Winter wheat:   Crops at the thirteen monitoring sites are reaching flag leaf emergence (GS37-39).  Septoria is the only disease present at all sites, levels tending to be lower in the east.  Amounts of rainfall continue to be low and the current septoria risk is not expected to increase imminently. 

Yellow rust has been recorded at 7 sites so far, and though severe at Caythorpe and increasing at Boxworth is now absent from 3 previous sites. Oakley and Robigus are the most severely affected.    

Brown rust continues to be absent from crops in the monitoring network but current hot weather may increase risk. Mildew incidence is regionalised with only 4 sites affected (all in the West Midlands). Risk of all diseases except brown rust will remain low while the hot, dry weather continues.  

 
Winter oilseed rape:    Levels of light leaf spot remain low with the disease mainly evident in the south east. The extended flowering period has increased the period of susceptibility to sclerotinia and temperatures are now favourable for spore production. However, the current dry weather will ameliorate risk due to reduced petal sticking.
