Preferably an amount of 50 to 500 g, in particular 100 to 250 g, of component a) and 500 to 5000 g, in particular 1000 to 3000 g copper, contained in component b) are used per hectare to be treated. The weight ratio of component a): copper, contained in component b), is preferably 1: 1 to 100, in particular 1: 2 to 50, for use in the process according to the invention, the weight ratio 1: 5 to 20 being particularly preferred.
35 Rostpilze, gegen welche das Verfahren der Erfindung besonders wirkungsvoll ist, umfassen diejenigen der Art Hemi-leia, bei Pflanzen wie Kaffee, z.B. Hemileia vastatrix, diejenigen der Art Puccinia, bei Pflanzen wie Getreide (z.B. Weizen, Gerste), z.B. Puccinia striiformis, oder bei Zierpflanzen, 40 z.B. Puccinia pelargoni! (bei Geranien) oder Puccinia antir-rhini (bei Löwenmaul), diejenigen der Art Melampsora bei Pflanzen wie Flachs, z.B. Melampsora lini, diejenigen der Art Phakopsora bei Pflanzen wie der Sojabohne, z.B. Pha-kopsora pachyshisi, und diejenigen der Art Uromyces auf 45 Pflanzen wie Bohnen, z.B. Uromyces appendiculatus. 35 rust fungi, against which the method of the invention is particularly effective, include those of the Hemi-leia species, in plants such as coffee, e.g. Hemileia vastatrix, those of the Puccinia species, in plants such as cereals (e.g. wheat, barley), e.g. Puccinia striiformis, or in ornamental plants, 40 e.g. Puccinia pelargoni! (in geraniums) or Puccinia antir-rhini (in snapdragon), those of the Melampsora species in plants such as flax, e.g. Melampsora lini, those of the Phakopsora species in plants such as soybean, e.g. Pha-kopsora pachyshisi, and those of the Uromyces species on 45 plants such as beans, e.g. Uromyces appendiculatus.
Die Komponenten werden vorzugsweise als Mischung in Form eines wässrigen Sprays oder eines Konzentrates auf Basis von Öl appliziert. The components are preferably applied as a mixture in the form of an aqueous spray or a concentrate based on oil.
Die Formulierungen können Tenside, wie Netzmittel und so Dispersionsmittel, enthalten, insbesondere die Formulierungen, die als wässriger Spray angewendet werden, wie wasserlösliche Konzentrate und benetzbare Pulver. The formulations can contain surfactants, such as wetting agents and so dispersing agents, in particular the formulations which are used as an aqueous spray, such as water-soluble concentrates and wettable powders.
Benetzbare Pulverformulierungen können z.B. erhalten werden durch Mischung der aktiven Komponenten mit ge-55 eigneten festen Trägern, beispielsweise Ton, wie Attapulgit oder Kaolin, Calciumcarbonat, Silica, zusammen mit Dispersions- und Netzmitteln und gewünschtenfalls Formulierungsbestandteilen, wie Antischaummittel. Wettable powder formulations can e.g. are obtained by mixing the active components with suitable solid carriers, for example clay, such as attapulgite or kaolin, calcium carbonate, silica, together with dispersing and wetting agents and, if desired, formulation constituents, such as anti-foaming agents.
Beispiele geeigneter Dispersions- und Netzmittel sind 6o z.B. Tenside, wie das Kondensationsprodukt von Formaldehyd mit Naftalensulfonat, Alkylarylsulfonate, Lignin-sulfonat und das Reaktionsprodukt eines Alfcylphenols mit Ethylenoxid. Examples of suitable dispersing and wetting agents are e.g. Surfactants such as the condensation product of formaldehyde with naftalenesulfonate, alkylarylsulfonates, lignin sulfonate and the reaction product of an alcylphenol with ethylene oxide.
Wasserlösliche Konzentrate (die sogenannten «flow-65 ables») können z.B. hergestellt werden durch Dispersion der vorgemahlenen aktiven Komponenten in Wasser, das Tenside, Frostschutzmittel, Verdickungsmittel und gewünschtenfalls Antischaummittel enthält. Water-soluble concentrates (the so-called "flow-65 ables") can e.g. are produced by dispersing the pre-ground active components in water, which contains surfactants, antifreeze, thickeners and, if desired, anti-foaming agents.
