Abstract
The wheat variety "Nishinokaori" showed the highest susceptibility for foot-rot disease caused by Ceratobasidium gramineum among the four wheat varieties cultivated in Mie Prefecture. Increasing of acreage of "Nishinokaori" in Mie Prefecture may be an reason of recent occurrence of foot-rot disease in wheat. The lesion of foot-rot appears in around April. In Mie Prefecture, occurrence of foot-rot was most severe, when "Nishinokaori" was seeded in the early November. The disease was decreased when seeded in the middle November. The disease was hardly shown when seeded in the late November. Seeding later than the middle November was effective in order to control foot-rot disease. Seed treatment of the azoxystorbin was highly effective and practical to control the disease.
