Abstract:
The present investigation was conducted in Kharif 2018 in the Rice research farm of Birsa Agricultural University, Ranchi, Jharkhand to study the management of leaf folder through use of HPR (host plant resistance) and insecticidal application. The experimental findings revealed that use of host plant resistance coupled with judicious application of newer molecule of insecticide i.e. flubendiamide 480 SC @ 50 ml/ha sprayed at 30, 50 and 80 DAT could be found highly effective in substantial reduction in the incidence of leaf folder which in turn realized appreciable enhancement in additional yield over the untreated control in all the five varieties of rice amounting to 20.0, 16.10, 14.00, 11.22 and 10.10 q/ha in case of Lalat, IR-64 (drt-1), Sahbhagi Dhan, BVS- 1, TN-1, respectively.
