TOKYO, March 20 (Xinhua) -- Japan's cherry blossom trees in at least 18 prefectures have been infected by a mold disease, which could make the trees unable to produce flowers and sometimes kill them in about 10 years, local media reported on Monday as the cherry blossom season is approaching in the country.

    According to a survey carried out by the Flower Association of Japan, at 53 locations in 28 of the nation's 47 prefectures from July 2004 to December last year, the country's emblematic cherry blossom trees at 25 places in 18 prefectures were found infected with the contagious mold disease known as witches' broom, which does not threaten the health of humans.

    The association warned that the existence of even one affected tree indicates it is highly likely the disease has already spread out in the area and has recommended immediate efforts to move the lesions from the affected trees, Kyodo News said. Enditem
