Name the 2 types of drift.

Explanation:
Drift occurs in two forms: particle drift and vapor drift. Particle drift is the movement of spray droplets or particles carried by air currents during or after application—smaller droplets are particularly prone to being blown off target by wind. Vapor drift happens when the pesticide volatilizes into a gas and moves with air; this is more likely with highly volatile chemicals, higher temperatures, and certain atmospheric conditions, allowing the vapor to travel long distances from the application site. Understanding both helps you select appropriate droplet size and nozzle type, apply under favorable weather, and use practices that minimize off-target movement.
