These trials taking place in southern Victoria and Tasmania were conducted to examine the response of more disease resistant
varieties to triazole and strobilurin fungicides in the near absence of disease.
Last season there were small yield increases of 6% to the Folicur treatment at GS39, with no benefit of the split application over the single dose. However though positive, these yield effects were not significantly different to the untreated. Strobilurins created no positive effects other than at the very highest rate and again these were not significant.Other than keeping a watching brief for the further spread of stripe and leaf rust strains affecting Mackellar, it does not appear to be a candidate for fungicide input.
