Characterization of Antifungal Volatile Compounds Evolved from Solarized Soil Amended with Cabbage Residues

Abstract

The objectives of this study were to characterize volatile compounds evolved from solarized soil amended with cabbage residues and to assess the effect of these volatile compounds on soilborne fungi. Quantitative and qualitative differences in volatile compounds from heated and nonheated cabbage-amended soil were found. Heated cabbage-amended soil generated a wide range of volatile compounds, including alcohols, aldehydes, sulfides, and isothiocyanates. The levels of isothiocyanates and aldehydes generated in heated soil were significantly correlated with reduced propagule numbers of Pythium ultimum and Sclerorium rolfsii during exposure [...]
