The alfalfa stem nematode Ditylenchus dipsaci (Kühn 1857) Filipjev 1936 as an important threat for cultivation of alfalfa in Iran
AbstractAlfalfa (Medicago sativa L.) is a very important source of food for livestock which provides the main source of meat production in Iran. Although the need for yield increase has encouraged some farmers to apply scientific methods of crop production including pest control programs, the nematode problems of this crop have not been investigated in Iran. However, nematode damage, especially that of Ditylenchus dipsaci (Kuhn) Filipjev, to alfalfa and clover has been known for some time in America and Europe (Amos 1919, Goodey 1922, Ware 1925, Goodey 1933, Christie 1959, Southey 1959, Anon. 1961, Bingefors 1961, Thorne 1961, McClohon and Minton 1963, Godeck and Favret 1965, Sherwood et al. 1967, Bingefors and Eriksson 1968, Griffin 1968, Tseng et al. 1968, Wynne and Busbice 1968).
