Exceptional corn canopy health may lead to higher test weights this fall. Lower than normal disease pressure this season has allowed canopies to keep photosynthesizing, resulting in lower than expected corn denting. This boosts the potential for higher test weights…Hear more

GDU Shortening in Corn

Delayed planting doesn’t necessarily translate equally to delayed maturity. Corn can shorten its growing degree unit (GDU) requirements for reaching physiological maturity by about 7 GDUs per day of delayed planting after May 1…Hear more

In normal seasons, corn earworms are not present in sufficient numbers to greatly damage yield. However, late planting increases the risk of earworm damage, which can reduce yield and creating mycotoxins.
