Abstract
In order to investigate invading and epidemic rules of rape sclerotinia stem rot of ‘Zheyou 50’ and promote the development of brassica campestris industry, this paper studied the outbreak regularity and epidemic model of rape sclerotinia stem rot according to field investigation and infection. The result showed that machinery direct seeding rape was good for the occurrence of sclerotinia stem rot for the reason of late seeding and high density. The period from water damage appeared to wilting death was about 15 days only, when latent period from nature mycelium to invade to total was about 8-17 days with a infected rate up to 13.2%. The epidemic dynamic showed to be linear-rise trend. Flowering stage was the main epidemic period of disease. Diffusion of rape sclerotinia stem rot fitted a logistic function model.
