General Comments

EU listed spider mite pest of conifer, occasionally intercepted in the EU on juniper bonsais from Eastern Asia. Some uncertainty about its potential to thrive under UK conditions. EU derogations allowing import of juniper bonsais to be kept under review. Bonsai importers and traders should be aware.
