Descrição: dc.descriptionDissolution in water of volatile organic compounds (VOCs) emitted by microorganisms may explain, in part, the distribution of VOCs throughout the soil, and thus the process of exposure of plant-parasitic nematodes (PPN) to these molecules. Water was exposed for short periods (0.5–24 h) to the VOCs emitted by Fusarium oxysporum strain 21 (Fo-21). Water exposed to VOCs caused 100% immobility in second-stage juveniles (J2) of Meloidogyne incognita. In addition, inoculation of J2 in tomato decreased infectivity up to 70% and reproduction up to 65%. Application of water exposed to VOCs in substrate infested with M. incognita J2 resulted in a 56% reduction in number of galls and a 49% reduction in the number of eggs. This is the first in vivo experimental demonstration of the toxicity of water exposed to fungal VOCs to a PPN. Gas chromatography–mass spectrometry analysis of the volatiles led to the identification of 28 compounds in the water exposed to the VOCs of Fo-21, and 36 compounds in the emission of fungus. The main classes of compounds emitted by Fo-21 were sesquiterpenes, esters and alcohols. This is the first evaluation of volatile compounds retained in water exposed to fungal VOCs, and which are toxic to a PPN.-
