Abstract:
Cereal cyst nematodes are one of the most important damaging nematodes of wheat and barley in the world. Heterodera filipjevi is widely distributed on wheat in Iran. In this study, an experiment was conducted with four wheat cultivars (Cvs. Chamran,Virinak,Yavarus and Behrang), barley (Cv. Zehak) and triticale (Cv. Janilo) in a randomized complete block design with 6 treatments (1 plot not sprayed and 1 plot sprayed with a nematicide as control) and four replications in a nematode infested wheat field in Ramshir region of Khuzestan province during growing season 2008-2009. The results indicated that usage of nematicide reduced grain yield, shoot dry weight, shoot height and tillering by 31-73, 6-47, 1- 21 and 11-40 percent respectively as was compared to control. H. filipjevi was multiplied on the all plants in the test, but durum wheat cultivars were better than bread wheat cultivars to the nematode.
