- wherein R1 and R2 independently of one another each represent hydrogen, halogen, nitro, cyano, or represent in each case an optionally substituted alkyl, alkenyl, alkinyl or aryl.
A microbicidal composition comprising:
- (A) a compound of the formula (I)
- 10
- wherein R1 and R2 independently of one another each represent hydrogen, halogen, nitro, cyano, or represent in each case an optionally substituted alkyl, alkenyl, alkinyl or aryl,
- (B) solvents or diluents and,
- (C) optionally processing auxiliaries, or active compounds, or mixtures thereof.
