Abstract
The occurrence of melanose was investigated on yuzu at Goheung and Boseong in Jeonnam province in 1997 and 1998 seasons. The disease occurrence on leaf was initiated from late May in 1997 and early May in 1998, severest in late of June on leaf, and in case of fruit, initiated from early July in 1997 and late June in 1998 with a peak in early August. The disease was occurred in twenty days more earlier in 1998 season than 1997 season. We think this was caused by temperatures during April and May. And it was supposed that the disease severity on the severest late of June was closely related to the rainfall and relative humidity during June. The disease severity was severer in old tree than the young.
