Severely infected gardens were observed in Cumbum block, followed by that of moderate incidence in Uthamapalayam block. Incidence of the disease - at sporadic level - was seen in all other blocks (Chinnamanur, Bodinayakkanur, Theni, Periyakulam, Andipatti and Kadamalaikundu) of the district. Sporadic occurrence of RWD was recorded for the first time in a region (Ayyampalayam) of Dindigul District. Spindle leaf samples drawn from RWD affected palms from several locations of these districts reacted positively and strongly against the RWD antiserum. In RWD affected palms of these districts, leaf rot disease (LRD) was also found to be superimposed. Association of various species of fungi with LRD was identified. Reasons for the spread of RWD complex, remedial measures required etc. are highlighted.enArticle
