    Description / Table of Contents: Samenvatting Na overenting op een medium dat tolchlofos-methyl bevatte, raakten enkele isolaten vanRhizoctonia solani gewend aan 500 maal de dosis die oorspronkelijk bijna alle groei verhinderde. Resistente isolaten vanR. solani bleven minder gevoelig voor tolchlofos-methyl na vijf overentingen op een medium zonder het fungicide. De pathogeniteit van resistente isolaten was niet verminderd, maar hun groeisnelheid op PDA was significant vertraagd vergeleken bij die van de oorspronkelijke isolaten. Isolatie van de resistente stammen werd niet verbeterd op een selectief medium waaraan tolchlofos-methyl was toegevoegd.
    Notes: Abstract Isolates ofRhizoctonia solani were adapted in vitro to grow on a medium amended with tolclofos-methyl at a concentration 500 times that which initially almost completely inhibited growth. Acquired resistance was retained after five transfers on a fungicide-free medium. Pathogenicity of resistant isolates was not reduced, but their growth rates on PDA were significantly lower than those of the original isolates. Recovery of the resistant isolates was not improved on a selective medium amended with tolclofos-methyl.

    Description / Table of Contents: Surface Protection of Work Pieces in the Manufacturing Prozesses of Mechanical EngineeringUnprotected surfaces of work pieces especially coarse surfaces of cast iron are usually rusting and contaminating easily.Their cleaning is as well most difficult as expensive for under these conditions really clean surfaces scarcely can be obtained.The costs for varnishing depend on the adhesiveness of the first coat of paint. Economical painting-methods can rarely be applied to work pieces if these are mechanically worked upon already.Therefore early surface protection of cast iron can be of great advantage as the charges for surface cleaning are decreased and the endurance of the coat of paint is improved. It also helps to improve cleanliness and hygiene of work.Two examples show the procedure and the advantage of ground-coating in the manufacturing prozesses of mechanical engineering.
    Notes: Ungeschützte Werkstückoberflächen setzen in der Regel Rost an und verunreinigen schnell, insbesondere dort, wo es sich um rauhe Gußoberflächen handelt. Die Reinigung ist dann meist schwierig und auch teuer. Wirklich saubere Oberflächen werden aber auch dann nur selten erzielt.Mit dem Haftvermögen des ersten Farbauftrages steht oder fällt der Aufwand für die Lackierung. In den Fällen, in denen die mechanische Bearbeitung des Stückes bereits erfolgte, ist die Benutzung rationeller Farbauftrags-Verfahren nur selten möglich. Ein frühzeitiger Oberflächenschutz des Gusses kann deshalb sehr vorteilhaft sein. Er senkt die Kosten für Oberflächenreinigung und erhöht die Haltbarkeit des Farbauftrages. Er verbessert außerdem die Arbeitshygiene und fördert die Sauberkeit im Betrieb.An zwei Beispielen werden der Aufwand und die Vorteile des Grundanstrichs im Fabrikationsablauf des Maschinenbaus aufgezeigt.
