Don't let spray drift away
Author: Natalie Lee | Date: 17 Jun 2013
Spray operators can obtain advice on minimising the risk of spray drift by consulting the Grains Research and Development Corporation (GRDC) Fact Sheet Practical tips to reduce spray drift.
The resource advises that the risk of spray drift increases substantially when spray equipment travels fast during higher speed winds.To reduce the amount of spray drift spray operators are advised to avoid travel speeds above 16 to 18 km/h during higher wind speeds unless there is excellent boom height control and equipment is set up to minimise airborne droplets by providing spray quality which is coarse or larger.
Some other tips contained in the Fact Sheet include:
- Make the most of favourable weather conditions, especially wind speed;
- Maintain boom height to achieve double overlap, but no higher;
- Utilise unsprayed areas and downwind vegetative buffers.
