520			_aWhite root disease caused by Rigidoporus microporus (Fr) Overeem is the most serious disease of Hevea in Sri Lanka. The most effective method of controlling the disease is by adopting cultural practices recommended by the Rubber Research Institute of Sri Lanka, prior to replanting. The chemical treatment procedure is quite effective if the diseased trees are detected at an early stage. However the conventional collar protectant treatment is very tedious and labour intensive. Therefore to overcome this fungicide drenching method was tested. Although the fungicides, Bayleton (triadimefon), Bayfidan (triadimenol), Folicur (tebuconazole) and Contaf (hexaconazole) are equally effective in controlling the disease, when the cost involved are considered, it is not economical to use Bayleton and Bayfidan. Therefore the fungicides, Folicur (tebuconazole) and Contaf (hexaconazole) can be useed effectively and economically to reduce the white root disease incidence in young rubber plantations.
