Meanwhile following the recent finds of Xylella fastidiosa in traded olive, new measures have been introduced through the Plant Health England (Amendment) (No.5) Order 2018, which will take effect on 26 November.
The order will extend the statutory notification scheme for imports of certain tree species from other EU member states to include Olea europaea (common olive) to provide additional protection against the introduction of Xylella fastidiosa.
There is also a new Defra Pest Alert on Bemisia tabaci and poinsettia crops, following issues earlier in 2018 with supply of young Poinsettia plants and other interceptions made of the pest entering the UK protected zone
