DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a fungicidal mixture which comprises (2RS,3SR)-1-[3-(2-chlorophenyl)-2,3-epoxy-2-(4-fluorphenyl)propyl]-1H-1,2, 4-triazole ##STR3## or a salt or adduct thereof, and b) tetrachloroisophthalonitrile II ##STR4## in a synergistically active amount.
The invention furthermore relates to methods of controlling harmful fungi using mixtures of the compounds I and II and to the use of compound I and of the compound II for the preparation of such mixtures.
The compound of the formula I, its preparation and its action against harmful fungi are disclosed in EP-A 196 038 and "The Pesticide Manual", 10th Edition, The British Crop Protection Council and The Royal Society of Chemistry, 1994--termed "Pesticide Manual" hereinbelow--Page 67: BAS 480 F, proposed common name: epoxiconazole). The compound II (common name: chlorothalonil), its preparation and its action against harmful fungi is also known (cf. "Pesticide Manual", Page 193).
With a view to reducing the rate of application and to improving the spectrum of action of the known compounds I and II, it is an object of the present invention to provide mixtures which have an improved activity against harmful fungi while the total amount of active ingredients applied is reduced (synergistic mixtures).
Accordingly, we have found that this object is achieved by the mixture defined at the outset. Moreover, we have found that better control of the harmful fungi is possible by applying compound I and compound II simultaneously, together or separately, or by applying compound I and compound II in succession than when the individual compounds are used alone.
Due to the basic character of the 1,2,4-triazole ring group, the compound I is capable of forming salts or adducts with inorganic or organic acids or with metal ions.
Examples of inorganic acids are hydrohalic acids such as hydrofluoric acid, hydrochloric acid, hydrobromic acid and hydriodic acid, furthermore carbonic acid, sulfuric acid, phosphoric acid and nitric acid.
Suitable organic acids are, for example: formic acid and alkanoic acids, such as acetic acid, trifluoroacetic acid, trichloroacetic acid and propionic acid, and also glycolic acid, thiocyanic acid, lactic acid, succinic acid, citric acid, benzoic acid, cinnamic acid, oxalic acid, alkylsulfonic acids (sulfonic acids having straight-chain or branched alkyl radicals having 1 to 20 carbon atoms), arylsulfonic acids or aryldisulfonic acids (aromatic radicals such as phenyl and naphthyl which have attached to them one or two sulfo groups), alkylphosphonic acids (phosphonic acids having straight-chain or branched alkyl radicals of 1 to 20 carbon atoms), arylphosphonic acids or aryldiphosphonic acids (aromatic radicals such as phenyl and naphthyl which have attached to them one or two phosphoric acid radicals), it being possible for the alkyl or aryl radicals to have attached to them further substituents, eg. p-toluenesulfonic acid, salicylic acid, p-aminosalicylic acid, 2-phenoxybenzoic acid, 2-acetoxybenzoic acid etc.
Suitable metal ions are, in particular, the ions of the elements of the first to eighth sub-group, mainly chromium, manganese, iron, cobalt, nickel, copper, zinc, and also of the second main group, mainly calcium and magnesium, of the third and fourth main groups, in particular aluminum, tin and lead. The metals can exist in the various valencies which they can assume.
When preparing the mixtures, it is preferred to employ the pure active ingredients I and II, with which further active ingredients against harmful fungi or other pests such as insects, arachnids or nematodes, or else herbicidal or growth-regulating active ingredients, or fertilizers, can be admixed, if so required.
The mixtures of the compounds I and II, or the simultaneous joint or separate use of the compounds I and II, have an outstanding action against a wide spectrum of phytopathogenic fungi, in particular from the classes of the Ascomycetes, Basidiomycetes, Phycomycetes and Deuteromycetes. Some of them act systemically and can therefore also be emp
