Triazole compounds useful as plant growth regulators of the formula ##STR1## and stereoisomers thereof, wherein R.sup.1 is selected from alkyl and haloalkyl groups, R.sup.2 is hydrogen, and R.sup.3 is a tertiary butyl group optionally substituted by halogen; and acid addition salts, and metal complexes thereof.

Triazolylmethyl tert-butyl carbinol derivatives which have plant growth

A triazole derivative having the general formula (I): ##STR1## and stereoisomers thereof, wherein R.sup.1 is an alkyl group containing from 3 to 6 carbon atoms, or a haloalkyl group containing from 2 to 5 carbon atoms, or a group --CH.sub.2 --Z where in Z is a cycloalkyl group containing from 3 to 5 carbon atoms, R.sup.1 containing primary or secondary carbon atoms only; R.sup.2 is hydrogen or an alkyl group containing from 1 to 4 carbon atoms; and R.sup.3 is a tertiary butyl group optionally substituted by halogen; and salts, esters and metal complexes of the compound of formula (I) wherein R.sup.2 is hydrogen. These compounds are useful as plant growth regulating agents.

Heterocyclic compounds

Compounds having the general formula (I): ##STR1## and stereoisomers thereof, wherein R.sup.1 and R.sup.2 are each hydrogen, a cation, alkyl, cycloalkyl, aryl or aralkyl optionally substituted with halogen, nitro, alkyl, haloalkyl, alkoxy, haloalkoxy, phenyl, phenoxy, halophenyl or halophenoxy, or together form a ring; R.sup.3 and R.sup.4 are each hydrogen, alkyl, cycloalkyl, heterocyclyl, aryl or aralkyl optionally substituted with halogen, nitro, alkyl, haloalkyl, alkoxy, haloalkoxy, phenyl, phenoxy, halophenyl or halophenoxy; W is N or CH; X is oxygen or sulphur; ester and ether derivatives of the alcohol; and its acid addition salts and metal complexes. The compounds are useful as fungicides and for plant growth regulation.

Azolylalkyl phosphonic acid herbicides

Compounds useful as plant growth regulators and fungicides and having the formula ##STR1## and stereoisomers thereof, wherein W is --CH.dbd. or .dbd.N--; Q is optionally substituted aryl, especially optionally substituted phenyl, or optionally substituted aralkyl or alkyl; R.sup.1, R.sup.2, R.sup.3, R.sup.4, R.sup.5 and R.sup.6, which may be the same or different, are H, optionally substituted alkyl, cycloalkyl, aralkyl or phenyl; R.sup.7 and R.sup.8 are H, alkyl or optionally substituted phenyl; and acid addition salts and metal complexes thereof, and processes and intermediates for their preparation.
