What is the maximum safe amount of a pesticide allowed on a crop called?

The maximum safe amount of a pesticide allowed on a crop is referred to as "tolerance." This term specifies the legally permitted level of pesticide residue that can remain on agricultural produce without posing a risk to human health or the environment. Tolerances are established by regulatory agencies, such as the Environmental Protection Agency (EPA) in the United States, based on scientific assessments designed to determine the safety of pesticide use.

In contrast, concentration generally refers to the amount of a substance in a given volume or mass, which does not necessarily relate specifically to regulatory maxima for pesticide residues on crops. Permissible limit can be too vague as it does not indicate the precise regulatory frameworks followed for pesticides specifically. Usage rate pertains to the amount of pesticide that can be applied per unit area during application but does not directly address the residue levels that are legally acceptable on food products. Therefore, tolerance is the precise term used in the context of pesticide regulation for crops.
