Seedling
Cotyledons very narrow, linear, filiform, 15-20 x 0.5 mm, glabrous. Primordial leaves rosette-shaped, divided into 3-5 filiform, pinnate, petiolate, hairless strips. Subsequent leaves become increasingly divided, long-stalked, with a whitish-edged sheath. The hypocotyled axis is fairly short and purplish. The light-green seedling gives off a characteristic fennel odor when crumpled.
Adult plant
Ridolfia segetum is an upright, glaucous annual plant with a fennel-like odor. Stems are slender, round, finely ridged, branching upwards, glabrous, reaching 120 cm in height. Leaves alternate, long-petiolate, very sheathing at the base, reducing to a sheath at the top of the stems. Blade multi-lobed, with very fine mucronate strips at the apex. Umbels with 15-45 fine, subequal rays, no involucre, terminated by multiflorous umbels, no involucellum. Yellow flowers with emarginate petals, folded over the stylopod into a disk. Fruit: 2 oblong achenes, laterally compressed, brownish, almost smooth, 1-2.5 mm long.

Algeria: Ridolfia segetum is a post-vernal messicolous weed, uncommon in annual crops (winter wheat-cultivated fallow) in the north of the country. It prefers the deep, heavy, more or less tirsified soils of the clay-marl hills of the Tell.
Morocco: Ridolfia segetum is a very common weed of crops in cereals, pastures and fallow land on clay-limestone soil, at altitudes of 0 to 1500 m.

Algeria: Ridolfia segetum is controlled in cereal crops using a combination of false-seeding methods combined with pre-emergence herbicide treatment with oxyfluorfen, propyzamide, trifluralin, etc. or post-emergence herbicide treatment with bentazone, tribuzine, etc. This species has become tolerant to pendimethalin.
