Shortpod Mustard (Hirschfeldia incana) is a dicot weed in the Brassicaceae family. > 0°C, dry winters), Continental climate, wet all year (Warm average temp. However, cultivars that escape hybridize readily with wild types. Petals pale yellow, often with dark veins; claw narrow, ca. It prefers well-drained, dry or moist soil (Plants for a Future, 2012). It was first reported in the United States in June of 2008 in the county of Los Angeles, California (Arkelian 2008). Tolerates, or benefits from, cultivation, browsing pressure, mutilation, fire etc, Has propagules that can remain viable for more than one year, Difficult to identify/detect as a commodity contaminant. Due to its maturation early in the phenologic year, it possibly usurps soil water before other native annual plants reach peak development (Brooks, 2004). Introduction.

Germination response of four pasture species to temperature, light, and post-harvest period. H. incana is considered as moderately invasive by the California Invasive Plant Council (DiTommaso et al., 2013) and has been reported as invasive in Hawaii (PIER, 2013).

Cal-IPC Plant Assessment Form. H. incana is probably dispersed by rodents (Brooks, 2004). In Argentina, this species has been reported as an agricultural weed of secondary importance in small grain crops such as canola (oilseed rape) and alfalfa (Marzocca, 1976) and also infests wheat and barley (Heap, 2015). In Argentina, it is associated with railways and rich soils (Marzocca, 1976). Dense infestations occasionally occur in cultivated or otherwise disturbed areas (Cunningham, 2011).

However, in 1990 the Commission accepted the advice of the Grant Animal and Plant Control Board that enforced control was necessary in that area, and recommended that Buchan weed be declared a local pest plant in the District Council of Grant and the City of Mount Gambier only, pending further review. (2013) recommend manually removing this species before seeds develop (particularly during the seeding stage) as an effective population control method. It has been introduced to South Africa, North America, the central Pacific, South America and East Asia. Sulfometuron combined with non-ionic surfactant can be applied to small plants during preemergence or early postemergence (DiTommaso et al., 2013), however, its effectivity is not specified.

Tillage should be done before black mustard has set seed. In the USA, it has been reported to grow in desert areas (Rollins, 1993). A prolific seed producer, it has a tough taproot that makes it difficult to control with tillage. Cornucopia II: A Source Book of Edible Plants.

The presence of muscilage (adhesive substance) on the seed of H. incana facilitates dispersal on vehicles (Brooks, 2004). It has been reported to accumulate heavy metals and possibly interfere with fire regimes. Seed pods are 4/10 to 1 inch long and are supported on short 1/8 to ¼ inch pedicels.

Hirschfeldia incana, commonly known as shortpod mustard, is an early successional annual to perennial herb. (1988): Annual to perennial herb. The Latin epiphet incana means hoary, alluding to the greyish colour of this species’ hairs. H. incana is a tertiary genetic relative of rapeseed (Brassica napus), cabagge/kale (B. oleracea), and black mustard (B. nigra) (FitzJohn et al., 2007), and thus hold some potential as a crop wild relative for future breeding programmes.

Hirschfeldia is named after the German garden theoretician Christian Cay Lorenz Hirschfeld (1742-1792). Shortpod mustard reproduces only by seed, although plants can resprout from the base when damaged. Brooks M, 2004. The former is distinguished from the latter by its distinctly shorter fruit, seeded and often swollen beak, and smaller petals (Flora of North America Editorial Committee, 2015). Wild mustards (and cultivated ones) can harbor pests and diseases that damage closely related crops. Silique (seed pod) glabrous, erect, 6-10 × 1-2 mm; valves 4-6 mm long, 3-veined when immature but veins obscure when mature; beak swollen, 2-4 mm long, (0)-1-(2)-seeded. This species has a somatic chromosome number of 2n = 14 (n = 7) (Siemens, 2011). Hirschfeldia incana (formerly Brassica geniculata) is a species of flowering plant in the mustard family known by many common names, including shortpod mustard, buchanweed, hoary mustard and Mediterranean mustard. incrassata Gomez-Campo, Hirschfeldia incana subsp.

(90-120 cm) tall. https://npgsweb.ars-grin.gov/gringlobal/taxon/taxonomysimple.aspx, USDA-NRCS, 2016. Plants of H. incana often grow alone, rather than in the dense colonies that seem to be the rule for the other mustards. Shortpod mustard, Mediterranean Mustard Brassicaceae (Mustard Family) Mediterranean mustard is an erect, canescent, biennial or perennial growing to some 3' tall. These should be applied shortly after emergence and are more efficient with the addition of ammonium sulfate (DiTommaso et al., 2013). Hirschfeldia incana, commonly known as shortpod mustard, is an early successional annual to perennial herb. Like most websites we use cookies.

The main means of spread of H. incana is as a contaminant of fodder, and sometimes in oilseeds or vegetable seed (South East Natural Resources Management Board, 2009). H. incana can be confused with black mustard (Brassica nigra) because both have fruits appressed to the rachis.
