What is "farinomalein"

Farinomalein is a natural maleimide with formula CHNO - was first isolated from the entomopathogenic fungus Isaria farinosa (Paecilomyces farinosus) - source H599 (Japan).

Farinomalein has shown potent and selective inhibition (0.15-5 μg/disk) against eight isolates of plant pathogenic Phytophthora sojae. These results suggest that farinomalein might be useful as a candidate pesticide for the treatment of Phytophthora stem rot in soybean.
