General Biology. Growth form. Herb. Life form. Annual. Reproduction. Seed. Dispersal. Contaminated seed, soil movement. Toxicity. Suspected of poisoning stock. Seedbank persistence. 20 years.
Notes. Colonises degraded sites. May hybridise with Fumaria muralis. Can be difficult to control due to a strongly persistent soil seed bank. Herbicide control can be unpredictable and variable, with tolerance and resistance varying among species of Fumaria. Potential biological control agents were assessed after one species Fumaria densiflora developed populations with herbicide resistance.
Additional information. Origin. Northern Africa, temperate Asia, Europe Macronesia, northern Africa, Temperate and western Asia, Europe. Similar exotic species. Fumaria muralis.
Suggested method of management and control. Spray metsulfuron methyl at 0.1 g/15 L (2.5 g/ha) + wetting agent or glyphosate 0.5%. Read the manufacturers' labels and material safety data sheets before using herbicides.
