Which statement is listed as a deposit definition that involves pesticide mixtures?

• A. When two pesticides are blended and then applied.
• B. A pesticide remaining immediately after an application.
• C. When two pesticides may not be synergistic.
• D. The area to be evacuated.

Answer: (A)

In pesticide terminology, a deposit is the residue that remains after application on the target surface or area. When two pesticides are blended in the spray tank and then applied, the resulting residue is a mixed deposit containing both active ingredients. This directly involves mixtures and how they leave a combined deposit on the treated surface. The other statements describe deposits that aren’t about mixtures (a single pesticide residue), or they describe concepts like pesticide interactions (synergism) or safety zones, which aren’t about deposit definitions involving mixtures. So the statement about blending two pesticides before application best fits a deposit definition that involves pesticide mixtures.
