Pesticide Applicator Core Training - Section 6 Rated A+

Pesticide Applicator Core Training - Section 6 Rated A+ 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). Discuss means of preventing off-target movement from: spray drift Spray nozzle operations in good condition, accurate product selection, and adequate weather conditions (low winds and mild temps). Discuss means of preventing off-target movement from: runoff Dissolvability of the chosen pesticide into the soil, avoid slopes leading to vegetation, spray nozzle operations in good condition, accurate product selection, and adequate weather conditions (low winds and mild temps). Discuss means of preventing off-target movement from: leaching Accurate product selection (strongly absorbed pesticide and non-persistent pesticides) and adequate weather conditions. Discuss general pesticide spill response procedures (liquid and dry) Inform supervisor immediately, confine the spill to the site and keep it out of water, do not let unauthorized people into the spill site, scoop up dry formulations and apply them onto the label-approved treatment site, soak up liquid spills with absorbent material and apply it onto the label-approved treatment site. Identify which state agency must be notified in the event that a pesticide spill threatens a waterway Indiana Department of Environmental Management State the purpose of an air gap, or an anti-backflow device To prevent back-siphoning into the water source. Identify what can happened in the absence of backflow
