Sclerotinia rot

Sclerotinia rot is the most major disease of carrots in store.

Identifying Features
A white woolly mould covers and soon destroys the roots. Occasionally it attacks the growing crop. Lower leaf stalks and crown turn black.

Treatment
None. If attacks are seen in the garden, water healthy plants with Cheshunt Compound after removing diseased plants immediately.

Prevention
Keep weeds under control. Store only sound roots in a dry, airy place. Do no grow carrots, parsnips or celery on land affected by sclerotinia rot in the past 2 seasons.
