Which term describes increased activity resulting from the interaction of two or more active ingredients in a pesticide formulation?

• A. Synergism
• B. Drift
• C. Adsorption
• D. Absorption

Answer: (A)

Synergy occurs when two or more active ingredients interact to produce an effect greater than the sum of their individual effects. In a pesticide formulation, this means the combined action is amplified, making the overall pest-control effect stronger than what each ingredient would achieve alone. That’s exactly what the question is asking for—the term that describes increased activity due to interaction between ingredients. Drift refers to the pesticide moving through the air to non-target areas, not to how ingredients work together. Adsorption is the process of a chemical binding to surfaces like soil or plant parts, which affects movement and availability but not the interaction between active ingredients. Absorption is the uptake into plant tissue or an organism, which again is about movement into the target, not synergy.
