Particle and vapor drift
Particle drift occurs when a pesticide moves through the air as droplets during application.
Vapor drift occurs when applied pesticides volatize, or turn into fumes and move through the air.
Can harm other plants, injure people or animals, and pollute surface water
Follow label, apply during suitable weather, and use appropriate sprayer settings
