This study explored whether satellite remote sensing can estimate black truffle mycelium biomass. Optical vegetation indices showed limited results, while Sentinel-1 radar backscatter had significant correlations, especially in spring. Findings suggest radar data capture soil moisture dynamics linked to fungal activity, offering a promising tool for sustainable truffle orchard management.

This research investigates Trichoderma fungi as a biological control against Armillaria honey fungus, a major plant pathogen with no effective treatment. Forty Trichoderma strains were tested; seven reduced disease in plants and one prevented infection entirely. These findings suggest plants could be inoculated like a “vaccination” to protect forests, crops, and gardens.
