Fungicidal composition contains a phytopathogenic fungicide (I) and at least one phosphonate or phosphinate derivative of formula (R1)(R2)P(=O)OR3 (II). R1 = 6-20C alkyl, 6-20C alkoxy or optionally substituted phenyl; R2 = benzyl, 6-20C alkyl (optionally interrupted by NH or O), di(6-20C alkyl)amino or a group CH2CH2P(=O)(R1)OR3 (a); and R3 = 6-20C alkyl. Also claimed are: (A) phosphinates (IIA) i.e. (II; R1 = 6-20C alkyl; R2 = phenyl); (B) phosphonates (IIB) i.e. (II; R1 = 6-20C alkoxy; R2 = (a; R1 = OR3)); and (C) dialkyl alkyl- or dialkyl-aminophosphonate derivatives of formula R3R5N-CH2(CH2)x-P(=O)(OR3)2 (II'); R5 = H or as R3; and x = 0-1. |
