The overall objective is to determine the influence of strobilurin fungicide application on the nitrogen requirement for malting barley.
The trial was subject to a moderately dry finish and 2-3 week dry period in October, which curtailed grain fill, and resultant yields. Despite this, under moderate Scald (Rhynchosporium) pressure, a 2-spray fungicide programmes based on Tilt (propiconazole) and Tilt plus Amistar (azoxystrobin) gave a 6 and 7% yield increase (0.22 —0.25 t/ha) over the untreated (mean of nitrogen treatments). Though individual nitrogen levels differed, the 2-spray Tilt programme showed a small margin improvement, however the
strobilurin was not cost effective in this trial.
