Description

Schädlingsbekämpfung Es wurde gefunden, daß Rhodanverbindungen der allgemeinen Formel N C S - R - S C N mit Vorteil als Mittel zum Bekämpfen von Schädlingen, insbesondere Pflanzenschädlingen, verwendet werden können. In der allgemeinen Formel bedeutet R einen zweiwertigen geraden oder verzweigten aliphatischen Kohlenwasserstoffrest von 5 oder mehr Kohlenstoffatomen, der auch durch Sauerstoff- oder Schwefelatome oder Sulfongruppen unterbrochen sein kann. Diese Rhodanide zeichnen sich durch hohe Giftwirkung auf die Schädlinge aus und besitzen dabei überraschend geringe blattschädigende Eigenschaften.Pest Control It has been found that rhodane compounds of the general formula NCS - R - SCN can be used with advantage as agents for controlling pests, in particular plant pests. In the general formula, R denotes a divalent straight or branched aliphatic hydrocarbon radical of 5 or more carbon atoms, which can also be interrupted by oxygen or sulfur atoms or sulfonic groups. These rhodanides are distinguished by their high poisonous effect on the pests and, at the same time, have surprisingly low leaf-damaging properties.

Als Verbindungen der beanspruchten Art sind beispielsweise zu nennen das i, 5-Dirhodan-pentan, i, 6-Dirhodan-hexan, i, 8-Dirhodan-octan, 1, 12-Dirhodan-dodecan, ferner auch das 6, 6'-Dirhodan-dihexylsulfid, der 5, 5'-Dirhodan-dipentyläther u. dgl.Examples of compounds of the type claimed are the i, 5-dirhodan-pentane, i, 6-dirhodan-hexane, i, 8-dirhodan-octane, 1, 12-dirhodan-dodecane, and also the 6, 6'- thiocyanogen-dihexyl sulfide, 5, 5'-thiocyanogen-dipentyläther u. like.

Die erfindungsgemäßen Mittel können als solche, in wäßriger Emulsion, in organischen Lösungsmitteln gelöst oder auch in fester Form auf Substraten aufgebracht angewendet werden. Man kann den Mitteln gleichzeitig bekannte Haft-, Netz- oder Streckmittel zusetzen und kann sie auch gemeinsam mit anderen bekannten fungiciden oder insecticiden Mitteln in Anwendung bringen. Die Anwendung erfolgt durch Versprühen, Verspritzen, Verstäuben, Verstreuen oder Verstreichen.The agents according to the invention can be used as such, in aqueous emulsion, dissolved in organic solvents or applied to substrates in solid form be applied. You can use the means at the same time known adhesive, network or Add extenders and they can also be used together with other known fungicides or use insecticides. The application is carried out by spraying, Splashing, dusting, scattering or spreading.

Die erfindungsgemäßen Mittel sind vor allem wirksam gegen Pflanzenschädlinge, insbesondere saugende und fressende Schädlinge des Obst-, Wein- und Gart.enbau-es,'wie z. B. Blatt-, Blut- und Schildläuse, Thrips, ferner Käfer, Raupen, wie Traubenwicklerraupen, rote Spinne, Erdflöhe.u. dgl. Die Mittel sind weiterhin zu gebrauchen gegen. Fliegen, Mücken, Schnaken, Moskitos, Wanzen, Schwaben, Ameisen und ähnliche Schädlinge. Beispiel I 2o Gewichtsteile 1,5-Dirhodan-hexan werden mit io Gewichtsteilen Tetrahydronaphthalin und 2,o Gewichtsteilen Methylcyclohexanol gemischt und sodann unter Rühren mit 5o Gewichtsteilen Türkischrotöl versetzt, wobei eine klare Lösung entsteht. Diese Lösung wird in i0/,iger Konzentration, auf wirksame Substanz berechnet, in Wasser emulgiert und dient als Spritzmittel gegen Gartenbauschädlinge, wie z.B. Blutläuse, Raupen u. dgl. Die gebildete Emulsion ist auch bei längerem Stehen beständig. Beispiel 9, ,3 Gewichtsteile 6,6'-Dirhodan-dihexylsulfid, i Gewichtsteil Natriumsalz des sauren Schwefelsäureesters eines Fettalkoholgemisches, das durch Reduktion von Kokosöl gewonnen wurde, und 6 Gewichtsteile Wasser werden in klare Lösung gebracht, die in i0/,iger wäßriger Verdünnung mit Vorteil zur Bekämpfung von Obstbauschädlingen verwendbar ist. Die Emulsion bewirkt rasche Abtötung der Schädlinge, ohne daß dabei eine Schädigung der Blattsubstanz stattfindet. Beispiel 3 15 Gewichtsteile I, 6-Dirhodan-hexan werden auf 85 Gewichtsteile eines inerten Trägerstoffes, wie Calciumcarbonat, Talkum, Kieselgur u. dgl. aufgebracht. Das erhaltene Streupulver kann mit Vorteil zur Bekämpfung von Schwaben, Wanzen und ähnlichen Schädlingen verwendet werden.The agents according to the invention are particularly effective against pests of plants, especially sucking and eating pests of fruit, viticulture and Gart.enbau-es, 'such. B. aphids, blood and scale insects, thrips, also beetles, caterpillars, such as grape moth caterpillars, red spiders, Erdflöhe.u. Like. The funds are still to be used against. Flies, mosquitoes, gnats, mosquitoes, bed bugs, Swabians, ants and similar pests. EXAMPLE I 20 parts by weight of 1,5-dirhodan-hexane are mixed with 10 parts by weight of tetrahydronaphthalene and 2.0 parts by weight of methylcyclohexanol and then 50 parts by weight of Turkish red oil are added with stirring, a clear solution being formed. This solution is calculated at a concentration of 10%, based on the active substance, emulsified in water and used as a spray against horticultural pests such as blood lice, caterpillars and the like. Example 9, 3 parts by weight of 6,6'-dirhodane dihexyl sulfide, 1 part by weight of the sodium salt of the acid sulfuric acid ester of a fatty alcohol mixture obtained by reducing coconut oil, and 6 parts by weight of water are brought into a clear solution, which is diluted in 10/1 can be used with advantage for combating fruit pests. The emulsion quickly kills the pests without damaging the leaf substance. Example 3 15 parts by weight of I, 6-thiocyanogen-hexane u to 85 parts by weight of an inert carrier material, such as calcium carbonate, talc, diatomaceous earth. Like. Applied. The scattering powder obtained can be used with advantage for combating Swabians, bed bugs and similar pests.
