Olive Quick Decline Syndrome
Olive quick decline syndrome (OQDS) (in Italian: ''Complesso da Disseccamento Rapido dell'Olivo'', CDRO or CoDiRo) is a wasting disease of olive trees which causes wikt:dieback, dieback of the leaves, twigs and branches so that the trees no longer produce crops of olives. The main cause is a strain of the bacterium, ''Xylella fastidiosa'', which is spread by plant-sucking insects such as the meadow froghopper. The bacteria restrict the flow of sap within the tree and so choke its extremities. __TOC__ Impact The disease particularly affects olive groves in Southern Italy. It was first detected in Italy in 2013, in the Salento, Salento Peninsula; by late 2013, it was estimated that approximately 8,000 hectares were affected. As of 2020, the disease was threatening olive groves and oil production in Italy, Greece, and Spain, which together account for 95% of European oil production. One 2020 model predicts a potential economic impact of the disease for Italy over 50 years betwee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Olive Tree
The olive, botanical name ''Olea europaea'', meaning 'European olive' in Latin, is a species of small tree or shrub in the family Oleaceae, found traditionally in the Mediterranean Basin. When in shrub form, it is known as ''Olea europaea'' 'Montra', dwarf olive, or little olive. The species is cultivated in all the countries of the Mediterranean, as well as in Australia, New Zealand, North and South America and South Africa. ''Olea europaea'' is the type species for the genus ''Olea''. The olive's fruit, also called an "olive", is of major agricultural importance in the Mediterranean region as the source of olive oil; it is one of the core ingredients in Mediterranean cuisine. The tree and its fruit give their name to the plant family, which also includes species such as lilac, jasmine, forsythia, and the true ash tree. Thousands of cultivars of the olive tree are known. Olive cultivars may be used primarily for oil, eating, or both. Olives cultivated for consumption are gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dieback
Dieback may refer to a number of plant problems and diseases including: * Forest dieback caused by acid rain, heavy metal pollution, or imported pathogens * The death of regions of a plant or similar organism caused by physical damage, such as from pruning * Those caused by the genus '' Eutypa'', such as ''Eutypa'' dieback * Those caused by the genus ''Phytophthora'', such as ''Phytophthora cinnamomi'' dieback * Those caused by the genus ''Seiridium'', such as ''Seiridium cardinale'' dieback or cypress canker * Birch dieback, caused by several pathogens * Ash dieback, caused by ''Hymenoscyphus fraxineus ''Hymenoscyphus fraxineus'' () is an ascomycete fungus that causes ash dieback, a chronic fungal disease of ash trees in Europe characterised by leaf loss and crown dieback in infected trees.

Xylella Fastidiosa
''Xylella fastidiosa'' is an aerobic, Gram-negative bacterium, Gram-negative bacterium of the genus ''Xylella''. It is a plant pathogen, that grows in the water transport tissues of plants (Xylem, xylem vessels) and is transmitted exclusively by xylem sap-feeding insects such as Sharpshooter (insect), sharpshooters and Aphrophoridae, spittlebugs. Many plant diseases are due to infections of ''X. fastidiosa'', including bacterial leaf scorch, oleander leaf scorch, coffee leaf scorch (CLS), alfalfa dwarf, phony peach disease, and the economically important Pierce's disease of grapes (PD), olive quick decline syndrome (OQDS), and citrus variegated chlorosis (CVC). While the largest outbreaks of ''X. fastidiosa''–related diseases have occurred in the Americas and Europe, this pathogen has also been found in Taiwan, Israel, and a few other countries worldwide. ''Xylella fastidiosa'' can infect an extremely wide range of plants, many of which do not show any symptoms of disease. Dise ...

Meadow Froghopper
''Philaenus spumarius'', the meadow froghopper or meadow spittlebug, is a species of insect belonging to the spittlebug family Aphrophoridae. In Italy and America, it is economically important as one of the vectors of Pierce's Disease (''Xylella fastidiosa''). Etymology The genus name ''Philaenus'' comes from the Greek ''philein'' ("love"), while the species name ''spumarius'' is from the Latin ''spuma'' ("sparkling"), referring to the foam nests; the binomial ''Philaenus spumarius'' can be translated as "foam lover." Varietas Varietas within this species include: *''Philaenus spumarius var. populellus'' *''Philaenus spumarius var. vittatus'' *''Philaenus spumarius var. lateralis'' *''Philaenus spumarius var. fasciatus'' *''Philaenus spumarius var. gibbus'' Distribution ''Philaenus spumarius'' is quite common and widespread. The species' original distribution was restricted to the Palearctic realm. They are present in most of Europe, in North Africa, in part of Russia, in A ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern Italy
Southern Italy ( it, Sud Italia or ) also known as ''Meridione'' or ''Mezzogiorno'' (), is a macroregion of the Italian Republic consisting of its southern half. The term ''Mezzogiorno'' today refers to regions that are associated with the people, lands or culture of the historical and cultural region that was once politically under the administration of the former Kingdoms of Naples and Sicily (officially denominated as one entity ''Regnum Siciliae citra Pharum'' and ''ultra Pharum'', i.e. "Kingdom of Sicily on the other side of the Strait" and "across the Strait") and which later shared a common organization into Italy's largest pre-unitarian state, the Kingdom of the Two Sicilies. The island of Sardinia, which had neither been part of said region nor of the aforementioned polity and had been under the rule of the Alpine House of Savoy that would eventually annex the Bourbon-led and Southern Italian Kingdom altogether, is nonetheless often subsumed into the ''Mezzogiorno'' ...

Salento
Salento ( Salentino: ''Salentu'', Salentino Griko: ''Σαλέντο'') is a cultural, historical and geographic region at the southern end of the administrative region of Apulia in Southern Italy. It is a sub-peninsula of the Italian Peninsula, sometimes described as the "heel" of the Italian "boot". It encompasses the entire administrative area of the province of Lecce, a large part of the province of Brindisi and part of that of Taranto. The peninsula is also known as Terra d'Otranto, and in the past Sallentina. In ancient times it was called variously Calabria or Messapia. History Messapia (from Greek ''Μεσσαπία'') was the ancient name of a region of Italy largely corresponding to modern Salento. It was inhabited chiefly by the Messapii in classical times. Pokorny derives the toponym from the reconstructed PIE ''*medhyo-'', "middle" and PIE ''*ap-'', "water" (''Mess-apia'', "amid waters"). Pokorny compares the toponym ''Messapia'' to another ancient Italic toponym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bacterial Leaf Scorch
Bacterial leaf scorch (commonly abbreviated BLS, also called bacterial leaf spot) is a disease state affecting many crops, caused mainly by the xylem-plugging bacterium ''Xylella fastidiosa''. It can be mistaken for ordinary ''leaf scorch'' caused by cultural practices such as over-fertilization. Hosts BLS can be found on a wide variety of hosts, ranging from ornamental trees (elm, maple, oak) and shrubs, to crop species including blueberry and almond. Bacterial spot of peppers and tomatoes Bacterial spot of peppers and tomatoes is caused by the bacteria ''Xanthomonas campestris'' pv. ''vesicatoria''. Bacterial spot of peaches Bacterial spot of peaches is caused by the bacteria ''Xanthomonas campestris'' pv. ''pruni''. Spots may form on the leaves and they can be mistaken for ''peach scab'', which is caused by a fungus. Bacterial spot of pecans Symptoms An irregular browning leaf margin which may or may not be bordered by a pale halo.http://www.usna.usda.gov/Rese ...
