Clubroot Resistant Varieties of Brassicas

Once you have clubroot in your soil you are stuck with it and very unlikely to ever be clubroot free but you can continue to grow brassicas successfully with club root resistant varieties.

Root Resistant Brassicas - Cauliflower Clapton from Thompson & MorganOver the last years the number of chemicals available to the gardener seems to do nothing but fall. Partially this is due to the enormous cost of putting chemicals through the tests required by the EU which has killed the small chemical suppliers to the garden market and greater knowledge of the risks and damage that chemicals can cause.

The days of indiscriminately spraying DDT around and using arsenic and mercury in the garden are long gone, but still within living memory!

Luckily for us gardeners and I suppose for the environment, the plant breeders have made some remarkable breakthroughs in producing varieties that are resistant to disease. Incidentally, these are produced with conventional techniques, not genetic modification.

Clubroot is one disease where there is no approved chemical control for the gardener and whilst it is possible to grow brassicas on clubroot infected land it’s not as easy as growing clubroot resistant varieties of brassica.

Club Root Resistant Swede Invitation

Club Root Resistant SwedeA breeding breakthrough, Invitation is a strong-growing, Clubroot resistant variety which also benefits from Powdery Mildew resistance and improved winter hardiness over other varieties.
