  • Corn:
    • 02:20 Flag test update (Also, watch: Flag Test Measures Emergence Impact).
    • 04:23 Fairly significant crusting in some areas — learn the right way to break a crust.
    • 06:51 Huge difference in emergences.
  • Edible Beans:
    • 07:22 Planting has started. Don’t forget, long-term averages indicate best yields come from planting in the first week of June.
  • Hay:
    • 08:04 Hay harvest has started. Johnson can’t wait for low-lignin alfalfa…
    • 08:43 You can not fall asleep if you’re going to take winter/cereal rye as a hay crop.
  • Stripe Rust:
    • 09:20 Now being found north of London. Some varietal concerns…
    • 10:34 10-14 day latency period. Once those pustules develop, the damage is done. Spray it before that happens!
    • 11:09 It does stop developing over 25C, but starts up again after hitting 20 or lower for five or six hours. You can not afford to wait.
  • Fusarium:
    • 12:26 Think: timing, direction of spray, droplet size, boom height, wind.
  • Double Crop Soybeans
    • 13:15 We’re 5-7 days ahead of schedule with wheat — could we plant soybeans after harvest?

One thought on “Wheat Pete’s Word, May 25: Applying Fungicide, Planting Soybeans and Breaking the Crust

  1. Peter – Appreciate the support and positive comments on DC soybeans. I predict that there will be a bump in interest for DC soybeans this year due in part to the growing season still being slightly ahead of the longterm average. I agree, moisture at planting is one of the critical production factors – encourage growers to plant soybean seed into moisture. I have seen DC soybeans emerge from 4″ planting depth. Note: This is only a DC soybean planting recommendation – not suitable for early spring planting. Our Syngenta DC soybean research work during the past 6 years shows that grower’s need to receive approximately 12″ total of rainfall during JULY, AUGUST, SEPTMBER and OCTOBER to consistently break 30 bu/acre – optimum if evenly distributed across entire growing season. If any of your growers need specific variety recommendations Syngenta has developed some excellent tools to assist in optimizing the selection of varieties to mitigate production risk while maximizing returns from an Ontario DC soybean production system.
