Antiviral Factors in Soil¹

ABSTRACT

Tobacco mosaic virus (TMV) is a very stable virus in vitro. When incorporated into soil, its infectivity or recoverability gradually disappeared. The rate of TMV degradation in soil was a function of temperature, faster at 25°C than at either 5 or 40°C. It degraded faster in relatively moist soil than in drier soil, but in a separate experiment was quite stable in flooded soil. When the pH of an active antiviral soil was adjusted from 7 to 4.9 its antiviral activity was greatly reduced. TMV remained relatively stable in autoclaved soil or soils containing added streptomycin sulfate or cycloheximide, but not with added benlate (Benomyl) fungicide [methyl, 1 (butylcarbamoyl)-2-benzimidazole carbamate]. Physical forces such as desiccation and aeration by bubbling damaged TMV particles. Soil collected from different locations in southern California were classified as highly active, active, and slightly active in degrading TMV.
