Bacterial Plant Diseases
15 Oct 2018
The handout of our presentation on Bacterial Plant Diseases at the BCPC Diseases Review at Cambridge on 12th October 2018 is now available on the downloads page. After a brief summary of the recent AHDB review of bacterial diseases, we presented a case history on the management of Xanthomonas in transplanted vegetable brassicas.

Carrot field storage - New report

Onion neck rot report
15 Jun 2016
Our report on onion neck rot pathogens and seed treatments can now be downloaded from the HDC website. Around 26% of 2015 commercial bulb onion seed lots were found to be infested with neck rot. Both of the main neck rot pathogens Botrytis aclada and B. allii were detected, including from fungicide-treated seed. Some seed lots contained one or the other species, but some contained both. Both species seem to be equally prevalent. Fungicide seed treatments gave variable control, but physical treatment with hot water or steam were more consistent and are recommended for neck rot.

Most UK carrots for winter/spring use are stored in situ in the field, covered with a thick layer of straw insulation. The sustainability of this system is becoming increasing challenged, so the AHDB have commission Plant Health Solutions in collaboration with Vegetable Consultancy Services to investigate potential alternatives that were identified in a previous desk study.

HDC is funding Plant Health Solutions to investigate seed-borne neck rot in onions. Neck rot can cause significant losses in stored onions. It is mainly caused by two species of Botrytis: B. aclada, B. allii; that were previously lumped together as one species (B. allii). The project aims to provide some insight into the relative importance of the two main species that cause it.

Bacterial canker is a destructive disease of plums and cherries, caused by two distinct pathovars of Pseudomonas syringae: pv. morsprunorum (Psm) and pv. syringae (Pss). Psm is host specific to Prunus spp., whereas Pss has a much wider host range. HDC has commissioned Plant Health Solutions to carry out further work to improved control of this disease in fruit production (TF 217), capitalising on the information and experience gained during a previous project that focussed on nursery production: HNS 179
Bacterial canker of stone fruit - New factsheet
07 Feb 2014
Bacterial canker is a destructive disease of cherries and plums, potentially killing trees. It is caused by two distinct pathovars of Pseudomonas syringae: pv. morsprunorum and pv. syringae. We have produced a new factsheet targeted at its management in the nursery situation that has recently been published by the HDC.
