Monocerin is a fungal metabolite that has been found in F. larvarum and has diverse biological activities.1,2,3 It is active against the bacteria E. coli and B. megaterium, the phytopathogenic fungus M. violaceum, and the alga C. fusca in an agar diffusion assay when used at a concentration of 50 µg/disc.1 Monocerin (17.5 µg/ml) induces mortality in adult C. erythrocephala.2 It reduces root elongation in pre-germinated S. halepense seeds when used at a concentration of 33 ppm.3
