Optically active fungicidal trifluoromethylalkylamino-triazolopyrimidines

摘要

The novel optically active compounds of formula I: (R<1>, Hal and L<1> through L<5> are defined in the specification) wherein the enantiomeric excess of the (S)-enantiomer is at least 70 %., show enhanced selective fungicidal activity. The new compounds are processed with carriers, and optionally with adjuvants, to form fungicidal compositions.
