Summary: Allium white rot, caused by Sclerotium cepivorum, can cause severe crop losses in UK bulb and salad onion crops. S. cepivorum resting bodies (sclerotia), which can survive 20 years, have built-up in fields due to intensive repeat cropping, particularly in many of the fen and silt soils most suitable for Allium crops.
Aims and Objectives:
2. To identify from the review the most feasible and promising control treatments for management of Allium white rot in the UK and their cost of application;
3. To determine the efficacy of selected disease management treatments in controlling Allium white rot in pot trials and in the field, alone and in combination;
4. To propose an integrated crop management strategy for Allium white rot based on the literature review and project results;
5. To communicate results to growers through reports, a factsheet, articles in AHDB Grower and growers meetings.
The work will cover both conventionally and organically grown bulb and salad onion crops as appropriate.
