Washington Pesticide Laws and Safety Practice Test

Manufacturers or formulators of pesticides are required to include certain information on the label to ensure the safety and proper use of the product. Options A, B, and D do not provide necessary information for the use of the product. A manufacturer's email address may be included for convenience, but it is not a requirement. The product's price is also not relevant to its proper usage. A detailed usage guide is important, but it is not the only required information. Therefore, the most appropriate answer is C - the name and address of the company. This is important as it allows users to contact the manufacturer in case of any questions or concerns about the product.
