General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Contaminated seed, soil movement, water run-off. Seedbank persistence. 20 years.
Notes. Colonises degraded sites. Can germinate throughout the year, with the main flush in autumn and spring. Any soil disturbance can cause mass emergence of seedlings. Seed has an oil sack that attracts ants. May hybridise with Fumaria capreolata. Can be difficult to manage due to a persistent soil seedbank. Herbicide control can be unpredicatable and variable, with tolerance and resistance varying among species of Fumaria.
Additional information. Origin. Europe, north Africa. Similar exotic species. Fumaria capreolata.
Suggested method of management and control. Easily hand removed however this needs to be repeated at least every 10 weeks during the growing season. Continual germination and seedlings emerging after the disturbance of hand removal requires consistent follow-up. Spray metsulfuron methyl 0.1 g/15 L (2.5 g/ha) + wetting agent or try glyphosate at 0.5%. 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.
