Fungicidal active compound combinations

DETAILED DESCRIPTION We claim: 1.
A fungicidal composition comprising synergistic effective amounts of a valinamide derivative of the formula (I): ##STR26## in which R.
sup.
1 represents i-propyl or s-butyl; and R.
sup.
2 represents chlorine, methyl, ethyl or methoxy; and at least one component selected from the group consisting of: (A) dichlofluanid of the formula (II): ##STR27## and (B) tolylfluanid of the formula (III) ##STR28## 2.
A method of combatting fungi which comprises applying to such fungi or to a fungus habitat a synergistic fungicidal effective amount of a composition according to claim 1.




Description:
The present application relates to new active compound combinations composed of, on the one hand, valinamide derivatives and, on the other hand, of other, known fungicidal active compounds, and which are highly suitable for combating phytopathogenic fungi.
It is already known that valinamide derivatives has fungicidal properties (cf.
EP-A 472,996).
The activity of this substance is good; however, it leaves something to be desired in some cases when low application rates are used.
Furthermore, it is already known that a large number of azole derivatives, aromatic carboxylic acid derivatives, morpholine compounds and other heterocycles can be employed for combating fungi (cf.

Buchel "Pflanzenschutz und Schadlingsbekampfung" ?Crop Protection and Pest Control! pages 87, 136, 140, 141 and 146 to 153, Georg Thieme Verlag, Stuttgart 1977).
However, the activity of the substances in question is not always satisfactory when low application rates are used.
It has now been found that the new active compound combinations of valinamide derivatives of the general formula (I) ##STR2## in which R.
sup.
1 represents i-propyl or s-butyl and R.
sup.
2 represents chlorine, methyl, ethyl or methoxy, and (A) dichlofluanid, of the formula ##STR3## and/or (B) tolylfluanid, of the formula ##STR4## and/or (C) tetrachloro-isophthalo-nitrile of the formula ##STR5## and/or (D) propineb, of the formula ##STR6## and/or (E) tetramethyl-thiuram-disulphide, of the formula ##STR7## and/or (F) mancozeb, of the formula ##STR8## and/or (G) dyrene, of the formula ##STR9## and/or (H) copper oxychloride and/or (I) captan of the formula ##STR10## and/or (K) a morpholine derivative of the formula ##STR11## and/or (L) dithianon, of the formula ##STR12## and/or (M) Phaltan, of the formula ##STR13## and/or (N) cymoxanil, of the formula ##STR14## and/or (O) propamocarb, of the formula (CH
