Abstract
Compounds of Formula I are disclosed which are useful as fungicides wherein X is —O—, —CH(R11)— or ═C(R11)—; R1 is H or C1-C2 alkyl; R2 is H; C1-C6 alkyl; C3-C6 cycloalkyl; or phenyl optionally substituted with halogen, cyano, C1-C2 alkyl or C1-C2 alkoxy; and R3-R11 are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula I and a method for controlling plant diseases caused by fungal plant pathogens which involves applying an effective amount of a compound of Formula I.
