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 (N.B. Use of products and rates lower than label rates in this trial does not constitute a recommendation).  
     
Key messages
  • Fungicide application for stem rust control was more effective and economic where product application was made prior to visible infection in the crop.
  • Where fungicide application was made at an early stage of grian fill (GS 71) disease control of stem rust was inferior to the same products applied at the same rate 16 days earlier at 50% ear emergence (GS 55).
  • Higher rates of fungicide (label rates for stem rust control) need to be employed for this disease in order to give effective control; this is particularly the case with fungicides containing a single active ingredient such as tebucanazole (e.g. Folicur) or epoxiconazole (e.g. Optus).
  • The strobilurin/triazole mixture of azoxystrobin/cyproconazole (Amistar Xtra) gave excellent stem rust control at its highest rate but its higher cost reduced its economic return.
  • The performance of propiconazole (e.g. Tilt) against stem rest was poor in terms of disease control, relative to other products tested.
