Fusarium species


In Daffodils it appears as a brown discoloration at the base of the bulb where roots emerge. It spreads up the scale leaves surrounding the bulb and occasionally pink fungal growth can be seen when the scales are peeled back. On planting, the bulbs rot in the ground or may produce a few straggly yellow shoots. The bulbs may also rot in storage if the temperature is too high.

Don't plant Daffodils on infected areas for five years or fumigate the soil.
Lift bulbs each year, remove outer scales and dip in fungicide as soon as leaves go naturally yellow.
Keep bulb storage areas cool and store bulbs in wire baskets or well-ventilated situations.
