Leaf and glume blotch

Causal organism - Septoria nodorum (Stagonospora nodorum)


Cultural control

Disposal of crop debris by ploughing can help prevent early infection. Few varieties are particularly susceptible.

Chemical control

Seed infection can be reduced by a number of seed treatments. It is essential to protect the flag leaf and the ear from disease by appropriate fungicide sprays when wet weather occurs between GS32 and GS59.
