A single foliar application of glyphosate [N-(phosphonomethyl)glycine] at 2.2 kg/ha controlled fragrant waterlily (Nymphaea odorata Ait.). Seeds that germinated during the year of glyphosate treatment or the following spring reestablished the fragrant waterlilies. A second application of glyphosate, once the seedlings had reached the surface of the water, resulted in long-term control.

This article uses age-depth models based on 29 accelerator mass spectrometry (AMS) dates from charred plant macroremains (seeds, chaff), wood charcoal, and snail shells found in two moats from the settlement Fidvár near Vráble (SW Slovakia) to improve the absolute chronology of the Early Bronze Age in central Europe. The charred macroremains were taxonomically identified to species or genus level and the lifespan of the objects and the archaeological context were considered carefully. The selected snail shells were identified to provide reliable age information. This study demonstrates that under certain conditions, ditch archives can be well suited to contribute to archaeological chronologies. For the first time, the transition from the Hatvan to the Únětice period is dated absolutely.
