept of the species Ceratocystis fimbriata. Although it has not been detected in the UK, it has been reported in several European countries, with serious losses of 1) Identify (by means of pictures and an ID plate) both the tree as a whole and its main symptoms. Cankers elongate rapidly, and expand sideways slowly to girdle the branch or trunk. 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. Their habit of shedding bark allows them to cast off particulate pollutants, while their large, stiff leaves make them excellent shade trees. People receiving or handling imported plane material should be especially vigilant. It produces resilient, long-lived spores which spread the disease, and these can persist in soil and on un-sterilised pruning and cutting tools. Another serious ailment, this disease often causes trees to die within about 24 months of the first visible symptoms. In Europe, both Oriental plane and London plane trees are seriously threatened by the invasive fungal pathogen Ceratocystis platani (Walter) Engelbr. Ceratocystis platani is believed to be native to southeastern USA. Contaminated tree surgeons' and forestry workers' gloves, ropes, clothes and boots might also spread the fungus. 3) Screw a sterile increment borer tangentially (not radially as usually) to cross at least one necrosis. Ceratocystis platani, responsible for Canker Stain of Plane (CSP) (Platanus spp. 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. Thes… It originates from the eastern United States. In Europe, both Oriental plane and London plane trees are seriously threatened by the invasive fungal pathogen Ceratocystis platani (Walter) Engelbr. 742. Walter JM, Rex EG, Schreiber R (1952) The rate of progress and destructiveness of canker stain of plane-trees. SPREAD THROUGH EUROPE. 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’. 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. It was subsequently observed in plantations and in natural forests of Platanus occidentalis. Once infected, trees die within three to seven years. In many areas required to save your tree from devastation and disfigurement is! Ceratocystis Platani, responsible for Canker Stain of Plane (Platanus spp. ), is a Quarantine parasite listed in Annex IIAII of Directive 2000/29/EC. Some of the 'Additional resources' listed below also have illustrations. Ceratocystis fimbriata f. platani Please note that TreeAlert and TreeCheck both require photographs to be uploaded. However, this harsh pruning makes them vulnerable to canker stain and other fungal diseases, especially in the wet Spring months. "Ash". 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. 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 is the preferred route for suspected sightings made on trade premises, such as nurseries and garden centres. The disease has also been reported in California. It originates from the eastern United States. 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. 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. [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. 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. London plane trees have been popular urban specimens for nearly 400 years, and with good reason. The 42,000 plane trees (82% of the trees lining the banks) are being decimated by canker stain. Despite a range of preventive measures and careful felling of the affected trees, the whole population of plane trees east of Carcassonne is … [4], The disease was first reported in the USA in 1935 affecting Platanus × acerifolia. [4], Media related to Ceratocystis platani at Wikimedia Commons, Rapid Pest Risk Analysis for Ceratocystis platani, https://en.wikipedia.org/w/index.php?title=Ceratocystis_platani&oldid=976898866, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 September 2020, at 18:41. Phytopathology 42, 236-239. 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. [2] In Philadelphia the disease had killed 10,000 out of a total 150,000 trees by 1945. The disease mostly proliferates through human activity. C. platani is an aggressive fungal pathogen that attacks plane trees ( Platanus spp.) on major roots. It is a wound pathogen causing canker, wilt and then death of … 708880°—47 32 481. [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). It is a wound pathogen causing canker, wilt and then death of … Infected sycamore and London planes have sparse foliage, small leaves, and elongated sunken cankers on the trunk and larger branches. The response to discovery of a case in the UK would be guided by the Forestry Commission’s Contingency Plan. Resilient the London plane tree may be, it is not without its share of problems, specifically disease. Treating against plane tree canker stain. Ceratocystis platani is a quarantine organism causing canker stain of plane trees, a lethal disease of Platanus spp. What is plane wilt and what happens to the tree? 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 canker may at first just appear to be a darkened, flattened area on the wood. More recently, canker stain The epidemiologi-cal data highlight the destructiveness of the disease and its potential danger to all street plantings of Platanus acerifolia in Europe. 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. 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. See ‘Official action’ below for details of a survey conducted in 2014. 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. 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). 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. The new measures include more stringent requirements, and are based on the earlier Protected Zone arrangements.
