|Scientific Name||Phalaris paradoxa|
|Common Names||English: Hooded canarygrass; German: Seltsames Glanzgras; French: Alpiste paradoxal; Spanish: Alpiste|
Glumes with marked teeth, panicle 4-5 cm (1.57 - 1.97 inch) long, 1-1.5 cm (0.39 - 0.59 inch) wide.
Plant tufted, leaves with a flat blade, youngest leaf rolled, abundant tillering with numerous forks arising from nodes.
30-120 cm (11.81 - 47.24 inch) high, stem spreading then ascending.
Membranous and truncate ligule.
Upper leaves have a swollen leaf-sheath which envelopes the inflorescence before flowering.
Inflorescence spike -like, narrowed at both ends; usually and partly enclosed in the leaf sheath.
Seeds 6-7 in flattened spikelet.
Caryopsis, 2.5 mm (0.098 inch) long.
Germination in autumn and winter.
Viability of Seeds
Short lived in soil seed bank.
Persistent seed bank, emergence from shallow depths (< 3 cm, 1.18 inch).
P. paradoxa is an aggressive annual grass weed of many crops in moderate and warm areas (Mediterranean basin, Asia, Australia, Mexico, Southern States of the USA, Southern Europe, East Europe).
Hooded canarygrass prefers alluvial, sandy-clay or clay texture soils with high soil moisture.
Additional Crop Information
Cereals (spring and winter).
P. paradoxa is frequency increasing in crops.
Useful non-chemical contribution to Integrated Weed Management
Crop competition and high seeding density of crop may reduce P. paradoxa development.
