Martinomycin is a polyether antibiotic originally isolated from the actinomycete S. salvialis.1,2 It is active against a variety of bacteria, including 11 strains of S. aureus, three strains of S. pneumoniae, and E. faecalis (MICs = 0.12-0.5, 0.06, and 0.5 μg/ml, respectively).2 It induces mortality in 80% of third instar S. eridania larvae when applied at a concentration of 10 ppm to bean leaves.
