Biological properties of flutianil as a novel fungicide against powdery mildew.

Flutianil, chemically characterized as a cyano-methylene thiazolidine, showed antifungal activity against powdery mildew on various crops but not any other plant pathogens tested. Flutianil showed high residual and translaminar activities and rainfastness against . It also exhibited curative activity against on cucumber at an extremely low concentration of 10 mg/L.

Synthesis and biological activity of a novel fungicide, flutianil.

Flutianil was discovered as a novel fungicide chemically characterized as a cyano-methylene thiazolidine. This chemical showed particularly high fungicidal activities against powdery mildew on various crops. Optimization of the fungicidal performance of the series of synthesized chemicals finally led to the identification of flutianil, which could control powdery mildew diseases.
