Key messages
  • Growing conditions in 2016 were very wet and mild, with rainfall from May to September one of the wettest on record. Growing season rainfall was well above average with 491mm recorded at the site.
  • The conditions in 2016 did not favour the expression of crown rot, with only minimal disease observed. As a result there were no significant interactions between any of the seed treatments in this trial.
  • Durum wheat is more susceptible to crown rot than barley. The durum wheat variety Aurora was used in this trial and was out-performed by the barley variety LaTrobe, yielding significantly lower.
  • At tillering, the NDVI of treatments not infected by crown rot were significantly higher than those infected by crown rot. At flowering there was no significant difference in NDVI between any treatment
