Which of the following details is required on seed labels?

Seed labels are critical for providing essential information to consumers and regulatory bodies. One of the mandatory details on seed labels is seller information. This information typically includes the name and address of the seller, which is important for traceability and accountability in the seed industry. It allows buyers to identify the source of the seeds they are purchasing and provides a means of contacting the seller for any inquiries or issues that may arise with the seed quality.

In contrast, while other aspects such as transport regulations, seed purity levels, and growth conditions may be relevant in certain contexts, they are not universally required on seed labels. For instance, seed purity levels are critical for determining the quality of the seed and may be included in certain jurisdictions or specific types of seeds, but they do not universally appear on every label. Similarly, growth conditions are important for cultivation but are not necessarily a requirement for labeling. Transport regulations would pertain more to logistics and compliance with transportation laws, rather than seed labeling itself. Therefore, seller information holds a key position on seed labels as it directly relates to consumer protection and industry standards.
