Aufnahme von Atrazin-Metaboliten durch Hafer neun Jahre nach der Herbizid–Applikation

Uptake of atrazine metabolites by oat plants nine years after the herbicide application The uptake of atrazine metabolites by oats under field conditions was investigated 9 years after the herbicide application. In the spring of 1973 the soil was treated with ¹⁴C-ringlabeled atrazine and cultivated with various plant species each year. The soil was seeded to oats in early May of 1982. In August the oat plants were harvested and analysed. 2-Hydroxy-4-amino-6-isopropylamino-s-triazine and 2-hydroxy-4-ethylamino-6-amino-s-triazine were identified in conjugated form in the plant material. Neither free atrazine nor any other phytotoxic 2-chloro-metabolites could be found.
