It's so shocking that I found my sweet corns have stood dead with trunks,leaves and fruits turning yellow.
While I was looking at corns to find the cause of the phenomenon, I found some holes on their trunks as the photos shown below.
Finally, I found the cause of the death of my corns.
It's a kind of bugs that had intruded into them and made the trunks hollow.
What I saw in the hole on trunks is a pupa of European cornborer.
I had to determined to cut out all of the corns to prevent expansion of the bug's attack.
This is my first try to raise corns and I've learned how serious bug's attack is....
I would like viewers to share this situation and give me your ideas to prevent that.
