Regulated non-quarantine pests: concept and application. International Standard for Phytosanitary Measures

Some pests that are not quarantine pests are subject to phytosanitary measures because their presence in seed and planting material has economically unacceptable effects on the intended use of plants. Such pests are known as regulated non-quarantine pests (RNAVO), they are present and are often widespread in the importing country.
Where official control measures are applied to seeds and plantings produced in countries to protect them from such pests, identical or equivalent phytosanitary measures may also apply to these pests present in imported seeds and plantings of the same type intended for identical use.
