SUMMARY Field tests were made of the four chlorinated hydrocarbon insecticides, aldrin, dieldrin, endrin and telodrin, applied as pre‐planting root dips with a methyl cellulose sticker. None of the treatments controlled the disease as effectively as a root dip in a 10% suspension of pure calomel, but they generally caused less initial growth check, resulting in some instances in significantly higher yields at maturity. Evidence that dieldrin and endrin had greater activity against clubroot than aldrin and telodrin was obtained in glasshouse experiments. This was confirmed in laboratory tests where it was also shown that the first two chemicals either eliminated or markedly reduced root hair infection of cabbage seedlings at a concentration as low as 0.1 p.p.m.
