Notes: Abstract Field experiments were conducted to determine the influence of six commercial herbicides and of hand-hoeing on symbiotic parameters and grain yield of lentil (Lens culinaris Med.). The herbicides were sprayed at the pre-emergence stage. Number of nodules, nodule dry weight and nitrogenase activity were found to decrease with the use of Oxyfluorfen, Linuron, Metribuzin and Oxadiazon, whereas the effects of Terbutryn and Methabenzthiazuron were similar to that of hand-hoeing. Any harmful effect of herbicides on symbiotic parameters was less when seeds were inoculated with Rhizobium leguminosarum.

Description / Table of Contents: Äthyl(n-Propyl)-Zinndichlorid und seine Addukte mit Stickstoff-DonatorenÄthyl(n-Propyl)-Zinndichlorid wurde nach der Methode der Umverteilung dargestellt. Mit Phenylhydrazin, Anilin, Piperidin, n-Propylamin und n-Butylamin bildet es 1:2-Addukte, mit Benzylamin nur ein 1:1-Addukt. Die IR-Spektren der Verbindung und der Komplexe werden mitgeteilt.

Notes: Preparation of ethyl(n-propyl)tin dichloride by the redistribution-reaction method has been reported. It has been found to form 1:2 adducts with phenyl hydrazine, aniline, piperidine, n-propyl- and n-butylamines while with benzyl amine only 1:1 adduct is obtained. IR spectra of EtPRnSnCl2 and its complexes have been discussed.
