Elders resistance boom results 2002 locations
Aims

To assess the effectiveness of a range of herbicides on a number of ryegrass populations throughout the ‘Liebe’ area with an ‘in situ’ method of resistance testing.

Key messages
  • The levels of resistance reported are from targeted problem ryegrass paddocks and are not a true indication of the area's overall resistance status.
  • There is a high level of ryegrass resistance to 'fop' chemicals in these tests.
