APHA adds nine pests and diseases to the Plant Health Risk Register

Nine pests and diseases have been added to the Plant Health Risk Register while updates on olive restrictions and bemisia tabaci have been issued.

New tree pests placed on the register in November are:
  • Rusticoclytus rusticus – grey tiger longhorn, a polyphagus beetle of broadleaved trees.
  • Platypus quercivorus & Raffaelea quercivora – Japanese oak wilt and its vector, damaging oak species.
  • Melittomma sericeun – Chestnut timberworm, a wood-boring beetle of oak, chestnut and elm.
  • Elsinoe coryli – hazelnut spot anthracnose, a fungal disease of hazelnut.
  • Pseudomonas syringae pv. Ulmi – bacterial leaf spot, a bacterial disease of elm.
  • Chionaspis pinifoliae – pine needle scale, a scale insect of pine.
Crop pests added include:
  • Aleurocanthus camelliae – tea spiny whitefly, a pest of tea and other camellia species.
  • Pests recently reviewed on the Risk Register:
  • Aproceros leucopoda – elm zig-zag sawfly, a defoliating pest of elm.
  • Tomato chlorosis virus – ToCV, a virus of tomato spread by whiteflies

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
