The United Nations General Assembly has declared 2020 as International Year of Plant Health to raise global awareness on how protecting Plant health can help end hunger, reduce poverty , protect environment and boost economic growth.  The Theme is “Protecting Plants, Protecting Life”.

Portugal issued a set of Four Stamps on International Year of Plant Health.

Date of Issue 25 Oct 2020.        

0.53 Euro – Daktulosphaira vitifoliae -The grape phylloxera is an insect that originated in North America, appearing in Europe for the first time in 1863,

0.86 Euro – Bursaphelenchus xylophilus – The pine wood nematode is considered to be one of the most potentially destructive species for coniferous forests. This microscopic worm is transmitted to trees by an insect – in Portugal, the pine sawyer beetle. Originating in North America, the pest spread around the world, moving first to Japan in the early 20th century, then to the rest of the Asian continent. In Europe, the nematode was identified for the first time in Continental Portugal in 1999 and has been found more recently on the island of Madeira and in Spain.

Currently, the pine wood nematode is one of the main phytosanitary threats facing our pine forests and its presence has caused a range of plant protection measures to be adopted: monitoring coniferous forests and the insect vector, identifying and removing trees with symptoms of decline, and applying heat treatment to wooden pallets and packaging if they are intended for transportation beyond Portugal or into the buffer zone, a 20-kilometre security strip along the border with Spain.


0.91 Euro – Ceratitis capitata– Known as the Mediterranean fruit fly, this pest attacks a variety of crops and wild plants, laying its eggs in their fruit.

2.00 Euro- Rhynchophorus ferrugineus -The palm weevil attacks several species of palm trees, causing damage which can lead to the death of these plants without the necessary treatment
