Rhagadiolus stellatus is an annual species.

Rhagadiolus stellatus reproduces by seed produced in large numbers.

Rhagadiolus stellatus is a clithochorous species (seeds dispersed at shart distance)

Rhagadiolus stellatus is a C3 species.

Algeria: Rhagadiolus stellatus is a common messicolous species of winter annual crops (winter cereals, fallow fields, catch crops) in the north of the country. Seems indifferent to soil type, although more abundant on clayey marl.
Morocco: Rhagadiolus stellatus is a very common nitrophilous species, thriving on clay soil in pastures, wastelands, rock gardens and open forests on plains and low mountains with adequate rainfall, up to 1700 m altitude.

Local harmfulness

Algeria: Rhagadiolus stellatus is a major weed. Rhagadiolus stellatus is one of the most damaging weeds of field crops, as it can colonize practically any ecological environment (a very frequent species). Moreover, its great adaptation to the agricultural environment and its high seed production give it a very high potential for invading plots (an abundant species whenever it is present).

Local control

Algeria: Rhagadiolus stellatus is controlled in cereal crops with a combination of a false-seeding cultivation method combined with a pre-emergence chemical treatment with 2,4-D, dicamba, pendimethalin, trifluralin, etc. or a post-emergence treatment with glufosinate ammonium, linuron, paraquat, metribuzin, etc.
