Study on the Biological Characteristics of Pathogen of Wilt of Cucurbit and Germicide Determine

This paper conducted the biological characteristics and germicide determination for the pathogen of wilt of cucubit. The results showed that there are evident different on the morphologic characters, but they also had similar shape and properties.In the process of cultivation, 25℃ was the optimum temperature for mycelial growth.The higher spore germination rate was at 20-30℃.The sporulation different formae speciales was nonsensitive under various temperature.For various pH treatments, the optimum pH value was 6 for spore germination.5 fungicides(Jiangenbao?Miaojundi?Wudi?Genbizhi and Chongchabao)showed good effects on controlling against Fusarium wilt of cucubit.
