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.
