主要疾病

油菜菌核病，这种病会威胁到叶片和植物的茎和荚果。一开始会有淡褐色的病斑，之后还会成为灰白色，甚至会腐烂，外表出现一层白色的絮状物。

霜霉病

这种病在油菜的生长期间都有可能发生，进而会造成叶片干燥，花序变得不仅奇形怪状而且更加肿大。如果叶片遭遇这种疾病，它的正面就会有一些不太明显的淡色微黄的斑，而在背面会有白色的霜状霉，对结实造成影响，减低菜籽的质量。

花叶病

这种病主要是在感染病害之后，嫩叶的上面会有明脉的症状，有些甚至所有的叶脉都会变成暗黄色，之后会有一些花叶的情况。还有些许叶片形状会变得异常，最严重会整棵植株都萎缩变形，甚至枯死。

防治方法

在种植时可以选择抗病性比较好的品种来种植，进行适当的筛选和溜选。

一定要在油菜的幼苗期就预防蚜虫，勤查虫，一旦发现就要立刻用喷药灭虫。可以使用48%的乐斯本的乳油。

要进行合理有效的施肥，特别是底肥要用足，磷钾肥要加强施用。

在刚开始发病的阶段，特别是开花期之前，要有效及时的施用肥料，一次控制治疗病害。
