Résumé
We examined the weed seeds present in crop grain samples from 2013 from across 200 cereal fields in Huelva and Seville provinces, Andalusia, South-western Spain. Ninety-one weed species were identified of which 29 species were present in at least 5% of samples. “Lolium rigidum” was the most frequent (74%) and abundant species. The weedy species of the genus “Phalaris” were also highly frequent (66-32%). “Polygonum aviculare”, “Convolvulus arvensis”, “Chrysanthemum coronarium”, “Pulicaria paludosa” and “Centaurea diluta” were detected in more than 20% of samples. Compared to available data for the whole cereal crop area in Spain, we found a similar frequency of the dominant weeds “L. rigidum” and “P. aviculare” but a much higher presence of “Phalaris” spp. In an opposite trend, the frequency of specialist segetal species was much lower.
