Increased vulnerability of wheat varieties to Irish septoria strains confirmed

Septoria blotch is the primary disease of the Irish wheat crop

Unrolling the leaves is the only way to assess if you are applying the leaf-3 fungicide to the correct leaf in winter wheat. Control of septoria is the biggest challenge. File Picture. 

Teagasc has confirmed that Irish strains of septoria are able to overcome a source of genetic resistance present in a range of near-market winter wheat varieties.

This is the conclusion of a significant study led by Dr Steven Kildea - Teagasc crops researcher - that has been accepted for publication in the journal Plant Pathology.
