Identification of leaf three emergence in winter wheat
Agronomist Richard Cromie demonstrates how to dissect a wheat plant to identify final leaf three – the target for T1 fungicides.
Richard Cromie shows how to identify leaf three for fungicide timings:
To identify leaves
Cut one layer at a time
Carefully peel back leaves
Discard outer leaves
Unroll all leaves to reveal the ear inside
Notice the leaf three must be fully emerged before T1 spraying
