Crop topping cereals for annual ryegrass 2007 locations
Aims

To investigate the effect of crop topping cereals for annual ryegrass control with nonselective herbicides.

Key messages
  • Glyphosate and glufosinate applied to flowering annual ryegrass give better control compared to later applications. While paraquat and diquat can be applied later.
  • Paraquat 0.8L/ha or glyphosate 2.0L/ha applied to flowering ryegrass gave over 90% control of viable seed set per head.
  • Glyphosate at 1.0L/ha or glufosinate above 2.0L/ha gave more than 65% control of ryegrass seed heads.
  • Herbicides applied to barley at the soft or firm dough stage of grain fill did not reduce grain number, weight or viability.
