Wheat Pete's Word, May 10: Quality forage timing, cold temp fallout, and two-pass fungicide strategy


This week’s (almost!) cross-Canada Wheat Pete’s Word is packed full of great questions, worries about cold temperatures, solid timely answers on field management, and at least one alert, alert, alert!

Your host Peter Johnson tackles questions on harvesting cereal rye (soon! this week!) while keeping compaction in mind, if corn seed is going to be damaged by this cold wet weather, another reminder to test soybean seed, and a red alert on stripe rust for Ontario.

Listen below, and be sure to check out the summary, as he mentions two videos in this episode — links follow in the summary.

  • Quality vs. compaction: cereal rye loses feed value quickly after boot stage and is loving these cold temps. Be ready to harvest
  • What temp does corn grow at? Will it rot? There is concern about cold water uptake for anything in the ground right now…what damage will it do? Some. You’ll have to scout. Corn can handle being in the ground for weeks though, and the yield potential is still there.
  • Is it time to change corn hybrid maturities? Not yet! See more in this Corn School.
  • Soybean quality and germ — test it and find out about “abnormals”
  • 2,4-D and glyphosate ahead of conventional soybean plus tillage — can I do this? Should be fine from a residual perspective but is 2,4-D the best option?
  •  Stripe rust alert! You can’t wait to spray if you have a susceptible variety. View more in this Wheat School.
  • Two-pass fungicide protocols — when do you do the first and second pass in wheat? Depends on if it’s spring or winter wheat, if stripe rust is an issue AND if you’ve got your weeds controlled
  • 10.5″ row wheat, going down with 100 pounds of MAP…can I still do this? Probably, but you’re getting closer to upper limit
  • Winter wheat and wild oats — will I have to control them this spring? Likely not. Yay, winter wheat competition!
  • If you have no N on winter wheat yet – is it too late? As long as it’s before pollination, it will respond. If you have none, at all, get some on there.
  • Sulphur deficiency on wheat is showing up. Correct it asap!
  • Spring barley. Can I put red clover on, too? YES. Single cut if you do, because it’s easier at harvest, and use 6-8 pounds per acre
