Abstract
The 'take-all' disease of wheat was first reported in Korea in 1947. Ophiobolnis graunis was isolated again from wheat and barley in 1976 and 1977. In 1977, perithecia of Ophiobolus were found on stems of rice, wheat and corn. Perithecia were formed on recommend varieties of wheat in the greenhouse as a result of artificial inoculation of mycelia into the soil. During 1977, Take-all of wheat and barley was quite severe. The result of survey made during this showed about 5 percent that the disease was present in Suweon, Daejeon, Yesan and Yongin. The Take-all infection causes remarkable decrease in the average weight of the grain, followed by a reduction in the number of tillers per plant and amount of gram per ear.
