Which of the following is NOT a type of data required for pesticide registration?

The requirement for pesticide registration involves extensive data to ensure safety and efficacy before a pesticide can be used. This process includes various assessments such as evaluating potential residue levels in water sources, examining the environmental fate of the compound (how it behaves and breaks down in the environment), and testing short-term toxicity to laboratory animals to determine any adverse effects.

Costs associated with pesticide application, while important for marketing and economic considerations, do not fall under the safety or environmental impact assessments required for registration. Regulatory agencies focus on data that ensures the product's safety for human health, wildlife, and environment rather than economic factors. Hence, costs are not part of the scientific data required for evaluating a pesticide’s registration.
