The reaction of Ambrosia artimisiifolia L. was studied in recent years using field and greenhouse trials in Geneva and in Changins and 2009 in ring tests in various European countries within a EUPHRESCO project. The results showed that Ambrosia reacts on a non-lethal control with re-sprouting and is able to produce – even in reduced quantities – pollen and viable seeds. The choice of control methods depends on the status of the invasion and on the type of the site. The main strategy of all methods must aim preventing the formation of viable seeds and must contain a sequential observation of the treated site. This paper discusses experience on control methods within and outside of agriculture in Switzerland
Grass-based beef production is markedly less productive than intensive year-round indoor-housing system-based production. Agroscope experts therefore studied how grass-based farms can produce both economically and in an ecologically sound manner.
Orchard crop spraying using unmanned aerial spraying systems commonly referred to as drones can lead to drift, posing a risk to residents and bystanders. The study shows that the risks arising from this are taken into account by the current registration process.
Trials conducted by FiBL have shown that conversion to organic farming also promotes endangered Red List species such as the carabid beetle species Amara tricuspidata. This species and other species consume seeds of forbs and grasses and thus supports natural weed control.
