Plant quarantine
/plænt ˈkwɔɹənˌtin/
Definition
Plant quarantine is the temporary isolation of a new, sick, or pest-exposed plant from other plants to prevent the spread of insects, mites, fungi, bacteria, or viruses. In gardening and horticulture, it usually means keeping the plant separate for a set observation period and monitoring for symptoms or pests. The term can also refer to official restrictions on moving plants across regions to stop regulated plant diseases and invasive pests.
Practical Relevance
- Hidden pest control: plant quarantine helps intercept insects, mites, nematodes, and disease-causing microbes before they spread to collections, landscapes, nurseries, or farms.
- Protection during symptom-free periods: Some infected plants look normal at first, especially with viruses or latent fungal infections, so holding them apart can reveal problems before contact with other plants.
- Value for propagation and trade: It is especially relevant for cuttings, bulbs, tubers, and imported houseplants because these can carry pests or pathogens on or inside living tissue.
- Limits on cross-contamination: Keeping new or suspect plants separate reduces the chance that shared tools, water splash, potting surfaces, or nearby foliage will move pests and diseases between plants.
- Support for regulatory plant health: In horticulture and agriculture, plant quarantine underpins inspection and movement rules that help slow the introduction of serious invasive pests and pathogens into new regions.
