The inhibitory effect of benzyl-dimethyl-hexadecylammoniumchloride (BDHA) and N-benzyl-N-dodecyl-N-bis (2-hydroxyethyl)-ammoniumchloride (BDBA) to various phytopathogenic viruses was studied. These substances were selected from 10 other quaternary ammonium compounds tested. They showed an inhibitory activity against BMV-, CMV-, CMoV-, PVX-, TMV- and TNV-infectio Studies on the mode of action of BDBA and BDHA in the virus-host-system TMV/Nicotiana tabacum var. Xanthi nc. revealed that the compounds exhibited besides a pre-infectional also a post-infectional inhibitory activity. Further, it has been shown that they display a direct inhibitory effect on TMV. The longlasting pre-infectional effect of the compounds resulted not only in a reduction of formation of local lesions, but also in a smaller size and a lower antigene content of the lesions. An antiviral activity was also detected in non-treated younger leaves of treated plants 10-14 days after treatment. This phenomenon was linked with the appearance of some new proteins in the intercellular fluids
