Assessing the influence of strobilurin application on the nutritional requirement for malting barley locations
Aims

The overall objective is to determine the influence of strobilurin fungicide application on the nitrogen requirement for malting barley.

Key messages

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.
