was analyzed in situ using a desorption electrospray ionization-mass spectrometry imaging (DESI-MSI) workflow. This approach interrogated the spatially oriented biochemical interactions that may serve as the molecular foundation for the effectiveness of these biological control agents in crop protection, identifying seven unique phenotypic regions within the dual culture. Herein, we demonstrate the benefits of biological control agent application in tomato cultivation and showcase the strengths of desorption electrospray ionization-mass spectrometry imaging when applied to the spatially resolved molecular characterization of agriculturally relevant microorganisms.
