Abstract

The botanicals (Azadirachta indica, Clerodendrum aculeatum and Terminalia arjuna) tested, against infection of cucumber mosaic virus, were found most effective in reducing disease, severity and enhancing yields. Minimum disease incidence (22.21 and 22.16 %) with maximum vine length (5.20 and 5.4 m), secondary branches (63.80 and 64.70), early flowering (44.0 and 43.10 DAS), number of fruit/plant (18.75 and 18.30) and maximum yield (13.40 and 14.20 kg per plot) was recorded in seed treatment with neem extract followed by six sprays of the same botanical on host plant during 2004–05 and 2005–06.Yield loss estimated was 2.23 to 47.31% during 2004–05 and 2.81 to 48.60% during 2005–06.
