Inhibitory effect of virazole (ribavirin) on the replication of tomato white necrosis virus (VNBT).
Tomato plants (Lycopersicon esculentum Mill.) inoculated with tomato white necrosis virus (VNBT) and treated with Virazole (1-beta-D-ribofuranosyl--1, 2, 4-triazole-3-carboxamide) at a concentration of 500 mg/l developed systemic virus symptoms in only 40 per cent of the plants in which a remarkable reduction in virus concentration was also observed. From inoculated and Virazole-treated plants which had produced no symptoms, no virus could be recovered. This result suggests that Virazole may inhibit replication of VNBT in tomato.
