During a weed survey conducted in 86 wheat fields of 16 provinces in 1982-83, a total number of 103 weed species were found. The 10 most important weeds (or groups of weeds) were: 1) Avena spp. (A.sterilis, A. fatua), 2) Lolium spp. (L. multiflorum, L. rigidum, L. temulentum), 3) Galium spp. (G. spurium, G. tricornutum, G. aparine), 4) Alopecurus spp. (A. myosuroides, A. rendlei), 5) Papaver spp. (P.rhoeas, P. agremone), 6) Phalaris spp. (P. brachystachys, P. paradoxa, P. minor), 7) Polygonum spp. (P. aviculare, P. lapathifolium), 8) Bromus spp. (B. sterilis, B. tectorum, B. japonicus, B. arvensis, B. hordeaceus), 9) Marticaria chamomilla and 10) Anthemis spp. Avena fatua was found only in one field in Northern Greece and appears to be very rare. Lolium multiflorum was restricted only in Peloponnese and Thessalia, while L. rigidum was found in all areas. Bifora radians, a new weed for Greece, was widespread throughout the country, although in low densities in southern provinces. Phalaris spp. were much more frequent than Bromus spp. in central Greece, while in Macedonia Bromus spp. much more frequent than Phalaris spp.
