Not everything yellow is a lemon locations
Aims

To look into the cause and effects of yellowing so that growers can make effective management decisions.

Key messages
  • Yellowing of wheat leaves, similar to the old ‘Frame yellows’ has been observed again in SA over the last few years.
  • There does not seem to be a clear cause of the yellowing.
  • Yellowing can lead to yield reductions, but also yield increases!
  • The effect of yellowing on the relative performance of varieties is far less than the effect of all the other traits that go into making a good variety.
  • If anyone has any ideas on what is causing this yellowing – send them through!
