摘　　要：研究结果表明 :油菜菌核病子囊盘形成高峰期防治两种类型油菜的菌核病均优于子囊盘形成始盛期和盛末期的效果 ,故子囊盘形成高峰期就是油菜菌核病的最佳防治期。以菌核萌发形成子囊盘的高峰期作为防治指标 。This paper was concerned with preventing rapeseed from the stem rot by controlling apothecia sprouted from sclerotium at different stage with the FENMEILING 36SC sprayed to two types of oilseed. The effect on controlling the stem rot of two types of rapeseeds (Brassia napus and B. campestris) at summit phase of apothecia was superior to at other phases. The author thought the suitable phase of preventing rapeseed from the stem rot was at the summit phase of apothecia. Phenology of the pathogen can be regarded as a basis of applying fungicides to apothecia.
