Abstract
A process for the protection of cultivated plants against harmful effects of aggressive agricultural chemicals by the use of compounds of the formula I ##STR1## wherein R.sub.1, R.sub.2 and R.sub.3 independently of one another are each hydrogen, halogen, C.sub.1 -C.sub.3 -alkyl, C.sub.1 -C.sub.3 -alkoxy, nitro or cyano, R.sub.4, R.sub.5 and R.sub.6 independently of one another are each hydrogen, halogen or C.sub.1 -C.sub.3 -alkyl, A is any one of the groups --CH.sub.2 --, --CH.sub.2 --CH.sub.2 -- or --CH(CH.sub.3)--, and Z is cyano, or amidoxime which can be acylated on the oxygen atom, including acid addition salts and metal complexes thereof.

A compound of the formula ##STR194## wherein R.sub.1 ', R.sub.2 ' and R.sub.3 ' independently of one another are each hydrogen, halogen, C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.3 alkoxy, nitro or cyano,
- R.sub.4 ', R.sub.5 ' and R.sub.6 ' independently of one another are each hydrogen, halogen or C.sub.1 -C.sub.3 alkyl,
- A' is any one of the groups --CH.sub.2 --, --CH.sub.2 CH.sub.2 -- or --CH(CH.sub.3)--, and
- Z' is cyano
- including agriculturally acceptable the acid addition salts and metal complexes thereof,
- with the proviso that R.sub.1 ', R.sub.2 ', R.sub.4 ', R.sub.5 ' and R.sub.6 ' are not simultaneously hydrogen when R.sub.3 ' is hydrogen or chlorine and A' is --CH.sub.2 -- or --CH(CH.sub.3)--.
