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.

Carrot field storage

01 Sep 2015

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.

Onion neck rot: seed infection, pathogens and treatments

01 Feb 2015

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. Find out more


New HDC Bacterial Canker Project

01 May 2014

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 Find out more


Bacterial canker of stone fruit - New factsheet
