    Description / Table of Contents: Summary 1. In 1963 spider mites (Tetranychus urticae Koch) being in hops not sufficiently controlable by organophosphorous insecticides could be controlled by a copper-sulphur combination and a Mezineb-compound. Therefore no application of an acaricide was needed. 2. In 1964, a year most suitable for a heavy buildup of spider mites, both resistant and not resistant mites could be sufficiently controlled in experiments carried out by Landesanstalt für Pflanzenschutz, Stuttgart, by compounds containing sulphur. An acaricidal treatment was not necessary. 3. Experiments carried out by two growers gave different results. Spider mites were sufficiently controlled only by compounds containing sulphur where the applications were done extensively and in no longer intervals than 8 days. 4. The most favourable results could be achieved by a coppersulphur-combination or by organic fungicides with added wettable sulphur. 5. The application of acaricides should be restricted to cases of extreme emergence only to delay the buildup of resistance of spider mites against these effective substances as long as possible or to make resistance even impossible. 6. Only early in the season applications of copper-sulphur compounds or organic fungicides containing sulphur gave sufficient control of spider mites in hops. That means, that the first application has to be done before the first spider mites occur.
    Notes: Zusammenfassung 1. 1963 war es möglich mit Kupfer-Schwefel-Kombinationen und einem Mezineb-Präparat Spinnmilben, die mit organischen Phosphorsäureester-Verbindungen nicht mehr ausreichend zu bekämpfen waren, niederzuhalten und die Anwendung eines Akarizides überflüssig zu machen. 2. Auch 1964, einem Jahr mit stärkstem Spinnmilbenauftreten, gelang es in den Versuchen der Landesanstalt für Pflanzenschutz, Stuttgart, die Spinnmilben, gleich ob widerstandsfähig gegen Phosphorsäureester oder nicht, mit schwefelhaltigen Präparaten niederzuhalten. Eine besondere Behandlung gegen Spinnmilben war nicht notwendig. 3. 2 von Praktikern gespritzte Großversuchsflächen brachten unterschiedliche Ergebnisse. Wo gründlich, sauber und in Abständen von nicht über 8 Tagen gespritzt wurde, ließen sich die Spinnmilben mit den ausgebrachten schwefelhaltigen Fungiziden niederhalten. 4. Am günstigsten wirkten die Kupfer-Schwefel-Kombinationen oder organische Fungizide, die einen Netzschwefelzusatz erhielten. 5. Die Anwendung von Akariziden sollte sich nur auf Notfälle beschränken, um eine Resistenzbildung der Spinnmilben gegen diese Wirkstoffe möglichst lange hinauszuzögern oder unmöglich zu machen. 6. Nur die Frühanwendung von Kupfer-Schwefel-Kombinationen oder schwefelhaltigen Präparaten bringt gegen Spinnmilben in Hopfen Erfolg. D. h. die Mittel sind so zeitig anzuwenden, daß vor dem ersten Auftreten von Spinnmilben gespritzt wird.

    Description / Table of Contents: An einer Serie von zehn teilweise erstmalig synthetisierten α-substituierten Styrolen wird durch kinetische Messungen bei 110°C gezeigt, daß solche Verbindungen zusammen mit Styrol nach dem Mechanismus einer Copolymerisation reagieren, jedoch je nach dem Charakter des α-Substituenten verschieden stark retardieren oder zur Kettenübertragung führen.Hierbei zeigen α-Alkylstyrole kaum Kettenübertragung, jedoch eine um so größere Retardierung, je sperriger der α-Substituent ist. α-Arylalkylstyrole vom Typ 4-substituierter 2.4-Diphenylbuten(1)-derivate führen hingegen zu einer merklichen Kettenübertragung, wie die übertragungskonstanten von 0,29 und 0,26 der Verbindungen 4-Methyl-2.4-diphenylpenten(1)bzw. 2.4.4-Triphenylpenten(1) beweisen.Die einzelnen Geschwindigkeitskonstanten für Kettenwachstum und Kettenübertragung werden berechnet oder größenordnungsmäßig abgeschätzt.
    Notes: The copolymerization of styrene with a series of ten α-substituted styrenes, partially synthesized for the first time, was investigated by kinetic measurements. All compounds react with styrene according to the mechanism of copolymerization. The extent of the observed retardation or chain transfer reaction depends on the chemical nature of the α-substituent.Some α-alkylstyrenes scarcely show chain transfer, yet the more bulky the α-substituent is, the more retardation could be observed. On the other hand α-arylalkylstyrenes of the type of 4-substituted 2.4-diphenyl-1-butene-derivates cause an evident chain transfer as can be seen from the chain transfer constants of 0,29 and 0,26 from 4-methyl-2.4-diphenyl-1-pentene and 2.4.4-triphenyl-1-pentene, respectively.The single rate constants of chain propagation and chain transfer are calculated or estimated.
