Wheat Pete's Word, May 22: Wide leaves, stripe rust, rolling beans, weevils, and S-starved knolls


What a difference a week makes!

For many parts of Ontario, corn and soybeans are up and loving the heat, but the mid and eastern parts of the province are still struggling to get the crop in as conditions are quite wet.

The early warmth has also brought on stripe rust in wheat (scout!), more alfalfa weevils (scout!), and lodging due to high biomass. Speaking of biomass, wheat is pushing out some incredibly large flag leaves — could that be a bad thing? Find out on this episode of Wheat Pete’s Word.

  • May has been warm!
  • Ahead of the 10-year average
  • There is five-leaf corn happening in southern Ontario
  • There is some weird stuff happening out there with split coleoptiles
  • Silage talk: rye, triticale, the fall seeding crops are ready! The SP harvester is chugging with all the volume
  • Lodging showing up in wheat that hasn’t headed (no PGR)
  • Even with PGR some winter barley is lodging
  • Don’t feel bad if this isn’t your season of heat. Some areas are beginning pummelled by rain
  • You can’t plant into mud
  • New Brunswick fall seeded spring wheat survived the winter
  • Pete’s wheat crop is not going to love this over 25 degree heat
  • Big fat flag leaves, big biomass
  • Red clover in late May looking great even in massive wheat crops
  • THE UGLY: ALERT stripe rust! Make sure it’s stripe rust, but if you have it, you cannot wait
  • Scout, and then scout again
  • It moves so fast
  • A generation of rust spores is just 5 days
  • Nothing to orange in as little as two weeks
  • Protect the head! No strobis
  • Fusarium risk is high in many areas too. FHB sprays stop rust, too
  • Alalfa weevil — if more than a week away from cutting and more than 3 larvae per stem, you must control the weevils
  • Are cereals going to save us? In the wet, wet middle and far east, the soil is wet and not fit
  • Eroded knolls and faces of slopes — Sulphur issues!
  • Warm air but is soil staying cool? It’s possible
  • N loss measurements: compost vs fertilizer
  • Urea in the N that is prone to loss, ammonia is what gasses off. Ammonium doesn’t
  • Too big clover? Need to knock it back
  • Rolling beans pre or post planting, what’s the emergence/crust risk? There’s this video too
  • Go shallow on soybeans with good moisture?
