Velocity - evaluation of a 2 spray strategy for wild radish control locations
Aims

To evaluate which combination of an early bromoxynil based herbicide and follow up post-emergent herbicide will provide the best weed control and Return on investment (ROI) in a system approach to wild radish control in cereals.

Key messages
  • All treatments were safe to Mace wheat in this trial with minor crop flecking recorded from all Group F treatments with symptoms diminishing within a fortnight.
  • None of the yields in this trial were significantly different from the untreated however all treatments applied at Spray B recorded significantly (P≥5%) lower contamination from wild radish pods in the sample than the untreated. Pod separation was not conducted on treatments that had either Velocity or Jaguar at spray A All treatments with a Spray A were assumed to be AUH2 for ROI analysis due to the high levels of weed control.
  • Velocity 800 mL/ha (4.16 t/ha) applied at application A only recorded a higher yield than Velocity 1 L/ha when applied at application B only (4.11 t/ha), demonstrating the advantages of early weed control in competing with the crop for nutrition.
