Duriny the years of 2002-2004 extensive survey were carried out to collect and identify weed hosts of sugarbeet cyst nematode in sugarbeet fields of Shirvan, Ghouchan,Chenaran, Fariman,Torbat-jam, Sabzevar ,Torbat-heydaryeh cities.In this work, 78 weed species belonging to18 families were identified .Weed seeds were planted in clay pots containig 250 ml.nematode infested soil (10J2 and eggs/gr.) and held in a growth chamber at 25-27 and 16 hours light for 2 months. The experiments showed that 26 weed species belonging to 8 plant families of Amaranthaceae,Asteraceae,Brassicaceae,Caryophillaceae,Chenopodiaceae,polygonaceae, portulacaceae and Solanaceae were hosts of the nematode.
