Alternaria, water-using crops, and rain in August — LIVE! Q&A with Wheat Pete


Peter “Wheat Pete” Johnson is back for this episode of RealAg LIVE! and he’s brought his own fancy charts and weather requests.

Listen below or download the podcast for later, and get a mid-season agronomy update for Ontario, some crop info for water use, and a nitrogen comparison show-down.

  • But first, a crop update: rain in all the wrong places and none of the right ones in Ontario
  • Alfalfa after wheat comes off? Make sure it’s in by Aug. 20, please
  • More pasture, hay, in the Peace? In those wet areas, what could go in now to use up water. Oats or rye is the better option to just use water (but if you’re looking for something to harvest next year, wheat would work)
  • Hey, it spreads out the work load. For that reason, grow some wheat!
  • Pause: which do you prefer, whisky vs. vodka?
  • UAN vs. Ammonium nitrate, which is better? A pound is a pound is a pound of nitrogen, but form does play a role in the availability and loss risk of each type.
  • Anthracnose showing up. It’s always weather related!
  • Diseases in corn — it’s been dry, can you skip a fungicide? A fungicide does not drought proof a crop, FYI
  • Disease pressure is likely lower this year, but if you’ve got hogs, you’re controlling DON, for sure. But if you’re not, it’s hard to spend that money.
  • Why did the wheat die early and now I’ve got black dust all over my combine? On light ground is worse. Why? Because it’s all about water holding capacity (helllllo, organic matter). Alternaria or something similar grew on the wheat after it died.
  • Don’t miss tomorrow’s Diagnostic Days! Ep. 2
  • Western bean cutworm peak flight is approaching! The timing isn’t lining up for fungicide and insecticide as well this year. Likely two passes. Scout for those eggs! WBC need moisture, so rain now could make it worse.
  • Can you still put N on post-anthesis if it’s dry? What about burn? Go at night, ahead of rain, or if you’ve got fairly high humidity. Ahead of rain is better.
  • Soil sampling after wheat, using stubble as your guide. Post-harvest, there’s plenty you can learn from your fields.
  • Remember that beneficial insects are so important — if you kill the beneficials (and not the spider mites, for example) the pest populations just explode. Check out Pests & Predators Podcast.
  • Provincial average for corn? Likely 10% below trend line
