Oilseed rape applications
Autumn applications
For grass weed control in oilseed rape, operators face the extra problem of crop shading emerging target seedlings – the best rates of control are achieved by early applications at the one to two leaf stage. Finer droplets are required to wet shinny grass leaves and generate sideways movement to get under leaves.
| Water volume | 100-200 l/ha |
|---|---|
| Nozzle choice | For pre and post emergence applications and early volunteer control the Defy nozzle forward and back is recommended. The Hawk nozzle will also work well. |
| Application speed | 12 km/h is optimum |
| Other comments | Alternating the angled Hawk nozzles down the boom reduces drift and increases coverage, especially in cloddy seed beds, keep pressure low to reduce drift |
Spring applications
If targeting the petals/pods use the Hawk nozzle. For greater distribution down the plant use the Amistar nozzle.
| Water volume | 100 l/ha |
|---|---|
| Nozzle choice | Amistar or Hawk |
| Application speed | 12 km/h |
| Other comments | The angled Hawk nozzles leave most spray in the top third of the canopy, if this is the target then this is the nozzle. For desiccation the Amistar nozzle is better suited to target all parts of the canopy. |
