2016 was also a high disease year for Ramularia leaf spot (RLS). In
fact, in some paddocks RLS was so hard to control that questions were raised
about the profitability of the fungicides applied. But in Bayer’s barley fungicide
support trials they paid handsomely with an application of Delaro followed
by Aviator Xpro giving an average yield increase of 3.3 t/ha and a margin over
fungicide cost of $863/ha*.
*Average of 2 Bayer trials 2016/17 located in South Canterbury. Average yield increase compared to the
untreated 3.3 t/ha, wheat price used $325/tonne, fungicide programme Delaro 750 ml/ha (GS32) and
Aviator Xpro 1.0 L/ha (GS39) costed at $175/ha.
