How much nitrogen should I use for late planted corn?
Try to apply at least 25 to 30 lbs of nitrogen per acre at planting and the rest at layby. Sulfur continues to be a problem on corn this year.

Other than these recommendations nutrients should be managed as if corn was being planted at the regular time.
Do you need insecticides for late planting corn?
Herbicides should be applied based on the growers weed spectrum. No changes should occur just because the grower is planting late. The key issue will be whether there is a need for an application of insecticide to control corn borer or corn earworm. Growers who do not use a Bt hybrid should expect to apply a systemic insecticide as early as V8 to control these pests. Careful scouting should allow growers to respond to threshold infestations. However, these may not occur until after the corn reaches a height where ground equipment can no longer be used and the choice of insecticides is limited. This is why a Bt hybrid is so valuable in late-planted corn.

First, there is a much greater chance that corn will be severely damaged by late generations of European Corn Borer and Corn Ear Worm.
