Stem rust control in wheat locations
Aims
  • To evaluate the efficacy of different foliar fungicides against stem rust (Puccinia graminis f.sp. tritici) in wheat.
  • To account for possible shortages in foliar fungicide supply, products were tested over as wide a rate range as possible.
Key messages

Stem rust control

  • High rates of fungicide (in most cases the recommended rate on the label) gave significantly superior stem rust control compared to the low rate tested when assessed on the leaf sheaths of hte plant 27 and 50 days after applicaiton.
  • Propiconazole (Tilt) gave significantly poorer stem rust control than the other fungicides tested at full label rates (or high rates).

Yield data

  • The average response to fungicide was 9% at the low fungicide rate, 17% at the mid-rate and 16% at the high rate, though there was no statistical significance between fungicide rates.
  • All products tested at the highest rate of fungicide application significantly increased yield, except Prosaro and Tilt Xtra. Opus and Amistar Xtra were the only two products to significantly out yield the untreated at all three rates tested.
