Abstract: 

ROOT – KNOT NEMATODES, MELOIDOGYNE SPP. ARE AMONG THE MOST SERIOUS PESTS OF AGRICULTURAL CROPS. IN THIS RESEARCH EXTENSIVE SURVEY WAS CARRIED OUT TO COLLECT AND IDENTIFY WEED HOSTS OF ROOT KNOT NEMATODE IN KHORASAN RAZAVI PROVINCE DURING 2005 -2007.WEED SEEDS WERE PLANTED IN CLAY POTS CONTAINING 250 ML. NEMATODE INFESTED SOILS (20 J2/GR-SOIL) AND HELD IN A GROWTH CHAMBER AT 25-27 OC AND 16 HOURS LIGHT OF 45 DAYS. THE WEED THAT THE PATHOGEN WAS ABLE TO INFECT AND REPRODUCE WAS KNOWN AS ITS HOSTS. ACCORDING TO THIS STUDY 31 WEED SPECIES BELONGING TO 14 PLANT FAMILIES WERE NAMED FOR ROOT KONT NEMATODES.IT WAS CONCLUDED THAT ELIMINATION OF WEED HOSTS IN COMBINATION WITH CROP ROTATION USING NON-HOT PLANTS ARE IMPORTANT FACTORS IN EFFECTIVE INTEGRATED NEMATODE MANAGEMENT PROGRAMME.
