The sheath rot fungus (Sarocladium oryzae) of rice was isolated from seedlings, sheaths and browned unhulled rice of infected plants. The fungus was also isolated from rice stubble in infested fields, unhulled rice and hull that all remained in an open field until the following spring (early summer), but not from grass seeds or barley plants. These results indicate that S. oryzae is seedborne, and survives in unhulled rice, rice hull, and stubble in fields in winter.
