Spring Malting Barley Series - T1 on Spring Barley
As rainfall and temperatures have increased over the past week, many spring barley crops are now approaching the T1 fungicide application timing. Eoin Lyons Teagasc/Boortmalt Joint Programme Advisor, outlines disease control strategies for barley crops and what products will give best control.
The third video in our spring malting barley series focuses on T1 fungicide applications for spring malting barley.
During the last video, Eoin discussed the importance of avoiding stress on barley plants as low rainfall and temperatures were having an impact on crop progression throughout the region. However, in the past 10 days, higher temperatures and rainfall have meant that that crops have grown considerably and are now approaching the T1 fungicide application timing.
Teagasc trials, carried out over a number of years, have shown that a 2 spray fungicide program is sufficient for control of harmful diseases in spring barley. The first application should take place at the mid-late tillering stage with the aim being to protect developing tillers from diseases such as Rhynchosporium and Net Blotch.
The type of products to use should be a Triazole plus SDHI/Strob mix with products such as Siltra/Elatus Era/Decoy-Comet and many others being most suitable. The trials have also shown that a half rate of any of these products will be sufficient for disease control
The take home messages are:
- Apply at the mid to late tillering stage of crop growth
- Apply a Triazole plus SDHI/Strob mix
- Half rates of any fungicide will give sufficient control
