Regional Crop Report South West,   18 May 2007
Winter Wheat
Comment on current growth stages Field conditions
Most crops now at boots split to ear emerged with anthers showing on the earliest. Crops have thrived with the moisture and have made a lot of growth in the last week although they still remain shorter than usual. These shorter crops allow rain splash even more freedom to move Septoria from lower to upper leaves so robust triazole fungicide rates must now be maintained. Wet and windy weather has made flag leaf spraying difficult.
