Re: It Wasn't Raccoons In The Corn...

I was thinking it might happen this year, since it is so dry this month...squirrels got into my corn as well.
I had a block#1 started and then I filled out the rest of the rows with block#2, delayed by 3 weeks or so. This was Bodacious, a 75 day yellow SE. I have grown Incredible (85 day yellow SE) the last few years with no trouble but figured I'd try this shorter one for the first couple blocks to get earlier corn. The first block came in on its own without me having to hand pollinating. First ears came in. Some initially had 2nd ears going, just a few days later, but most 2nd ears were delayed some and I could see that the pollen ran out. Still I did not hand pollinate. I wanted to see what it would do, hands off. Those first ear's silk started getting darker, maybe 10 days back. The stalks kind looked rough on a lot, and I noticed holes in some ears and some stalks. I started picking 4 days back,
Day 1 took 8,
Day 2 took 8 the next day and already I saw some ears that looked disturbed. Like a bug eaten one was super sugary, but maybe peeled back a bit as well.
Day 3 took 8, then looked through the rest closely. There were a bunch damaged, 4 or 5. A lot of stalks have bore holes near the bottom. And almost all the second ears that weren't solid cobs were drying/rotting. So I picked them all and chopped the stalks off. I'd say about 1/2 the stalks had european corn borer holes through the cut right above the roots. All together I pulled 92 ears from the first block, but the last 66 may have significant damage, bug or squirrel. I put them in the fridge for now.
Day 4 looked at the 2nd block( adjacent to first) and even though they are not near ripe, being 3 weeks delayed, now a bunch of them were torn up. So I cut down the second block. No corn borer holes on them. I left the ears on the stalks and brought the stalks home. I may get something out of them. Somewhere around 3 doz stalks.
So...I planted two blocks next to each other. That was breaking a rule I made a few years back. And I did it not once, but twice. Blocks 3 and 4 are adjacent. With the Incredible the last few years I have not had any squirrel damage. But once they get in there...they come back daily. And the next block, if any ears are showing, gets ripped up just as bad. This corn taste about the same as Incredible, I don't believe it is much sweeter, like the supersweet that used to get ripped up. It has been so dry though, that I almost expected it, honestly. We'll see if they go after the tomatoes now that I took the corn down.
The unexpected was the European Corn Borer...which I admit does not make much sense since Maize is a new world crop...but I won't argue with the book. Says it was first discovered near Boston 50 years ago (book is a dated golden guide) and they will bore into other types of plants as well. I take it to be a moth that ate something else for millions of years but when it found corn grown in europe, it earned itself a proper name. These things gnaw a BB size hole in and then turn, usually down it seems, right through the heart of the stalk. I have never seen these before. Earworms, sure, but not borer. But, there are a few acres of corn planted about 150 yards west of my blocks, prevailing upwind that is, so I imagine the smell was on the wind, and some of these moths caught the scent of all that corn but shortstopped at my little blocks. This is the first time since I've been growing sweet corn blocks that there is a corn planted nearby. It seems notable that the younger block of corn does not have any damage from borer while the older block had approx 50% affected.
I just hope there are no borer or squirrel damage in the next corn, blocks 3 and 4. Probably a month or more out from that being ripe. I was really hoping a for a good week or more of fresh corn from each of these initial blocks. I do have the other half of block #2 in my backyard, but that is only a couple dozen if that and lots of squirrels here as well.
