spray drift risk

Catalogue: GRDC 2014 Research Summaries
The Australian grains industry is facing economic loss due to regulation of existing pesticides and associated application due to continued adverse spray drift events and lack of current suitable data to support current best practice... There is also potential increased regulation of pesticide products due to current pesticide use practices and stewardship including residue management and spray drift... Efficacy studies will be conducted on grass and broadleaf weeds using medium and coarse spray qualities so growers will be confident that weed control will be maintained with these sprays...

Attention to detail can help prevent spray drift risk.. GRDC Western Regional Panel member and adviser Chris Wilkins encourages growers to access up-to-date GRDC resources to help them achieve good spray coverage without creating a spray drift risk... "The GRDC remains focused on providing growers and operators with the tools required to continually improve their spraying practices and minimise the risks associated with spray drift," he said...

Manage speed to eliminate spray drift.. A Canadian study showed that, during higher wind speeds of about 20 kilometres per hour, machinery travelling at about 30km/h almost doubled the amount of chemical contributing to spray drift risk, compared with machinery travel speeds of 8km/h... Spray operators are advised to avoid travel speeds above 16 to 18km/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...
