Spray drift is the physical movement of a pesticide through air at the time of application or soon thereafter to any site other than that intended for application (often referred to as off target). Not all pesticide drift happens during or right after a pesticide application. Some pesticides continue to evaporate for several days to several weeks after an application is completed (called vapor drift).
The drift of spray from pesticide applications can expose people, wildlife, and the environment to pesticide residues that can cause health and environmental effects and property damage. It is extremely important for those applying pesticides to ensure that spray drift does not occur. Many pesticide labels state to avoid weather conditions that favor drift. To apply pesticides against the label directions is a federal offence. Provincial authorities have set wind speed regulations; it is also against provincial regulations to spray pesticides in windy conditions.
At a wind speed of 15 km/hr the spray drift can travel 0.25km in distance. With the average property in Newfoundland being 15.24m across the front (or 50ft frontage), this would mean that 16 + properties in the direction of the wind would become contaminated by drift.
-Wind must be between 2 and 15 km/hr for ground applications
-Winds must be between 2 and 10km/hr for trees taller than 3meters
-Air Temperature must be below 25oC
-It must not raining nor is rain anticipated over the next 2hour period
-The relative humidity must be above 50%
