Management Notes (for the Swan NRM Region)

Alternative Names. Slender Dock, Brown's Dock, Hooked Dock.

General Biology. Growth form. Herb. Life form. Perennial. Reproduction. Seed, root fragments. Dispersal. Animals, clothing (by adhesion), soil, machinery, seed contaminant. Toxicity. Posionous to mammals. Seedbank persistence. 80+ years (some species). Fire response. Resprouts after fire.

Notes. Coloniser of disturbed sites that prefers open habitats in full sun. Has vigourous growth and, once established, competes with other plant species for light, moisture and plant nutrients. Produces prolific amount of seed that germinate at any time during the growing season, however germination is inhibited while the seed remains enclosed in the fruit capsule. Germinates in autumn, and seed matures through summer. Fruits have hooked teeth that are dispersed by adhesion. Frequently forms sterile hybrids capable of vegetative spread. Mature plants have a deep root system which aids survival over summer and plants quickly regenerate with the onset of autumn rain. Rapid growth early in the season gives a competitive advantage over other germinating annuals.

Additional information. Origin. Eastern Australia. Similar native species. Rumex dumosus, R. drummondii.

Suggested method of management and control. Hand remove small/isolated infestations of seedlings and young rosettes. If removing older plants ensure entire plant, including the root, can be removed, otherwise spread will occur from root fragments. Alternatively spot spray with 1% glyphosate + surfactant in early bud stage. Use a higher rate on well established plants. 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.
