Aims

To determine the relative herbicide tolerance of Sturt and Moonlight.

Key messages
  • See Milestone 2 for weather interpretation.
  • Emergence was 55 plants/m2 for Kaspa, 45 plants/m2 for Moonlight and 42 plants per/m2 for Sturt. Targeted densities were 50 plants/m2 for Kaspa and Moonlight and 40 plants/m2 for Sturt.
  • All varieties responded similarly to the herbicide treatments. No visual damage was observed for any of the herbicide treatments. This was probably due to the dry conditions experienced.
  • Grain yields were strongly correlated with weed populations, i.e. herbicides that gave good
    weed control resulted in highest grain yields. To overcome this affect, we used weed score as a covariate. This showed that Imazethapyr applied at double rates caused a significant reduction in yield (approximately 40%). This implies that the safety margin for this chemical is relatively low, therefor growers need to use caution and avoid overlapping within their crops.
  • Sturt appears to have the best adaptation to dry environments with yields 50% greater than
    Kaspa and Moonlight. This is the same trend as has been observed in the breeding program.
