Wheat Pete's Word, Oct 17: Horsetail control, cleaning corn, and new answers for cereal rye


Harvest has picked up in both Western and Eastern Canada, though the challenges facing each region are unique.

On this episode of Wheat Pete’s Word, Peter ‘Wheat Pete’ Johnson tackles late season weed control decisions (mostly: just don’t), diseased corn crop management, and shares some new findings on including cereal rye as a cover crop.

  • Above average soybean yields are a-ok, remember. Even if you don’t get the 60, 70, or 80 bushels/acre.
  • Reports are there are edible beans out there with over 50% pick. Some out that have been sprayed a month, sitting. Reports of soybeans and edible beans that are split, sprouting, on the ground or going right through the combine
  • Wheat drills are rolling! Good soil conditions in some areas. Two-thirds of the way to a million acres? We’ll see
  • Oh gosh. The corn crop. Where it’s bad, it’s so bad. Some fields are above 20 ppm for vomitoxin. That’s harsh. Have insurance? You must report damage to Agricorp, and you need rejection letters. And markets are changing quickly. (Hear more on how we got here, here).
  • Do not let this corn sit in a wet bin or the truck
  • Screenings coming out of the dryer/bin coming out at 60 ppm — cleaning is worth it!
  • Walk your fields, husk length seems the same, even with shorter cobs and tights husks makes all of this worse
  • Sample everything, test everything, and please report in with varietal differences
  • Maritimes: hard frost in late September. They’re dealing with Grade 4 and Grade 5 corn. Ouch
  • Questions; horsetail control. Be very careful with MCPA in the corn crop next year. It can reduce yield for sure. But right now, there’s not enough plant matter to absorb product, and nutlets are already in the soil. Wait for spring.
  • Weed control ahead of wheat? Six hours ahead is workable. You can spray after seeding, but NOT when emerging.
  • New findings on planting green and cereal rye. For the most, we know that plant green is a no-go with corn, but in soybeans, it might work. We see a 1.5 bu loss on soybeans, only AND that cereal rye crop can really help weed control (Thanks Mike Cowbrough and Peter Sikkema) keep your seeding rates up!
  • When to terminate that cereal rye? Terminating the stand the day off planting didn’t knock back yield, and actually killing it too early meant more Canada fleabane. But it’s not all positive — soybeans were a growth stage behind, which impacts the wheat crop, for sure. More to learn!
