A compound for the control of mites and insects of the species Homoptera, of the formula ##STR15## wherein R.sup.1 is attached to the 1- or 2-position of the 1,2,4-triazole ring and is methyl, ethyl or C.sub.1-4 -haloalkyl;
- R.sup.2 is o-halophenyl, o,o'-dihalophenyl or o,p-dihalophenyl, which halogen atoms are selected from the group consisting of fluorine, chlorine, bromine and iodine atoms;
- or phenyl which is substituted in the ortho position with a methyl, trifluoromethyl, methoxy or cyano group;
- and
- R.sup.3 is o-trifluoromethyl-phenyl, or an acid addition salt of such a compound.
A composition for the control of mites and insects of the species Homoptera comprising an effective amount of at least one compound of the formula ##STR16## wherein R.sup.1 is attached to the 1- or 2-position of the 1,2,4-triazole ring and is methyl, ethyl or C.sub.1-4 -haloalkyl;
- R.sup.2 is o-halophenyl, o,o'-dihalophenyl or o,p-dihalophenyl, which halogen atoms are selected from the group consisting of fluorine, chlorine, bromine and iodine atoms;
- or phenyl which is substituted in the ortho position with a methyl, trifluoromethyl, methoxy or cyano group;
- and
