Key messages

 The fungicide treatments were effective in reducing the incidence of foliar disease (namely Scald and Net From Net Blotch), prolonging green leaf area and significantly increasing yield at this site in 2020.
 In two susceptible cultivars a single spray application of Prosaro at GS31 increased grain yield on average by 0.62t/ha and shifting to a two-spray strategy with the addition of Radial at GS39-49 increased yield by 1.5t/ha. The addition of the seed treatment Systiva at sowing to this treatment did not further reduce disease infection levels or increase grain yield. These results highlight the later follow up application is likely to be more effective and important than fungicide usage prior to GS31.
 The yield responses observed from the two foliar spray strategies are correlated to both a reduction in Scald and Net Form Net Blotch but also an increase in green leaf area.
 Grain quality responses were significant, noticeably the later fungicide application increased test weight by 2kg/hL in RGT Planet.
 The benefits of maintaining a green leaf during grain fill are influencing grain quality in malting barley consistently across the high rainfall zone and even in the absence of a yield response should not be overlooked.
