Iowa DOA CORE Pesticide Applicator's License Practice Test

Rate describes the amount of chemical applied per unit area. It’s expressed as units like gallons per acre or pounds per acre and is what you set on the label to achieve proper pest control while staying within safety guidelines. Efficacy refers to how well the product controls the pest, not how much is applied per area. Residue is what remains on surfaces after application. Persistence is how long the product stays active in the environment. So, rate is the right term because it directly quantifies application intensity per area.
