Zone 7, NY LI. It's been quite hot/humid here lately with some recent days having scattered heavy downpours.

Possibly its corn flea beetle damage, which are also hosts for Stewart's Wilt and SW is endemic in some areas of NY. Did you save the packet of seeds so we can know the variety name to see if its SW resistant?

I'm not sure if I saved the seeds but I'll report back. What's odd to me is that I started the seeds indoors and then transplanted them to a brand new raised bed that I built and filled with a mix of top soil, compost, peat, etc. That leads me to believe that it may not be SW. I have noticed flea beetles all around the garden though, not too many, Neem Oil seems to be keeping the pop. down. No other gardens around my area.

Even if it is SW, your corn looks to be far enough along that the harvest won't be too seriously affected. But if you google Stewart's Wilt you'll find tons of pictures to compare your corn against. And it could just as well be some other ailment; there's no shortage of insect, bacterial and fungal agents that attack corn.

In my experience, corn doesn't like to be transplanted. Just plant seeds next year, transplanting is a shock which it's not evolved to expect. You mention that you planted 12? Hardly enough to get good pollination, be interesting to see if the cobs are full or partially full of kernels come harvest. I'd suggest at least a 6X6 grid of seeds spaced one foot each way at a minimum. If space is the issue, buy corn locally and use that space for bush beans, etc. Much more return for your effort.

Agree that is not enough corn to pollinate with, Z7 you should have enough time to plant seeds, The way your pictures look you should be ok but as far as the ears go I agree with exmar.
