Highlights

• 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?
