Active Compound Combinations
The present invention relates to active compound combinations, in particular within a fungicide composition, which comprises (A) a dithiino-tetracarboximide of formula (I) and a metal salt (B). Moreover, the invention relates to a method for curatively or preventively controlling the phytopathogenic fungi of plants or crops, to the use of a combination according to the invention for the treatment of seed, to a method for protecting a seed and not at least to the treated seed. In particular the combinations according to the invention are useful to obtain plants with greener leaf color.
