The Plant Quarantine Barrier and Some Breaches in Papua New Guinea.

Abstract

The history of the Ordinances governing Plant Quarantine in Papua New Guinea is briefly given, with a short note on the prohibition or restrictions on the import of some plant species, especially those of the important subsistence food and cash crops. Some of the important plant diseases which have been excluded by the rigorously maintained quarantine barrier are listed. The major diseases which have breached the quarantine barrier are also listed and briefly discussed. Some examples of the type of plant and other material intercepted by the Quarantine and Plant Pathology staff are mentioned.