Beispiele geeigneter Tenside sind Ligninsulfonate, äth-oxylierte Alkylphenole, äthoxylierte ölige Alkohole, Phosphorsäureester von äthoxylierten Alkylphenolen oder von äthoxylierten öligen Alkoholen. Examples of suitable surfactants are lignin sulfonates, ethoxylated alkylphenols, ethoxylated oily alcohols, phosphoric acid esters of ethoxylated alkylphenols or of ethoxylated oily alcohols.
Beispiele geeigneter Frostschutzmittel sind z. B. Ethylen-glykol, Propylenglykol. Examples of suitable antifreeze are e.g. B. ethylene glycol, propylene glycol.
Geeignete Verdickungsmittel sind z. B. Xanthangummi, Methylencellulose, Hydroxyethylcellulose, Attapulgit, Hec-torit, chemisch modifizierte Montmorillonite, Bentonite. Suitable thickeners are e.g. B. xanthan gum, methylene cellulose, hydroxyethyl cellulose, attapulgite, hec-torite, chemically modified montmorillonite, bentonite.
Ein alternatives Verfahren zur Herstellung von Suspensionskonzentraten besteht darin, dass man zunächst einen Schlamm herstellt durch Mischung von Wasser mit Ten-siden, Verdickungsmitteln und gewünschtenfalls mit Frostschutzmitteln und Emulgatoren. Dieser Schlamm wird dann gemischt mit den aktiven Komponenten und anschliessend nassgemahlen mit Hilfe von z.B. einer Perlmühle, bis die Teilchengrösse 5 micron oder kleiner ist. An alternative method for the production of suspension concentrates is that a sludge is first produced by mixing water with surfactants, thickeners and, if desired, with antifreeze and emulsifiers. This sludge is then mixed with the active components and then wet-ground using e.g. a bead mill until the particle size is 5 microns or smaller.
Im allgemeinen enthalten die konzentrierten Formulierungsformen zwischen 1 und 90 Gewichtsprozenten der aktiven Komponenten gemäss der Erfindung, vorzugsweise zwischen 5 und 50 Gewichtsprozenten.

Das erfindungsgemässe Verfahren wird durch die folgende Prüfmethode illustriert: The method according to the invention is illustrated by the following test method:
Bohnenrostpilz (Uromyces appendiculatus): Phaseolus vulgaris (Bohnenpflanzen) werden in einem Gemisch, bestehend aus Torf und Sand, in Plastiktöpfen mit einem Durchmesser von 6 cm während 9 Tagen gezüchtet. Die Pflanzen werden besprüht mit einer wässrigen Sprühlösung, welche 0,0008 bis 0,05% an aktiven Bestandteilen, formuliert gemäss Beispiel A, B oder C, enthält. Die Behandlung besteht aus einem Besprühen des Blätterwerkes, so dass die Lösung beinahe von den Blättern herabläuft. Bean rust fungus (Uromyces appendiculatus): Phaseolus vulgaris (bean plants) are grown in a mixture consisting of peat and sand in plastic pots with a diameter of 6 cm for 9 days. The plants are sprayed with an aqueous spray solution which contains 0.0008 to 0.05% of active constituents, formulated according to Example A, B or C. The treatment consists of spraying the foliage so that the solution almost runs off the leaves.
Nach dem Trocknen werden die Pflanzen mit einer Sporensuspension (500 000 bis 700 000 Sporen pro ml) geimpft und während 7 Tagen in einer Brutkammer bei einer relativen Feuchtigkeit von 100% und bei 21 °C bebrütet. After drying, the plants are inoculated with a spore suspension (500,000 to 700,000 spores per ml) and incubated for 7 days in a brood chamber at a relative humidity of 100% and at 21 ° C.
Die Wirksamkeit der Behandlung mit den aktiven Komponenten wird festgestellt mittels eines Vergleiches der Anzahl der gebildeten Pusteln pro Blatt mit Test-Pflanzen, welche ähnlich geimpft und mit der gleichen Menge einer der Komponenten a) oder b) behandelt wurden. The effectiveness of the treatment with the active components is determined by comparing the number of pustules formed per leaf with test plants which have been vaccinated in a similar manner and treated with the same amount of one of components a) or b).
Für jede der Formulierungen gemäss Beispiel A, B und C wurde eine signifikant synergistische Wirkung gegen Rostpilze beobachtet. A significant synergistic effect against rust fungi was observed for each of the formulations according to Examples A, B and C.
