The term "pesticide residue" refers to the remaining pesticide that can be found on treated surfaces and in the environment following the application of the pesticide. This residue can include not only the original chemical components but also any metabolites or breakdown products that remain after the pesticide has been used.

Understanding pesticide residue is crucial because it relates to both the efficacy of pest control and potential impacts on human health and the environment. Residues can be found on crops, in water sources, and on surfaces in areas where pesticides have been applied, and their presence can have significant regulatory and safety implications.

The other options focus on different aspects of pesticide usage and chemistry. Breakdown products pertain to what happens to pesticides after they decompose, while active ingredients relate to the specific chemicals that act to control pests. The application rate describes how much pesticide is applied but does not directly define what pesticide residue is.
