Importers in the European Union must require since 2009 from their importers a second certificate in addition to the usual phytosanitary certificate : Araceae plants like Philodendron, and also Marantaceae, Musaceae, Persea spp and Streliziaceae must be controlled for the detection of Radopholus similis, a common parasite found in nurseries in the world. This control is a costly and time consuming constraint and the plants can only suffer as it is also exerted on roots. Each plant in a small shipment is controlled, not samples.
