What information should NOT be included on lawn care product markers?

The correct choice emphasizes that directions for mixing products should not be included on lawn care product markers. This is primarily because mixing instructions can vary greatly between different products and formulations, and may require specific measurements or conditions that could lead to misuse if misinterpreted or inadequately detailed on a marker. Lawn care product markers are typically designed to provide essential safety and usage information that ensures proper handling by consumers. Including detailed mixing instructions could inadvertently lead to accidents or improper use, which is why it's typically recommended that such instructions be provided in a more controlled environment, such as an accompanying product label or user guide rather than on the marker itself.

Meanwhile, the business name and contact information, type of pesticide used, and instructions specific to the product's use are critical pieces of information for consumers. They ensure that users can easily identify the product, understand its safety profile, and follow appropriate usage guidelines as necessary for effective application and safety compliance. Each of these elements plays a vital role in consumer safety and informed usage, making them important to include on product markers.
