摘要

A compound having the structural formula IMAGE where R and R1 are the same or different and are hydrogen or C1-C6 alkyl; R2 is hydrogen, chlorine or bromine; R3 is hydrogen, C1-C6 alkyl, C1-C6 alkoxy, halogen, trihalomethyl, nitro, cyano, phenyl, phenyl subsituted with C1-C4 alkyl, C1-C4 alkoxy, halogen, trihalomethyl, nitro or cyano, phenoxy or phenoxy subsituted with C1-C4 alkyl, C1-C4 alkoxy, halogen, trihalomethyl, nitro or cyano; and n is 0 or 1 is disclosed. A composition which comprises a fungicidally effective amount of the compound and a carrier therefor is also set forth. In addition, a process for controlling phytopathogenic fungi wherein a fungicidally effective amount of the compound is applied to the locus to be protected is described.
