The infectivity of TMV recovered by dialysis from incubation with anthraquinone glycosides in vitro has been reduced in contrast to infectivity of TMV control, it seems that anthraquinone glycosides have direct viricidal effect on TMV. The anthraquinone glycosides may interfere recognization of TMV to host receptor when applied before TMV inoculation. The anthraquinone glycosides can inhibit multiplication of TMV in infected leaf discs but did not inhibit infectivity of TMV-RNA in vitro. The control of tobacco mosaic virus disease of N.
