This article discusses several treatments that aim to control club root of swedes by fungicidal seed pelleting. In trials at Wolverhampton and in Herefordshire, England in 1959 and 1960, zineb, ferbam, ziram and thiram gave no significant control of club root of swedes when used as seed pelleting. Calomel seed treatment gave some control, but the results with this material were variable and unreliable under conditions favouring high levels of infection. It is possible that seed pelleting might be more effective if means could be found of applying higher dosages of the materials to the seeds, but the use of known commercial resistant varieties of swede appears so far to be a better method of combatting club root than the use of chemical seed dressings.
