What is required for nursery stock that does not meet standards of cleanliness?

In the context of nursery licensing regulations, if nursery stock does not meet standards of cleanliness, it can still be sold under specific conditions, such as a written agreement. This agreement typically outlines the circumstances under which the stock is considered acceptable for sale, along with any necessary treatments or inspections that must occur before the sale or prior to use.

This allows for flexibility in managing stock that may have minor issues while still ensuring that the public and other businesses are informed of the condition of the plants. It also emphasizes the importance of proper documentation and transparency in transactions.

The other options, while sounding reasonable at first glance, do not reflect the regulations that allow for continued sale under controlled conditions. For instance, total destruction would be an extreme measure unless contamination or other serious issues were at play. Increased inspection frequency typically does not mitigate the ability to sell but rather ensures compliance with standards. Simply stating that the stock cannot be sold at all would not support the practical approach many nurseries take when managing their stock while upholding regulatory compliance.
