Manage speed to eliminate spray drift

Plain text source: 
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...
