Bird’s seed grass is an annual or bienal tufted grass that can grow up to 1 m tall with erected stems. The leaves with a linear acuminate blade have a leaf sheath subcoriaceous to pubescent. The inflorescence at the top of a peduncle is a dense oblong panicle. It is found as a major weed of wheat cultures.
This grass reproduces by seeds.
P. minor grows on sandy alluvial soils and tolerate saline soils. It is present in tropical and temperate regions of the world. In Asia, bird’s seed grass grows in the Middle East, Pakistan, Indian subcontinent, Indonesia and Australia.
It is found as major weed not only in wheat cultures but also in gram, lentils and barley crops. Also frequently found in winter vegetable, oilseeds and fodder crops. In Punjab region of Pakistan P. minor is the most notorious and harmful among all winter annual weeds. Due to abundant use of herbicides it is loosing its feet against wheat in some places of Punjab.

In India, post-emergence application of Isoproturon at 1.0 kg/ha, sulfosulfuron at 25 g/ha, fenoxaprop at 100 g/ha, chlodinafop at 60 g/ha, pendimethalin at 1.5 kg/ha.
In Pakistan, following herbicides may be used for its effective control. Stomp 330 E at 3 l/ha, Isoproturon 50 FW at 2 l/ha, Puma S 75 FW at 1.2 l/ha or Topik 15 WP at 250 gm/ha in pre-emergence and early post-emergence, 25 to 30 days after germination of weed.
