Septoria fungicide update and latest developments in rust management locations
Aims

To explore the field performance of foliar fungicides for control of STB.

Key messages

• Genetic mutations in the Septoria tritici blotch (STB) pathogen Zymoseptoria tritici can differentially influence the performance of triazole fungicides in the laboratory.
• There should continue to be a focus on the principles of an integrated disease management (IDM) approach to control diseases such as STB, using rotation, cultivar resistance, later sowing, and other aspects of cultural control to compliment fungicide control.
• New research on foliar fungicide indicates that the principal fungicides still give good in-field control of STB up to 30 days after application when applied at full label rates.
• There are significant differences in disease control amongst the different fungicide products and rates of application when monitored leaves are assessed more than 30 days after application.
• Single spray timings of foliar fungicide for control of STB made during the late tillering phase gave less effective disease control than applications made at first node (GS31). Spray application delayed until flag leaf gave the poorest control of STB but gave superior leaf rust control later in the season.
