ABSTRACT:
Cyclobutanecarboxylic acid imides of the formula I ##STR1## wherein one of R.sub.1 and R.sub.6 is hydrogen, methyl or ethyl, and the other is methyl or ethyl, R.sub.2 and R.sub.3 independently of one another are each hydrogen, fluorine or methyl, or R.sub.2 is acetoxy or chlorine while R.sub.3 is hydrogen, and wherein R.sub.4 is hydrogen, methyl or chlorine, and R.sub.5 is hydrogen or methyl, whereby R.sub.3 and R.sub.4 together can also form an additional bond in the four-membered ring, are suitable for combating various fungi and have a particularly excellent action against Botrytis. They can be produced in an especially advantageous manner by photochemical [2+2] cycloaddition of alkenes or alkynes with for example appropriately substituted maleic acid-(3,5-dichlorophenyl)imides.
