The incidence and the severity of CLFD are on the increase in many rubber growing countries.Under nursery condition,almost all clones are seriously affected by the disease.Therefore,the management of CLFD in the nurseries is vital as quality of the planting materials directly influences productivity.The Rubber Research Institute of Sri Lanka recommends the prophylactic application of fungicides to protect nursery plants from CLFD.In this investigation the efficiency of several systemic fungicides and fungicide mixtures against CLFD in nurseries was evaluated.Furthermore effects of modifications to cultural practices were also evaluated in combination with the fungicide treatments.
