Abstract:

Effect of dates of sowing on incidence leafhopper, Empoasca flavescens on castor genotypes during Kharif season 2013 revealed that incidence of leaf hoppers in general comparatively high in late sown crop than early sown crop. When castor was sown early, high hopper population was recorded on GCH-4 (98.67 hoppers) and low population on M-574 (9.00 hoppers). In the case of early sown crop, hopper burn score of 2 with 11 to 25 percent injury was observed on DPC-9, DCS-9, PCH-111, PCH-106 and Kranthi and where as in late sown crop, maximum hopper burn score of 4 with more than 50 percent hopper injury was observed on DPC-9, DCS-9, PCH-288, PCH-111, RG-2835, PCH-106, PCH-222 and RG-2928.
