Which of the following aspects is part of a pesticide's label?

A pesticide label is a legal document that provides essential information about the product, how to use it safely, and the conditions under which it is effective. Manufacturer contact information is a critical component of the pesticide label because it allows users to reach out to the manufacturer for further guidance, to report adverse effects, or to inquire about specific product details. This ensures that users can obtain necessary support and information related to the safe handling and application of the pesticide.

While price information may be relevant for purchasing decisions, it is not included on the pesticide label itself. Application best practices, while important for safe pesticide use, generally appear in guidelines or instructional materials but may not be specifically detailed on the product label. Expiration dates are also not typically included on pesticide labels; instead, the effectiveness of the product may depend on its storage conditions and continuous adherence to label instructions. Since the focus of a pesticide label is to provide clear instructions and necessary information for safe use, manufacturer contact information is essential, and thus, the correct aspect identified from the choices is indeed that.
