Abstract

Root ROT and CROWN ROT of RICE is one of the important RICE diseases in Gilan and Zanjan provinces. During 1999 - 2002 different regions of RICE grown in two provinces were surveyed. Infected plants and soils around the ROOTs have been collected from studied areas. ROOTs and CROWNs of infected plants were cultured on PDA, PPA and CLA media after surface sterilization with 05% sodium hypochlorite. Collected soils suspensions were provided in water agar liquid to isolate casual agent from soils around the ROOTs. The casual agent of disease was recognized as FUSARIUM moniliforme which isolated from CROWN and ROOT of infected plants and soils. The color of colonies on PDA medium initially was white and then became violet to grey. Microconidia were chain and macroconidia were cylindrical and long with 3-5 septa. The disease was severing in some areas especially in Zanjan province around the Ghezel Oezan River which had shown 70% to 80% infection in some places. There was not any ROTation between RICE cultivation in this area and just conventional types such as Champa or Gerdeh have been cultured. Eight new cultivars of RICE were cultured in natural infected farm to select relatively resistant to disease. However Binam was the best cultivar had shown resistance to disease and yield production. Most area in Zanjan province were used sowing seeds rather than using seedling which infected plants can be eliminated.
