Gymnosporangium juniperi-virginianae is a plant pathogen that causes cedar-apple rust. [1] In virtually any location where apples or crabapples and eastern red cedar (Juniperus virginiana) coexist, cedar apple rust can be a destructive or disfiguring disease on both the apples and cedars.
Juniperus virginiana foliage and mature cones. Juniperus virginiana is a dense slow-growing coniferous evergreen tree with a conical or subcylindrical shaped crown [8] that may never become more than a bush on poor soil, but is ordinarily from 5–20 metres (16–66 feet) tall, with a short trunk 30–100 centimetres (12–39 inches) in diameter, rarely to 27 m (89 ft) in height and 170 cm (67 ...
Phomopsis blight of juniper is a foliar disease discovered in 1917 [1] caused by the fungal pathogen Phomopsis juniperovora.The fungus infects new growth of juniper trees or shrubs, i.e. the seedlings or young shoots of mature trees.
Gymnosporangium globosum is a heteroecious rust fungus that requires two hosts to complete its life cycle. Its telial stage occurs on eastern red cedar, Rocky Mountain juniper, southern red cedar, and other common junipers while its aecial stage will be found on apple, crabapple, hawthorne, and occasionally on pear, quince, and serviceberry.
Stands that produce enough wood for specialty uses generally go under the common name "cedar", [27] including Juniperus virginiana, the "red cedar" that is used widely in cedar drawers and closets. [28] The lack of space or a hyphen between the words "red" and "cedar" is sometimes used to indicate that this species is not a true cedar . [29]
Amid mounting fears over the potentially deadly diseases the creatures can spread, one mother is raising concerns about a type of tick so small most people wouldn't be able to spot it on their own ...
The complete picture of long-term ecological effects from invasive pests is difficult to measure; and it is too early to determine the effects of the many new invasive pest introductions. Much of the research has focused of the biology of the pests—i.e. life cycle and host preferences—towards understanding how to contain their spread. [10]
