Yuna trial results - pre-emergent control of brome grass in wheat locations
  • To evaluate and compare the weed control and yield of Sakura with commercial standards.
  • To demonstrate efficacy & crop safety of Sakura when sown with grower’s machinery.
Key messages
  • All treatments were safe to the crop except for Sakura 118 g/ha + Sencor 150 g/ha which resulted in biomass reduction at all assessments.
  • This was in part due to a couple of rows being sown into the inter row that contained herbicide which re-sulted in the death of some plants.
  • This mixture would not be recommended on conventional wheat. An overall crop bio-mass rating was taken 106 DAA rated Sakura 118 g/ha as 100% with the other treatments benchmarked against it.
  • The crop was water stressed at this time. Inspection of the crop heads found they were not filling to potential with small grain and empty husks common across the trial.
