Dippel Scotch broom: The success of Scotch broom is due to 1) its wide tolerance of soil conditions; 2) its ability to fix nitrogen and grow for most of the year given adequate precipitation and a mild climate and 3) its abundant production of long lasting viable seeds. Most herbicides so applied are non selective and will kill most, if not all, of the vegetation sprayed. Station Bulletin.

The El Dorado County government is managing broom throughout the county. 3) Basal/Stem sprays: This technique involves the use of backpack sprayers in applying high concentrations of herbicides in oil or other penetrating carriers to the basal portion of stems to be killed. 23 Pamaron Way Contact: Bruce Bingham Wheeler, C.T., D.A. After flowering, Scotch broom produces long, flattened seed pods which mature in late summer or fall. Although there are high populations of the weevil in the coastal mountains, only small populations survive on Sierran plants. In the West, Scotch broom has now become established along the inland valleys of the Pacific Northwest, from British Columbia to central California (Hitchcock and Cronquist 1973). The object of hoeing is to cut off weeds without going too deeply into the ground and doing damage to the roots of desirable vegetation. Most of the explosively released seeds fall within 1 m of the parent plant. In Europe it is found on moderately leached soils in heathlands, acidic grasslands and inland dunes (Bicher and Larsen 1958). California Dept.

A similar earlier proposal had run into strong objections from nursery men and landscapers (Kosesan 1978). Both the moth and the seed weevil are specific to Cytisus scoparius and will notfeed or develop on French broom (Cytisus monspessulanus), Spanish broom (Spartium junceum) or gorse (Ulex europaeus) (Andres 1979). This map shows two major concentrations of Scotch broom. USDA. Subsequent rainfall dissolves the pellets and leaches the herbicide down to the root system. Those species that survive the treatment may, after repeated sprayings, form an herbicide resistant vegetation cover, thus creating a more difficult problem to deal with. Releasing chickens into an area after the mature plants are removed allows them to scratch and peck out weed seeds and potentially reduce the weed seed bank in the soil (Andres 1979). Williams (1983) suggested that broom stands provide good environment for the establishment of other broadleaved shrubs or trees. The economics of herbicides in New Zealand plantation practice. Mechanical removal and use of picloram (Tordon®) over the last five years on Angel Island have been ineffective. (in C.G.R. Spot chemical methods consist of various techniques for manually applying herbicides to individual plants or small clumps of plants (such as stump resprouts). 5 1 3. and F.L. (info source: Learn2Grow.com). Sheep are valuable not only for weed control but also for additional income from the sale of their wool and their contribution of fertilizer to the soil. Picloram was sprayed on the broom plants but "flashed back" into surrounding vegetation, creating undesired damage. 1984. Hitchcock, C.L. Success may be somewhat limited because manual techniques do not totally eradicate broom. Ryburn, Marla. The 1982 survey reflected surprise at the lack of French broom mentioned. 2) Cut stump treatment: Herbicides are directly applied to the cambial area around the edges of freshly cut stumps. California Native Plant Society Native: Europe. andreanus(Puiss.) The topographic relief in Mt. Cytisus scoparius (L.) Link Genista scoparia (L.) Lam. The pods turn black when mature and release 3-7 seeds explosively. 1985. Mechanical means are avoided as they are believed to disturb the soil and create an excellent seed bed for broom seedlings (Delfino 1985). Vice President, ESA Madrone. Weed Control Forestry, Nottingham. Each pod usually contains 5-8 seeds (Waloff and Richards 1977). Waloff, N. and O.W. Scotch broom is very drought tolerant and needs a well-drained sandy soil, although heavier soils curtail invasiveness by curbing self-seeding. (2.5-5 cm) long, and will explode when mature forcefully expelling the seeds. Please try again. Seed pods are fuzzy on the edges, 1-2 in. The seeds and seedlings may establish sufficiently to eventually shade out the broom (Williams 1983). Sheep are more selective than goats in their food choices but function well in grazing down a variety of plants. It is known for its profusion of large, fragrant pea flowers and named for its numerous, bright green, upright-arching branches and stems that resemble sweeping brooms. Unpublished manuscript. Despite damage to as much as 60% of the seed at some sites, the weevil has only limited impact on controlling Scotch broom. Ann. Broadcast herbicide application may be most effective where the weed infestation is very dense and needs to be killed and dessicated prior to burning. These methods are highly selective as only specific plants are treated. maritimus is found on exposed sea cliffs, unlike Cytisus scoparius ssp. By 1930 the citizens of El Dorado County had become so concerned by Scotch broom infestation that they had an uninfested part of the county declared a Weed Free Area (Mobley 1954). Tips are soon replaced by growth from lateral buds (Williams 1981). These methods are highly selective and permit weeds to be removed without damage to surrounding native vegetation. 1970. 1985. Both types of treatments have advantages and disadvantages and will be discussed separately. The Oregon Department of Agriculture politely declined, as broom is looked upon as a "desirable ornamental." Burning is best followed by, 2) subsequent burning to exhaust soil seed bank and underground food reserves, and/or. The overall effect is rather subtle, making it difficult to measure the full impact of the insect on the weed. Illustrated Flora of the Pacific States. Res. The mostly glabrous banner is ovate to rounded; wings are oblong or ovate; and the keel may be straight or curved. Millener, L.H. Calif. 51(4):184 186.

Sheepfarming Annual (Massey Agric. Fremontia 6(4):11-15. Please notify the California Field Office of The Nature Conservancy of any field observations in which a native insect or pathogen is seen to have detrimental effects on broom. Proc. The physical control methods discussed below, manual and mechanical, produce slash (i.e. Tamarind Isolated Ripe. Scotch broom grows to 1-3 metres in height at maturity. These methods are often non selective in that all vegetation on a treated site is affected. 1933. The viability of seeds. This is quite easy as they are like peas. It prevents reforestation, creates a high fire hazard, renders rangeland worthless and greatly increases the cost of maintenance of roads, ditches, canals, power and telephone lines...Even wildlife suffers...as the growth becomes too dense for quail to thrive and there is no forage left for deer...They must move to new ranges or starve. If it is true that broom is shade intolerant and can be displaced by taller growing species, why has broom spread so quickly throughout California? In later seral stages in New Zealand, shrubs with photosynthetic tissue mostly on the outer crown readily shade out broom. BIOLOGICAL CONTROL OF WEEDS: A WORLD CATALOGUE OF AGENTS AND THEIR TARGET WEEDS. Broom spreads solely by seed. It is hardy to zone (UK) 5 and is not frost tender. These include soaking the seeds in hot water and mechanical scarification (piercing, chipping or filing the seed coat) followed by a three hour soak in water. The most commonly mentioned herbicides for broom are 2,4-D, alone or with additives. Mulligan, B.O. At 68 degrees Fahrenheit, seeds generally germinate in 4 weeks. Green (1976) reported successful control of large broom clumps with hand applied granules of picloram. This is an important step before many other methods are tried, as it removes the above ground portion of the plant. 1985. Proc.

Broom has been used for thatching, fence rows and cattle fodder. Broom pods often open explosively, especially in a drying wind, and the seeds may be widely scattered (McClintock 1985). Burning may contribute to a minimum, as it provides bare soil which is important order.
