Aims

To make farmers more aware of herbicide drift and the management practices which reduce the potential for drift to occur.

Key messages

A drift demonstration was set up at the BCG Main Field Day site. Different nozzles which delivered different droplet sizes, two travel speeds, a boom height above the recommended level and wind speed at 15km/h did not result in significant drift. This is probably due to a relatively high Delta T of 5, a set of conditions that occur when small droplets evaporate before they can cause much damage. The windy conditions also caused turbulence resulting in a lower likelihood that droplets would be deposited on a susceptible plant.
