DuPont Pioneer Agronomy Report

Eastern Route - Day 4
Starts in Iowa City, Iowa and ends in Rochester, Minn.

Report from southern Minnesota

  • Weather has made this a challenging year in southeast Minnesota. We’re seeing variability in both corn and soybeans due to compaction, drowned-out spots and nitrogen loss.
  • We’re about 40 heat units behind the 10-year average. Heat units will be a primary concern so this crop can finish. All in all, we have a good crop in the field. If we get heat units it could be a great one.
  • Most corn is well into the milk stage. Some early planted corn is at ½ milkline while certain hybrids are denting.
  • Most soybeans are at R5-R6.
  • We’ve been lacking moisture the last 3 to 4 weeks and this has negatively affected both corn and soybeans. The rain we received this week should help us hold onto yields, especially in soybeans.
  • Minor disease pressure – gray leaf spot, northern corn leaf blight and Goss’s wilt. None have been at levels that will impact yield. Dry weather has been more of a factor.
  • We’re seeing a late hatch of corn rootworms likely caused by the late spring. Interestingly, we’re seeing more northern corn rootworms compared to others, but we’re not seeing heavy feeding on roots except for small patches here and there.
  • Corn aphids have come on strong this last week, but they’re not currently at levels that warrant treatment. Growers should continue to monitor fields.
  • Soybean aphids reached threshold levels and many growers sprayed for this insect.
