Abstract
Aqueous leaf extract ofChenopodium ambrosoides prevented infection of tobacco mosaic and sunnhemp rosette viruses when applied to the leaves by increasing the resistance of the host plants. The leaf extract, however, did not inhibit lesion production inC. amaranticolor. The leaf extract induced only localized resistance in many hypersensitive hosts. Lesion production was considerably decreased when the leaf extract was applied to the under surface of leaves and virus challenge inoculated on the upper surface. The inhibitory activity of the leaf extract was reversed by simultaneous application of metabolic inhibitor, Actinomycin-D. The leaf extract was active both at acidic and basic pH.
