Preventing Parthenium hysterophorus from entering and spreading in the EPPO region
Parthenium hysterophorus (Asteraceae) has been recommended for regulation to EPPO member countries since September 2014 and is listed in the EPPO A2 List. A Pest Risk Analysis (PRA) record and a PRA report (consisting of a summarized version of the PRA record) are available on the EPPO website and a datasheet on the species will also be published in the December 2014 issue of the EPPO Bulletin.
In addition to these documents, an article summarizing the main elements of the PRA will be published in the December 2014 issue of the EPPO Bulletin. This article informs the readers about the probability of entry of the species via the different pathways within the EPPO region (i.e. as a contaminant of used machinery, grain, seed, growing media attached to plants for planting, travelers), the probabilities of establishment and spread and the magnitude of its potential agricultural, environmental and social impacts.
