Wheat School: Covering the flag leaf to manage disease and deliver yield

The flag leaf plays a key role in managing disease in the wheat crop.
On this episode of the RealAgriculture Wheat School, our resident agronomist Peter Johnson shares tips on identifying the flag leaf and how growers can use its emergence to guide their disease management strategy to protect yield at T2 timing (flag leaf) and T3 (when the emerging head fully clears the flag leaf).
How do growers know whether the flag leaf has emerged? In the video, Johnson shows how growers should look for the first node in the stem. The leaf attached to this node is considered leaf 4. Moving up the stem, growers can count the leaves in descending order - leaf 3, leaf 2 and leaf 1 - and then comes the flag leaf.
For a T2 fungicide application, especially in Western Canada where the crop is not sprayed at T3, the flag leaf should be fully emerged so the full leaf can be protected for maximum protection.

😮😮😮😮 $15.00/bushel wheat..???!! Is that CAN or USD? And to think I was just going to grow wheat for it's allopathic treatment of weeds on a field where I want an organic clearing of said weeds by next spring growing season. Also, wheat I believe will make an excellent green manuer. But at $15.00/ bushel....why the hell are we growing corn and beans in the USA..?? MADNESS!
