Ulmus Americana 'Augustine'
The American elm cultivar ''Ulmus americana'' 'Augustine', originally called 'Augustine Ascending', was cloned by Archie M. Augustine of the Augustine Nursery of Bloomington, Illinois, from a nursery seedling planted in 1927 in Normal, Illinois, and found to be columnar in habit. See also the similar cultivars 'Columnaris' and 'Ascendens'. It is not known why such a promising clone as 'Ascendens' appears rare in cultivation, but 'Augustine Ascending' was released at about the same date. Neither Green nor Santamour suggested that they were synonyms. Description 'Augustine' is a vigorous fastigiate tree distinguished by its thicker branches and larger, more deeply toothed leaves. ''Flower and Garden Magazine'' reported that the original tree was still standing in 1959 and – erroneously – that the cultivar did not produce seed. The deep root-system of the cultivar was said to be less likely to damage sidewalks than American elm generally. Pests and diseases 'Augustine' ha ...

Elm Yellows
Elm yellows is a plant disease of elm trees that is spread by leafhoppers or by root grafts."Elm Yellows." Elmcare.Com. 19 Mar. 2008 . Elm yellows, also known as elm phloem necrosis, is very aggressive, with no known cure. Elm yellows occurs in the eastern United States, and southern Ontario in Canada. It is caused by phytoplasmas which infect the phloem (inner bark) of the tree.Price, Terry. "Wilt Diseases." Forestpests.Org. 23 Mar. 2005. 19 Mar. 2008 . Similar phytoplasmas, also known confusingly as 'Elm yellows', also occur in Europe.Conti, M., D'Agostino, G., Mittembergher, L. (1987) A recent epiphytotic of elm yellows in Italy.

Verticillium Wilt
Verticillium wilt is a wilt disease affecting over 350 species of eudicot plants. It is caused by six species of ''Verticillium'' fungi: ''V. dahliae'', ''V. albo-atrum'', ''V. longisporum'', ''V. nubilum'', ''V. theobromae'' and ''V. tricorpus''. Many economically important plants are susceptible including cotton, tomatoes, potatoes, oilseed rape, eggplants, peppers and ornamentals, as well as others in natural vegetation communities. Many eudicot species and cultivars are resistant to the disease and all monocots, gymnosperms and ferns are immune. Signs are superficially similar to ''Fusarium'' wilts. There are no fungicides characterized for the control of this disease but soil fumigation with chloropicrin has been proven successful in dramatically reducing ''Verticillium'' wilt in diverse crops such as vegetables using plasticulture production methods, and in non-tarped potato production in North America . Additional strategies to manage the disease include crop rotation, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Popillia Japonica
The Japanese beetle (''Popillia japonica'') is a species of scarab beetle. The adult measures in length and in width, has iridescent copper-colored elytra and a green thorax and head. It is not very destructive in Japan (where it is controlled by natural predators), but in North America and some regions of Europe is a noted pest to roughly 300 species of plants, including rose bushes, grapes, hops, canna, crape myrtles, birch trees, linden trees, and others. The adult beetles damage plants by skeletonizing the foliage (i.e., consuming only the material between a leaf's veins) as well as, at times, feeding on a plant's fruit. The subterranean larvae feed on the roots of grasses. Description Adult ''P. japonica'' measure in length and in width, with iridescent copper-colored elytra and green thorax and head. A row of white tufts (spots) of hair project from under the wing covers on each side of the body. Distribution ''Popillia japonica'' is native to Japan, but ...

Dutch Elm Disease
Dutch elm disease (DED) is caused by a member of the sac fungi (Ascomycota) affecting elm trees, and is spread by elm bark beetles. Although believed to be originally native to Asia, the disease was accidentally introduced into Americas, America, Europe, and New Zealand. In these regions it has devastated native populations of elms that did not have resistance to the disease. The name "Dutch elm disease" refers to its identification in 1921 and later in the Netherlands by Dutch phytopathologists Marie Beatrice Schol-Schwarz, Bea Schwarz and Christine Buisman, who both worked with professor Johanna Westerdijk. The disease affects species in the genera ''Ulmus'' and ''Zelkova''; therefore it is not specific to the Ulmus × hollandica, Dutch elm hybrid. Overview Dutch elm disease (DED) is caused by ascomycete microfungi. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
