Abstract
The present invention relates to the use of new and known maleimide salts for controlling phytopathogenic fungi, and also to methods for controlling phytopathogenic fungi in crop protection, in the household and hygiene sectors and in materials protection, and also to crop protection compositions comprising these maleimide salts.
