So, I grew corn for the first time this year and it was really fun and successful. The stalks grew tall and produced cobs. One unfortunate problems was that some pests got into my corn and got into some of the cobs. I cut off the bad parts but was still disgusted by the damage. I found out that they are called corn sap beetles and are attracted to the smell of damaged corn. So, how do I prevent those little insects. Is there a certain spray? Any varieties that are resistant? Another quick question, what can I do about mutant corn? I hate all the cobs that have overgrown kernels next to the underdeveloped ones. I read that it has something to do with the corn silk? They are edible, just kind of odd, but as long as I can eat them I'm fine, but is there any way to prevent it?
