Managing eyespot using varietal resistance in the South East locations
Aims

This GRDC funded research program aims to provide growers with information which will reduce losses due to eyespot by improving our understanding of resistance responses of commercial cultivars and breeders’ lines to eyespot based on information from dedicated field screening trials.

Key messages
  • Know the risk of yield loss from eyespot before sowing a cereal - inspect stem bases (lodging does not always occur) in a previous cereal crop or take soil samples pre-sowing and submit them to PREDICTA B for analysis.
  • When selecting varieties with some resistance to eyespot, check their susceptibility to leaf/stem diseases to ensure they are not very susceptible to diseases such as stem rust.
  • Where eyespot pressure is low, varietal resistance alone will assist in reducing yield losses, but at medium to high level eyespot pressure, resistance alone may not be sufficient to provide good protection from eyespot.
  • Varieties with weak straw strength are more likely to lodge if affected by eyespot.
  • If applying fungicides for eyespot control - use the correct rate; apply before canopy closure (GS30-31); use high water rates; target the plant base (note that Aviator® Xpro® @ 500mL/ha is registered for eyespot control).
