Some stalk are folding towards the top, I understand those as corn borer damage, hopefully I will still get corn out of some of them for where it's bent seems high, I suspect (but do not know) if they produce seed, they should be less likely to be inbred for the pollen was certainly donated by another? I do seen cucumber beetles, now that I know I have to look for another bug, both striped and dotted I believe. I had a lot of flea beetle pressure earlier in spring, I thought I had Stewart's wilt but I believe the damage was actually sugarcane beetles( they are recovering), I know I had quite a few plants lost to them. Do corn borer have continuous generation past emergence and I should spray often, of once the emerge there is a period of pressure when spraying is needed, then less pressure and resurgence in pest pressure. Should I be burning or chopping finely old stalks? If so How finely? I was planning on trying not to till much. The roatation goin corn, cowpea (possible later okra (wide spacing) planting with cowpeas), cereal rye, upland rice, cereal rye, peanuts/soy, daikon/rape, back to corn. I understand I should terminate brassica and till 30 or so days before planting corn. Is tilling really recommended much more than that to end bugs life cycles? Will the brassica only exacerbate the problem of the flea beetles, would trap cropping some of them be affective. I planted early my late planting emerged the day after our last frost.i feel this was good, but i should have sprayed flea beetle earlier, (it also worked perfect as far as rain went) I feel my collards may have been the reason for high flea beetle damage. Will rye spread disease to the corn by being near it, this garden is only 3000 sq ft. As far as I know the only disease I,be had is rust. Any other possible flaws in design? Will high crop residue be destructive? As for the corn borers in affected stalks you can often see a little hole at the base of the plant, in your area I believe you will have multiple generations in a year. I would spray once when the plants are young and then again right before silk emergence. I would spray nitrogen and sugar on the residue and try to naturally break it down. If you have southern rust it is awfully hard on corn and can lead to lodging, common rust is less concerning and a lot easier to find resistance to.

www.flickr.com/photos/158560771@N05/27685894657/in/dateposted-public/ Am I making the correct accessment of the photo? They keep on bending until they are folded over, or is this possibly environmental stresses? My early planting didn't seem affected but is in a different location. There appears only one plant that has common rust at this time, I suspect that as temperatures warm up it won't get worse. It is hard to tell if the bases have a hole in them because I hilled them. Why I thought it was corn borer was because once the row of holes on leaves started showing up so did the bent neck. Since I have hills it is possible once I harvest the cowpeas to throw all stalks in the ditches, throw cowpeas on top of that, then try to place soil on top of that. Would that be sufficient nitrogen? Or how much n per acre or 1000 sq ft (which Evers easier for you) to break down stalks, is a big bag of sugar per 1000 sq ft sufficient. I did leave one plant not hilled because it is in the onion patch, it looked like it was about to fall over and was leaning, but it has since has grown is now stronger, I think mesquakie is pretty stout, and the cobs start lower on the stalk then I have Seen, whiich I'm sure will help with lodging. Thanks for all you guys help. * after looking through more internet information maybe the row of holes is caused by bill bug feeding, can they do this type of damage or are the 2 unrelated?

I would bet on it being worm damage, my guess would be army worm. Spray insecticide in the whorl. I think 20 lbs actual n per acre would be a good start and that much sugar should be good, your jump starting micro organism, I would probably mow the trash or roll it down so it has soil contact.
