What is the legal responsibility of an applicator in relation to the off-target movement of pesticides?

An applicator's legal responsibility in relation to off-target movement of pesticides is referred to as "Applicator Responsibility". This means that the applicator is accountable for any unintended or accidental spread of pesticides beyond the intended target area. This could include actions such as reading and following label instructions, properly calibrating equipment, and taking necessary precautions to minimize drift or run-off. Option A, point-source pollution, refers to contamination coming from a specific and identifiable source, which could include pesticides but is not specific to just applicators. Option B, nonpoint-source pollution, refers to contamination that comes from multiple or diffuse sources, making it difficult to identify and assign responsibility. Option D, runoff, refers to the movement of liquids, including pesticides, over the surface of the land and into bodies of water, which is a potential consequence of an applicator not fulfilling their responsibility.
