Abstract

Novel macrocyclic compounds of the formual I ##STR1## where the dotted line in the 9,10-position is a saturated bond or a double bond, alternatively, and R is hydrogen, methyl or certain acyl radicals, and R.sub.o is hydrogen, halogen, azido, thiol, hydroxyl or --OY, where Y is, among other radicals, an ether radical, a silyl group, a sulfonyl group, a sugar radical or a (thiol)acyl radical, and R being methyl if there is a double bond in the 9,10-position, have microbicidal properties for the control of phytopathogenic microorganisms. They can be employed in the customary formulation for the control of plant disease.
