Antiviral action of Harpulia Cupanioides and Mirabilis Jalapa against tomato spotted wilt virus (TSWV) infecting tomato

摘要: Mirabilis jalapa and Harpulia cupanioides remain as an unexploited potential to be tapped, sources of antiviral principles. The protein from M. (MAP) H. (HAP) were highly effective in inhibiting TSWV at 60 80% saturation. A minimum concentration 400 μg/ml MAP was sufficient inhibit TSWV. HAP 800 recorded 98.41% inhibition lesion formation. plants treated with challenged did not show significant variation absorbance values when compared uninoculated healthy plants, indicating the absence detectable virus through indirect DAS ELISA thus effectiveness AVPs. Pre-application induced activity phenols, PO, PPO PAL leading suppression on local systemic host.
