there a cure for club root other than liming or leaving the soil
for five or so years?
of the Cruciferae family is attacked by club root. This includes
brassica, stocks, allysum and wallflowers. Roots become swollen,
causing a stunting of growth, and leaves turn yellow and wilt.
It is best not to plant
brassicas into soil that has grown infected plants previously. Rotate
crops to avoid disease build-up in the soil, and ensure that the
soil is well drained.
Adding lime is definitely
an advantage, but you can also dip the roots of seedling transplants
in a suitable fungicide solution before setting them out.
Unfortunately there is
no cure for infected plants, which should be burned or placed in
the rubbish bin.
