Dans l\u2019ensemble, les gramin\u00e9es provoqueraient des pollinoses. Les poaceae forment un groupe qui semble particuli\u00e8rement complexe en raison de la taille de ce groupe pour les allergologues. Echinochloa crus-galli : pollen allergisant?<\/p>\n\n\n\n

Auto\u00e9cologie: neutronitrophile, gr\u00e8ve alluviale, cultures sur sols battants …<\/p>\n\n\n\n

Plante \u00e0 fort potentiel \u00e9conomique n\u00e9gatif (l’agr\u00e9gat Echinochloa crus-galli\/ E. oryzoides\/E. hispidula). Sans doute, la plus redout\u00e9e pour la culture du riz y compris en cultures noy\u00e9es (\u00e0 la fois par son cycle rapide, et par son \u00e9cologie proche de celle de la c\u00e9r\u00e9ale alimentaire).<\/p>\n\n\n\n

En fort peuplement, pourrait absorber jusqu’\u00e0 80% de l’azote du sol (\u00ab\u00a0Experiments have shown that heavy stands of E. crus-galli may remove 60-80 percent of the nitrogen from the soil in a crop area\u00a0\u00bb);<\/p>\n\n\n\n
