Key points
- Post-emergence applications of Bladex + Gardoprim, Gardoprim + Glean, Turonex and Trophy each provided good control of the range of grass weeds investigated in this trial
- Bladex + Gardoprim, Gardoprim + Glean and Turonex caused some visual damage in wheat at the standard rate. 75% of the standard rate of all treatments except Achieve and Escort produced slight damage in barley
- The other herbicides evaluated had a spectrum too narrow to be useful, although good weed control of specific weeds occurred
- Soft brome was best controlled with Bladex + Gardoprim or Gardoprim + Glean
- Prairie grass was best controlled with Turonex or Glean + Gardoprim
- Both Italian and perennial ryegrass were well controlled with Bladex + Gardoprim, Turonex and Gardoprim + Glean. Perennial ryegrass was particularly susceptible to Escort
- Topik + Treflan, Turonex and Achieve were highly active on oats. Low rates of Bladex + Gardoprim looked to be a possible option as a grass weed herbicide in oat crops
- Turonex was the only registered treatment and provided useful control of the grass weeds including oats
- Herbicides applied at GS11 appeared to give useful broadleaf weed control
