Annual bluegrass (POA ANNUA)

It is one of the more common weed types. The annual bluegrass is a summer weed that winters well, and, as the name suggests, is an annual plant. It develops quite strongly throughout the entire growing season, up to several generations in a given year. Reproduction proceeds quickly, thanks to which the plant takes up an ever increasing area. It is seen in all kinds of crops, but more frequently among wide-row plantations (root vegetables and maize). The annual bluegrass may also be seen in ruderal areas, by roads and in permanently cultivated areas.

The annual bluegrass may be the host to powdery mildew of cereals and grasses, a pest common in agriculture. It prefers rich soils of limited humidity, but it is universal in this regard. It is only controlled mechanically with difficulty due to the fast pace of regrowth. Hence, spraying during leaf formation is necessary, as then such a treatment would be most effective.
