Wheat Pete’s Word, April 17: Nitrogen Q & A, resistant lamb’s quarters, and leadership in action

Germinating vs over-wintered weeds in middle of April, 2024

Calendar dates can be thrown out when it comes to scouting for weeds and early nitrogen application in Ontario, as growing degree accumulation is well ahead of normal.

As part of this week’s edition of Wheat Pete’s Word, host Peter Johnson discusses the implications of crops being ahead of schedule, the confirmation of glyphosate-resistant lamb’s quarters in Quebec, and much more, including answers to your questions on spring weed control and nitrogen rates. Pete also shares some lessons learned regarding leadership at the RealAg team’s annual summit last week.

  • Do you want to be right or have influence?
  • Slow down, take a breath
  • Bad news, there is lamb’s quarters confirmed resistant to glyphosate in Quebec. Read more here.
  • The rain in Ontario last week was excessive in some areas
  • The Peace Region of Alberta is excessively dry and under threat of fires
  • A winter canola plant in flower yesterday in the deep south! Wow!
  • The growing degree day accumulation is well ahead of average for Ontario. (That means scout for weeds)
  • That also means nitrogen management on wheat is somewhat more complicated
  • Know your growth stages of wheat for N application
  • When is the risk of denitrification loss the highest?
  • Zero-N strips can teach lessons
  • MESZ strips — there are 10 pounds of N, too
  • Sometimes it’s better to ignore the calendar!
  • Nitrogen rates on forage triticale
  • Chickweed and dandelion control in corn
  • High speed discs and fertilizer placement
  • Happy National Soil Conservation Week!
