Wheat Pete's Word, Aug 14: Weather woes, wheat after corn silage, and corn insect ALERT


Another week, another important reminder: get out there and scout!

On this week’s episode of Wheat Pete’s Word, host Peter Johnson covers everything from the diverse adversity in weather advents across the country, to the incredible pests showing up in Ontario corn fields (think: earworm, western bean cutworm, rootworm, Japanese beetles, and grasshoppers). Take a listen now, or download the podcast for later.

  • How does USDA figure that there’s more corn acres planted, and that the yield is up?
  • From frost in Peace River County to hail in Oregon – what is up with this weather?
    • Corn earworm is showing up! Climate change is real, and we are going to have to start paying more attention to this pest. Get out there and scout, and be sure to identify it, as we’re limited in our insecticide options, and genetic resistance options with this insect.
  • Finding western bean cutworm, but no eggs? DON’T SPRAY HALF RATE! All this does is help the insect population develop resistance to that group of insecticides.
  • There seems to be a resurgence in corn rootworm, and they’re going to move to late pollinating fields because they like the silks. Get out there and scout! Look for Japanese beetles and grasshoppers too. If there’s no silk, there’s no pollination.
  • Soybean insects? Anyone?
  • If planting winter wheat early, how do you manage the risks of aphids and barley yellow dwarf virus? Hessian flies?
  • What about wheat after corn silage? Will tillage help the risk of fusarium?
  • A conversation on fall wheat and take-all.
  • Can I grow wheat on wheat? First off, that’s an automatic 10 per cent yield loss, plus, greater risk of disease.
  • Why do I have low protein?
  • Sow thistle in newly seeded alfalfa – what do I do? Consider repeated cuttings.
