Aims

To demonstrate the effect of water rates and droplet size on the efficacy of pre-emergent herbicides in retained stubble systems in the medium rainfall zone of South-East of South Australia.

Key messages
  • Overall the efficacy of pre-emergent herbicide control of ARG increased with increasing water rates. This was particularly the case with Sakura, supporting the results from Western Australia.
  • There was no significant difference between weed control treatments (both between and within herbicide treatments) on end grain yield.
  • This trial experienced extremely dry conditions throughout the season, as such grain yield was limited.
