Fungicides for net–type net blotch of barley 2016 trial report

Page last updated: Thursday, 1 September 2016 - 3:09pm

Please note: This content may be out of date and is currently under review.

In 2015, barley net-type net blotch came into prominence due to adoption of susceptible barley varieties such as Oxford. This trial evaluates the efficacy of seed dressing and in-furrow fungicide against barley.

In 2015, barley net-type net blotch was detected at many locations. Some foliar fungicide applications to control the disease failed. In addition, the pathogen which was detected in the lower Great Southern developed resistance to old triazole base fungicide products. Therefore, there is a need to evaluate the effectiveness of the new generation seed dressing and in-furrow fungicide products against early barley net-type net blotch management.
