[Spread of Ambrosia elatior in rural areas (investigation performed during the years 1985 and 1986 in southern Drome)].
The settings of Ambrosia development are not only construction zones, waste grounds, road works; a country extension has been observed; more and more varied lands under cultivation (cereals, sunflowers, peach-trees...) are overgrown and the advance, toward South Drome and Ardèche since few years, clearly indicates that all the Rhone Valley is under threat. Several forms of spreading are possible, sometimes very unexpected, so, for instance, the irrigation by spraying. The struggle must associate the mowing when it is easy (town zones, verges...), selective weed-killer use and a good farming rotation (country zones). A better information of town councils about those problems is also absolutely necessary for us.
