摘要: Summary Experiments were conducted in a glasshouse and controlled-environment rooms to investigate the effects of temperature, light, soil moisture humidity on activity ioxynil salt ester formulations applied Stellaria media L. Raising temperature after spraying increased ester, whilst changes had little effect. Activity was by high spraying, whereas low before markedly reduced susceptibility S. both formulations. When intensity natural daylight varied shading, greatest where post-spraying light levels either very or high. Ioxynil consistently greater than rooms. This may be partly due wide diurnal fluctuations occurrence periods glasshouse. Rasuma Influence de l'environnement sur l'activite l'ioxynil sel et en application media Des experiences ont ete installees serre phytotron pour etudier l'influence la lumiere l'humidite du sol ainsi que l'atmosphere l'ioxynil, contre En elevant apres pulverisation augmentait l'ester, tandis des variations dans eu peu d'effet. L'activite s'est vue augmenter grâce une humidite atmospherique elevee pulverisation, qu'une basse avant diminue nettement sensibilite vis-a-vis deux Lorsqu'on variait le niveau naturelle, etait maximal avec niveaux ou tres bas hauts pulverisation. L'activite uniformement superieure celle les chambres conditionnees. Cela s'explique partie par grandes diurnes d'humidite periodes forte luminosite serre. Zusammenfassung Einfluss von Umweltsfaktoren auf die Wirksamkeit Ioxynil Salz/Ester gegen media Versuche wurden im Gewachshaus sowie einer Klimakammer uber den Einfluss der Temperatur, Lichts und Boden- Luftfeuchtigkeit Salz- Esterformulierungen Ioxynils ausgefuhrt. Als Temperatur nach Spritzung erhoht wurde, nahm Esters zu, indem Veranderungen wenig auswirkten. Die Salzes wurde durch starke aber niedrige Bodenfeuchtigkeit vor verminderte auffallend Empfindlichkeit gegenuber beiden Formulierungen. naturliche Lichtintensitat Schattenwirkung verandert wirkte Ioxynil-Ester am starksten bei entweder sehr hohen oder niedrigen Lichtintensitaten Spritzung. Die war stets hoher als Klimakammern. Das hangt zum Teil davon ab, dass Schwankungen zeigen Perioden vorkommen.
