Fungicides for crown rot locations
Aims

To determine whether new or commercially available fungicides, combined with novel or standard application methids, can provide significant control of crown rot caused by the fungal pathogens Fusarium pseudograminearum and F. culmorum. 

Key messages
  • To date field trials funded by GRDC project DAS00136 have not been able to show that application of fungicides to seed provide significant reductions in yield loss caused by crown rot.
  • Fungicides applied to seed or in-furrow at seeding can provide some suppression of pathogen growth through the plant early in the season (as measured using DNA techniques) but this effect is gone by early grain fill.
  • In crop spray applications targeted at the base of plants have shown small yield benefits, but these benefits are not consistent between sites and across seasons.
