We studied a correlation between the change of‘inu-no-ashiato’, a leaf blight ofZoysiagrasses, and the number of an isolated asporogenous fungus which could be associated with the disease occurrence in field. Patches of this disease were observed in test field Wakayama city area first in early June and early October. Maximum, average and minimum temperature of these month were 25-27°C, 21-33°C and 17-20°C respectively. There was considerable rainfall immediately before occurrence of the disease. The isolation frequency of asporogenous fungus was quite high with accordance of appearance observed. However, this fungus was hardly isolated from fields after the development of the disease reached its maximum.<BR>Control effect of Procimidone fungicide to this disease was noted at a dose rate of 0.3 g/m² using 0.2 to 1/m²of water. A longer period was required in fall to reduce the disease by fungicides than in early summer, suggesting that earlier application of an effective fungicides could be necessary in fall to recover from the disease.
