Platanus is a kind of plants of family of Platanaceae . monumental trees are suitable as ornamental plants to decorate streets, parks and large gardens, and urban design because of the high resistance smog of big cities.
best known species of Platanus

The species now wild in Italy, Fr hybrida commonly known as common plantain is a hybrid between Platanus occidentalis Platanus orientalis and. The Platanus occidentalis L.
known as West Willow, is a native of North America, also commonly called Platano American has 3-5 lobed leaves little marked, seed heads solitary door peeps, achenes surmounted by a short style, cultivated for ornamental purposes in Italy

is used as an ornamental tree for avenues, parks and large gardens The timber made from it is heavy (p. sp. 1.00 from fresh, aged 0.67, 0.62 dry), durable, is used for furniture, plywood, firewood
Adversity
Insects:
- Lepidoptera:
Bombich - larvae Lasiocampa Quercus L. (Lasiocampidae) erode the leaf blade causing severe defoliation
Bucephalus - larvae Phalera Bucephala L. (Notodontidae) attack the leaves, leaving intact only the ribs
Rodilegno white - the larvae of L. Zeuzera pyrin cause serious damage by digging tunnels in the trunks and branches slender
- beetle - adults and larvae of the beetle Scolytus multistriatus Marsh. feed on buds and tender bark, with serious phenomena of decay of the plant and yellowing of the leaves, the females dig tunnels between the bark and lay the wood, the larvae dig new tunnels perpendicular to the mother tongue, emerging through a hole in cortex in the adult stage, may be carriers of fungal diseases
Mushrooms:
- Carie - the attack of Polyporus sp., Trametes sp. Fomes sp. reduced to a pile of wood spongy and crumbly, whitish or brownish, depending on the degradation of cellulose and lignin interests, on the surface of the trunk appear carpophores shelf or hoof-shaped, gray-yellowish caseous in consistency and maturity woody
- Seccume leaf - the attack Gnomonia veneta (Sacc. et Speg.) Kleb. Case browning on the leaves of the lamina, in correspondence with the prime rib with the appearance of blackish dots, on the twigs causes a shortening of internodes with the formation of tubercles
- Cancer colorful - the Ascomycota fungus Ceratocystis fimbriata is a dangerous parasite originating from America and arrived in Europe during World War II (Through the plane of wooden crates in which the ammunition were landed at Trieste). The infection affects all plant parts (stems, foliage and roots) and is transmitted by direct contact with fungal spores wounds (even small) of plant tissue or by merging the roots (very close to plants), resulting in increasingly lethal and not treatable with standard antifungal products. The acute form causes the complete desiccation of parts of the foliage and can be present on the logs in the form of large necrotic areas often presenting unusual pigmentations. The common name of the disease, "canker stain of plane tree", comes from the characteristic reddish color that transmits the parasite to areas woody affected. In Italy, where the disease appeared for the first time in the '70s and spread quickly across large areas both north and south (Lombardy is currently the worst affected region), is in effect an obligation to fight against disease, including strict rules on the slaughter of infected individuals and disposal of timber struck.
