Most craft broom makers procure broom corn from local growers or buy it from companies who specialize in craft broom materials and tools. I purchase ten pound boxes of craft broom corn (broom corn with a section of stalk for weaving) from Caddy Supply Company of . See: Rhododendron-Rusts. Cause Chrysomyxa sp., a fungus. Species reported from the Northwest include C. arctostaphyli (spruce broom rust, with kinnikinnick as the other host); C. ledicola (with labrador-tea, Ledum sp., as the other host); C. piperiana (with Rhododendron macrophyllum as the other host); and C. weirii, which does not need an alternate teliospores germinate in spring and.
Rust or witches broom on spruce trees. Asked Aug , PM EDT. Hi my neighbour half mile away either had rust fungi or witches broom or both. The trees have been cut down, delimbed and taken to compose. I was planning to haul the trees to my place and cut/split up for firewood. stages. Spruce budworm are a major driver of ecosystem dynamics, and their outbreaks have profound effects on forest composition and structure over very large areas (Blais , Bergeron et al. , Candau and Fleming , MacLean and Andersen ). For example, 41 million ha of Ontario forest have been defoliated by spruce.
"Broom reminds us of the importance of caring for our own personal well-being on all levels - physical, mental, emotional, and spiritual. Falling at the end of the Celtic year, the month of broom is a time for taking stock, for making a clean sweep, for ridding yourself of unnecessary baggage and harmful habits. Spruce needle rust, also known as Weir's cushion rust, is caused by the fungus Chrysomyxa weirii. Hosts Most spruce (Picea) species are susceptible to the disease but Colorado blue spruce (P. pungens) is particularly susceptible. Other common hosts include white spruce (P. glauca), black spruce (P. mariana), red spruce (P. rubens) and Sitka spruce (P. sitchensis).

Figure Topkill caused by spruce broom rust. Figure Kinnikinnick is the alternate host to spruce broom rust.
Figure Foliage yellows in late summer. Figure Chickweeds. Spruce broom rust (Chrysomyxa arctostaphyli) occurs only in N. America, and reduces growth of infected trees by c.
30% in 10 yr. The mortality rate of infected trees was X3 that of healthy. No outbreaks of fir [Abies] broom rust (Melampsorella caryophyllacearum) older than 26 yr. were found so less is known about the damage caused by this by: 3.
Spruce Broom Rust. Chrysomyxa arctostaphyli Dietel. Basidiomycotina, Uredinales, Coleosporiaceae. Hosts: In B.C. the aecial hosts of Chrysomyxa arctostaphyli are white, black, Norway, Engelmann, and Sitka spruce. Elsewhere it is reported on blue and red spruce. Fir Broom Rust. Melampsorella caryophyllacearum Schroet.
(=Melampsorella ceratsii (Pers.) Schroet.) Basidiomycotina, Uredinales, Pucciniastraceae. Hosts: In B.C., the aecial hosts of Melampsorella caryophyllacearum are amabilis fir, grand fir, and subalpine fir.
Elsewhere in North America is is also found on balsam, noble, California red, Pacific sliver, and white firs. If the witches' broom is caused by a genetic mutation, there will likely only be one cluster of twigs in the tree.
Conifer trees, such as pine, fir, spruce and juniper, might be affected by a genetic mutation that causes witches' : Vanessa Richins Myers. Leaf Rusts of Hardwoods and Needle Rusts of ConifersJuniper Broom Rust - Gymnosporangium nidus-avis Juniper with witches' telia form firectly on the needles.
This photo shows the telia (dark areas) when on branches from a juniper broom during wet weather. The telia have expanded producing a gelatinous mass which contains the eberry, Amelanchier, is the.
Fir broom rust is rarely fatal, but it can result in growth reduction. The fungus lives on two hosts: the primary host is balsam fir and the secondary host is chickweed.
A first type of spores is produced in spring on the two faces of needles contained in the broom. on spruce and fir varied widely among the sites sampled. Several of the sites sampled did not have either spruce or fir broom rust. Spruce broom rust was most common on the Gunnison, San Juan, and Rio Grande National Forests.
The East Florida site on the Pine Ranger District (San Juan National Forest) had the greatest per. Spruce brooms are often associated with stem deformations, reduced increment growth, broken tops, and tree mortality. Rust brooms also serve as infection courts for decay fungi such as Phellinus pini contributing to increased levels of damage.

Severe Fir Broom Rust can cause losses for growers. The fall and the upcoming sale season, are a good times to see if it is present in the field. When taking off the bottom limbs of trees be sure to take notice if any brooms are present. Cause The fungus Melampsorella caryophyllacearum causes large brooms on true firs (Abies sp) including A.
concolor (white fir), A. magnifica (Calif. Red fir) A. amabilis (Cascade fir), A. balsamea (balsam fir), A. grandis (grand fir), and A. lasiocarpa (alpine fir). The disease is found throughout the Pacific Northwest. The main problem is growth loss rather than poor wood quality.
Diagnostics: Red spruce is dominant, and fir is usually present but much less ration is dense in patches, and herbaceous species are almost absent.

A witch's broom is an unusually dense and compact cluster of twigs and foliage formed on a woody plant. The mass of shoots comes from a common point, giving the growth a broom-like appearance.
The witch's broom may last several years. term effects on spruce-fir forests. The immediate effects include changes in stand structure and composition. The longer-term effects come from successional changes that result from microclimate changes as well.

Brown to orange hornlike or cushionlike projections (telia) are produced in the spring; these swell and gelatinize during wet periods and are quite spectacular.Witch's broom or witches' broom is a deformity in a woody plant, typically a tree, where the natural structure of the plant is changed.A dense mass of shoots grows from a single point, with the resulting structure resembling a broom or a bird's is sometimes caused by pathogens.
Witch-broom disease, caused by phytoplasmas or basidiomycetes, is economically important in a number of crop.
