Everything about Clubroot totally explained
Clubroot is a disease of
cabbages,
radishes,
turnips, and other plants belonging to the family
Cruciferae (
mustard family). It is caused by
Plasmodiophora brassicae, what was once considered a
slime mold but is now put in the group
Phytomyxea. It has as many as nine races.
Gall formation takes place on latent roots and gives the shape of a club or
spindle. In the cabbage such attacks on the roots cause undeveloped heads or a failure to head at all. It is an important disease, affecting an estimated 10% of the total cultured area world-wide.
Historical reports of clubroot date back to the
13th century in Europe. In the late
19th century, a severe epidemic of clubroot destroyed large proportions of the cabbage crop in
St. Petersburg. The Russian scientist
Mikhail Woronin eventually identified the cause of clubroot as a "plasmodiophorous organism" in
1875, and gave it the name
Plasmodiophora brassicae.
In 18th, 19th and early 20th century Britain clubroot was sometimes called
finger and toe,
fingers and toes,
anbury, or
ambury, these last two also meaning a soft tumor on a horse.
The potential of cultural practices to reduce crop losses due to clubroot are limited, and chemical treatments to control the fungus are either banned due to environmental regulations or are not cost effective. Breeding of resistant cultivars therefore is a promising alternative.
