General Information

RENSEIGNEMENTS GÉNÉRAUX

Ball mustard is most abundant in the prairie provinces. It is present in relatively low frequencies in most crops but spreads as a seed contaminant; seed pods are difficult to separate from crops like canola and mustard. Occasional specimens may have four-sided or sharp-pointed pods (Francis and Warwick 2003).

Similar Species

ESPÈCES SEMBLABLES

Similar species are based on a study of seed morphology of various species, and those with similar dispersal units are identified. The study is limited by physical specimen and literature availability at the time of examination, and possibly impacted by the subjectivity of the authors based on their knowledge and experience. Providing similar species information for seed identification is to make users aware of similarities that could possibly result in misidentification.

Calepina irregularis (white ball mustard)

Calepina irregularis pods are a similar single-seeded, brown colour, reticulated surface as ball mustard pods. The seed is also orange-coloured, oily and fragile.

Calepina irregularis pods are teardrop- shaped with an obvious style appendage and generally larger (average length: 2.8 mm; average width: 1.7 mm); the surface reticulations have wider interspaces.
