90% Drift Reduction Nozzles delivering great performance in the field
Results of new pre-emergence application trials have highlighted the importance of boom height, forward speed, water volume and nozzle selection to target soil surface

Pre-emergence application technique will have a significant impact on the efficacy of all Black-grass control treatments.

Final results of dedicated application trials at the Syngenta Black-grass Innovation Centre near Cambridge have revealed new techniques to achieve better control, by ensuring more spray reaches the target and delivers good coverage of the soil surface.

“The key is to get the maximum spray on to the target soil surface in the field – which will in itself enhance results," advocated Syngenta Application Specialist, James Thomas.


“Importantly the 90% drift reducing technology makes real step change in pre-emergence weed control if spray conditions are in any way compromised,” he advised.


Key research finding for the Rules of Pre-Emergence Herbicide Application include:

  • 50 cm maximum boom height
  • Less than 12 km/hr forward speed
  • 200 l/ha water volume
  • Use 90% drift reducing nozzles
