KEEP YOUR PRE-EMERGENCE APPLICATIONS ON TARGET

Pre-emergence herbicide treatments create one of the most challenging targets for application. With no crop to intercept the spray, extra care must be taken to avoid drift, and to achieve good coverage of the soil surface.

Nozzle selection to hit the target. The Syngenta Defy 3D Nozzle is designed to give all round coverage of soil clods and surface. Alternate nozzle angle to face forwards and backwards along the boom.

Boom height to prevent drift. Maintain height at no more than 50cm, or use the Defy 3D Nozzle, designed to give greater flexibility while maintaining coverage and drift free spraying.

Forward speed to balance work rate and efficacy. Working too fast increases turbulence that can result in increased drift and poor coverage. Defy 3D Nozzles are designed to work best at speeds of 12-14 kph.

Water volume selection. Nozzle choice has been shown to be far more effective at assuring surface coverage than increasing to high water volumes. Defy 3D Nozzles work highly effectively at 100 l/ha, and gave the greatest benefit over flat fan nozzles at 200 l/ha.
