Management Notes (for the Swan NRM Region)

Alternative Names. Jointed Charlock, Mediterranean Radish, Sea Radish.

General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Wind, water, machinery. Toxicity. Poisonous in large quantities to mammals. Seedbank persistence. 20 years.

Notes. Can be biennial. Weed of highly disturbed edges. Germinates after significant autumn rains, otherwise germination can be sporadic and staggered throughout the year. Has a flexible lifecycle, high genotypic and phenotypic variablity, enabling it to adapt to different environments. Produces prolific seed with high longevity and dormancy. Has recorded resistance to chlorsulfuron in South Africa and multiple resistance to several herbicide groups in other regions.

Additional information. History of use/introduction. Macaronesia, northern Africa, temperate Asia, Europe.

Suggested method of management and control. Hand remove isolated plants several times throughout the year. Spot spray 1% glyphosate before flowering. A combination of approaches is usually most successful. Read the manufacturers' labels and material safety data sheets before using herbicides. For further information consult the Australian Pesticides and Veterinary Medicines Authority to determine the status of permits for your situation or state.
