The result showed that bamboo rust occured more frequently in moist, shadow bamboo field. The winter spores mainly distributed on the bamboo stems below 1 m. Scraping winter spores on newly infected bamboo stems from January to February was effective. Painting 20 % triadimefon EC （diluted 5 times） on winter .spores twice in early October,late March the next year could rescue more than 90 % of the infected bamboo and the amount of newly emerged winter spores was low.
