A pot culture experiment was undertaken during kharif, 2017 on evaluation of induced mechanism of zinc in rice for expression of tolerance against white backed plant hopper (WBPH) in the Department of Entomology, College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar. It was revealed that basal application of Zn EDTA @ 40 kg/ha along with its foliar spray @ , twice at 30 and 45 days after transplanting (DAT) (T6) expressed fair degree of tolerance against WBPH. Zinc application delayed the wilting in treated plants as compared to control under high pest load. The functional plant loss index and per cent loss in grain and straw weight were also minimum in zinc treated plants comprising basal and foliar application as compared to sole application and control. | Induced tolerance mechanism of resistance in rice to white backed plant hopper through zinc application
