Wheat Pete's Word, May 12: Cold temps, the rule of three, and mixing instructions


What’s the cold weather doing to wheat crops, to the insect populations, and to the soil?

In this episode of Wheat Pete’s Word, host Peter Johnson answers these questions; plus he talks road safety, cool stuff, insects, weed questions, dirt questions (ahem, soil), and more.

  • Farm safety includes road safety!
  • USDA report out today, crops prices keep going up; what a difference a year can make, financially, and to our mental health

  • It’s been cold!
  • Ultra-early seeded wheat and barley is up in Alberta!
  • Duration of a frost makes all the difference. Killing temps: at least two hours
  • Does the calendar trump the rule of three? What stage is the wheat at?
  • Pete did a Wheat School on identifying the flag leaf. Find it here.
  • The wheat crop seems short? What about lodging in a short crop? Lots of questions to mull over
  • Fungicide because of septoria in the canopy, going to go through with another fungicide.
  • Remember that fungicides control and stop disease from developing, it doesn’t make it disappear
  • Apparently it’s not too cold for cereal leaf beetle eggs at Simcoe County! Start scouting!
  • Starlings dive bombing a wheat crop? Stems cut up into three or four inch segments. Almost for sure sawfly
  • Alfalfa weevil on the Niagara peninsula. Get scouting
  • ATS and herbicide mixing instructions. Talk to your dealer
  • Compacted areas in a field that were subsoiled last year. Dandelions! Hard to control. Spray now, wait a day to three days, work it, then get the soybeans in
  • Soils have been staying wet and there’s been little evaporation with the cold weather.
  • But, the weather will change! So watch your tillage, know you’re going to lose moisture
