Abstract:
In the present study，the generation and germination of spore of Cercospora sojina in soybean was studied under different temperature and humidity in Heilongjiang province in order to reveal the relativity between occurrence of frogeye leafspot of soybean and meteorological factors.The diseased leaves in fields were collected to investigate the spore generation and germination under extreme high and low temperature，and different temperature of soybean leaf surface and canopy humidity.The results showed that the optimum temperature for spore germination is 18℃and the canopy humidity is 80%，the average number of spore is 5.6 spores per square millimeter and 10.0 spores per square millimeter resepectively.The spore can germinate normally at the temperature ranging from -30℃ to 30℃.It was indicated that the severity of frogeye leafspot has positive correlation with the average humidity and overall rainfall from June to August，but has nothing to do with mean temperature.
