PLANT PROPAGATIVE MATERIAL AS A PATHWAY FOR THE MOVEMENT OF EXOTIC PLANT PESTS INTO AND WITHIN THE GREATER CARIBBEAN REGION

Imports of plant propagative material (PM) may present a phytosanitary risk in two ways: 1) by introducing exotic plant pests associated with the PM, and 2) by introducing plants that themselves may become invasive. We found a high likelihood that pests, especially plant pathogens, are being spread between countries of the Greater Caribbean Region (GCR) through both legal and illegal movement of PM. Because of the relative ineffectiveness of visual inspection and the scarcity of diagnostic tests for pathogens, there is no easy solution to this problem. The PM pathway also leads to the spread of invasive plants in the GCR, where they cause considerable economic and environmental damage. Most invasive exotic plant species in the GCR were introduced on purpose. There are few safeguards in place to prevent this invasion from happening. Weed risk assessments and predictive weed screening tools may help mitigate this risk. This work was carried out in the framework of the CISWG Caribbean Pathway Analysis.
