Pesticide Applicator Core Training - Section 6 Questions with complete solutions Define spray drift Spray drift happens at the time of the application, when air movement carries small spray droplets or dust particles away from the application site. Site Conditions: Air Movement/Wind and Temperature. Define vapor drift Vapor drift happens after pesticide applications, when the pesticide evaporates into a gas and is carried away from the application site. Site Conditions: Air Movement/Wind and Temperature. Define runoff Runoff is the movement of water over the land surface, away from its point of origin. Site Conditions: Runoff: Slope of the land, soil moisture content, vegetation, weather/precipitation and pesticide characteristics. Define leaching Leaching is the movement of water down through the soil profile. Site Conditions: Soil Texture, Organic Matter Influence, and permeability. Discuss means of preventing off-target movement from: vapor drift Spray nozzle operations in good condition, accurate product selection, and adequate weather conditions (low winds and mild temps).
