Knockdown herbicide treatments for sub-tropical grass establishment locations
Aims

To determine whether a single knockdown herbicide can be used for successful establishment of sub-tropical grasses to reduce the wind erosion risk from double knockdown applications.

Key messages
  • Establishment densities were higher at both sites following the double knockdown treatment.
  • Sand infill was less with the single knockdown treatment, but these differences were not statistically significant.
