Brown leaf spot (BLS) is the common disease on in cassava worldwide, and it is also the important disease in China. Based on the previous study, the investigation and popular characteristic research in China was launched in our lab. The result showed BLS was widely occurred in the main cassava planting areas of China. BLS was seriously happened at partial cassava plantations, and most varieties were sensitive. In three years, the systematic investigation of three cassava varieties in two sites was finished. We found BLS usually occurred in the middle growing stage of cassava, increasing as the disease progressed, then popular and damage at mid-later stage. Field test studied illustrated Prochloraz, Carbendazim, Propiconazole had a better control effect for BLS, which was suggested to be used in cassava plantation.

Key words: cassava, brown leaf spot, occur pattern, fungicides effect in field trials
