Description:

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.

Clover

Plant tolerant varieties. See Disease Susceptibility of Clover Varieties.

Daffodils

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.

Don't use excessive quantities on nitrogenous fertiliser.

The disease may be spread by hot water treatment used for nematode control so treat with fungicide after the bulbs cool down.

Gladiolus

Keep bulb storage areas cool.

Dip corms or cormlets in fungicide.

Passionfruit

Avoid damage to base of stem by cultivation or fertilisers

Strawberries

Plant runners that are certified as disease free.
