Novel benzotriazolesulfonic acid derivatives of formula ##STR1## wherein: R.sub.1 is hydrogen, halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy having at least two identical or different halogen atoms, CF.sub.3, nitro or the group N(R')R", wherein R' and R" are each independently of the other C.sub.1 -C.sub.4 alkyl; R.sub.2 is phenoxy or phenylthio each of which is unsubstituted or mono- to tri-substituted by halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 haloalkoxy having at least two identical or different halogen atoms, cyano, nitro, C.sub.2 -C.sub.4 alkenyl, C.sub.2 -C.sub.4 alkynyl, phenyl, 2-phenylethynyl or by a further phenoxy radical that is unsubstituted or substituted by halogen, C.sub.1 -C.sub.4 alkyl and/or by C.sub.1 -C.sub.4 alkoxy; or R.sub.2 is the radical O--CH.sub.2 --O; R.sub.3 is alkyl, aryl or aralkyl having a maximum of 14 carbon atoms, these radicals can be substituted by halogen, C.sub.1 -C.sub.4 alkyl and/or by nitro; including the position isomers of R.sub.1 and R.sub.2, insofar as those substituents occupy positions 5 and 6. The novel compounds have plant-protecting properties and are suitable especially for protecting plants against attack by phytopathogenic microorganisms such as fungi, especially Oomycetes.
