瞿麦的经济和药用功能，相信大家已经了解的差不多了，现在我们一起来了解一下瞿麦在种植过程中的病虫害及其防治方法。

瞿麦的根腐病及防治

根腐病是瞿麦当中很容易发生的一种病症，顾名思义，这种病是从由根的腐烂造成的，一开始的时候并不会表现得很明显，而且我们也不容易察觉，当发现有长势不好或者是异常苗的情况下，一定要检查瞿麦是否患上了根腐病；在发病的中后期，瞿麦就开始慢慢发黄，根部逐渐腐烂，最终的结局无疑是死亡，所以，根腐病的关键就是发病的初期，发现之后，及时治疗，就会避免这样的事情发生。瞿麦的根腐病的防治方法很简单，根腐病会发生扩散，因此发现有病的瞿麦之后，要及时的在其周围撒上一层草木灰或者是常见的石灰，以防止病症的扩散，然后，将有病的植株拔出后，喷洒药物去除病菌即可。

瞿麦的黑粉病及其防治

黑粉病名字的由来是这种病症会使植株长出瘤状物，瘤状物的内部有黑色的粉末。黑粉病主要是对瞿麦的花序和果实造成危害，使之长不出完整的果实，影响植物的价值，严重者还会造成一定的经济损失。黑粉的防治要从播撒瞿麦的种子做起，在种子还没有播撒的时候将浸泡在冷水中，然后在热水里冲一到两秒晾干后播下就可以大大减少黑粉病发病的几率，成株中如果有发现得了黑粉病的植株，就要及时拔出，并喷洒药物除菌。

瞿麦青虫和黏虫害及其防治

青虫和黏虫都是通过危害瞿麦的根部进而影响瞿麦生长的，所以在这里将青虫和黏虫害放在一起说，发现瞿麦植株上有青虫和黏虫的时候要不需要拔出植株，只需要对植物喷洒药物进行杀菌消毒处理，严重的时候，要隔一个周喷洒一次药物，直至害虫全部消失为止。
