Due to commonalities in symptoms of P. juniperova and related Phomopsis blights, diagnosis can often be difficult. Although the observation of symptoms is the first step in identification of this pathogen, the presence of both alpha and beta spores in the pycnidium must be verified in order to confirm the existence of P. juniperova.
Like many rusts, G. sabinae requires two different hosts to complete its life cycle from year to year. Juniper is the winter host and pear is the summer host. Spores (called aeciospores) are produced from the fungal lantern-shaped growths which protrude from the blisters on the underside of the pear leaf which become airborne and infect junipers.
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.

However, leaf spots may, in advanced stages, expand to kill entire areas of leaf tissue and thus exhibit blight symptoms. Blights are often named after their causative agent. For example, Colletotrichum blight is named after the fungus Colletotrichum capsici, and Phytophthora blight is named after the water mold Phytophthora parasitica. [11]
Juniperus ashei (Ashe juniper, mountain cedar, blueberry juniper, post cedar, or just cedar) is a drought-tolerant evergreen tree, native from northeastern Mexico and the south-central United States to southern Missouri. The largest areas are in central Texas, where extensive stands occur.
Some junipers are susceptible to Gymnosporangium rust disease and can be a serious problem for those people growing apple trees, an alternate host of the disease. Juniper is the exclusive food plant of the larvae of some moths and butterflies, including Bucculatrix inusitata, juniper carpet, Chionodes electella, Chionodes viduella, juniper pug ...
Juniperus scopulorum is a small evergreen tree that in favorable conditions may reach as much as 20 metres (66 feet) in height. [4] However, on sites with little water or intense sun it will only attain shrub height, and even those that reach tree size will more typically be 4.6–6.1 metres (15–20 feet) tall in open juniper woodlands.
