Abstract

Derived macrocyclic compounds of the formula I ##STR1## where R is hydrogen, methyl or certain acyl groups, the dotted line in the 9,10-position is a saturated bond or, in the event that R is methyl, is also a double bond, and X is a keto group, or a substituted or unsubstituted oxime, hydrazone or semicarbazone, represent effective microbicides for controlling plant diseases. They can be employed in the customary formulation as agrochemical agents.
