Herbicide efficacy in ryegrass control locations
Aims

To assess the efficacy of three herbicide types on stubble covered soil.

Key messages
  • No significant difference in ryegrass control was found between plots treated with any of the three pre-emergent herbicides tested.
  • Though not statistically significant, the trial demonstrated a trend of increased herbicide efficacy with increasing herbicide carrier volume.
