Identification of leaf three emergence in winter wheat

Article overview

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
