A method for modulating pest infestation and/or phytopathogenic infection in a plant comprising the steps of:

• (a) applying to the plant and/or seeds and/or substrate used for growing said plant an effective amount of a pesticidal composition comprising Muscodor albus strain SA-13 (NRRL Accession No. B-50774) fermentation, wherein said strain produces volatile compounds comprising 3-octanone, (−) aristolene, acetic acid 2-methylpropyl ester, propanoic acid 2-methyl-methyl ester, and propanoic acid 2-methyl-butyl ester;
• and
• (b) growing said plant and/or seeds;
• wherein said pest comprises Meloidogyne spp., and wherein said phytopathogenic infection comprises Fusarium spp., Pythium spp. and/or Rhizoctonia spp.
