Frequent rains and cool weather in the spring of 2019 delayed the planting season by a month for Ontario corn growers. Now as harvest approaches growers are seeking answers to what are the risks to their late planted corn.

The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) field crop team created a resource answering common producer questions, such as:

  • How much time is expected before a killing frost?
  • How much more time will late planted corn need to reach maturity?
  • What is the fate of normal hybrids planted late?
  • What if reduced maturity hybrids were planted in early June instead?
  • What is the impact of corn not reaching physiological maturity prior to a frost?
