Abstract


The experiment was conducted to check the effects of biochar and different priming agents on whitefly transmitted tomato leaf curl virus. Biochar was applied to potting mixture at 1%, 2% and 3% concentration. In order to check the effects of priming, tomato seedlings were primed with NaCl, glycerine and distilled water at three concentrations. After biochar application 22.43% disease severity was recorded that was significantly lower than control (40.12%). In graft inoculated plants, disease severity was in 15.32% while in control 50.23% disease severity was recorded. From primed seedling NaCl and glycerine shows good results then distilled water. In case of biochar, disease reduction was more at higher concentration (3%) than other two concentrations. Priming gave better results in case of whitefly inoculation.
