The powdery mildews of beans were surveyed in the monthly sown bean plants at TARI from September 1984 to June 1986. No diseased plant was found in soybean while mungbean and adzuki bean were much more susceptible. Generally, the occurrence of this disease in mungbean was earlier and more serious than in adzuki bean. Mungbean and adzuki bean cultured in Autumn showed higher degree of severity than in Spring, especially in adzuki bean, and there was not much susceptibility difference in any plant stage. Most spores were disseminated during the day, especially at noon, while few were released during the night. It showed that there was not higher disease incidence while investigating in Ping-tung area (Autumn, 1984; Autumn, 1985) and in Chia-yih area ( Spring, 1985), but the disease incidence was higher in Pei-kang area (Spring, 1986). From our climatic data, we believed that the distribution and severity of powdery mildew were directly and indirectly influenced by the environmental factors. Therefore, to lessen the occurrence of powdery mildew, it might be better to sow crops in early Autumn or late Spring.
