Invasive weeds in America’s Western states: restoring balance using biological control
In many of America’s Western states, invasive weeds such as houndstongue (Cynoglossum officinale), Russian knapweed (Rhaponticum repens), yellow and Dalmatian toadflax (Linaria vulgaris and Linaria dalmatica), oxeye daisy (Leucanthemum vulgare), and hoary cress (Lepidium draba) are serious problems. However, research shows that biological control, as part of an integrated weed management strategy, offers the potential for a cost effective and efficient way of reducing invasive plant species to levels below acceptable damage thresholds.
Past, present and future – reflections on the XV International Symposium on Biological Control of Weeds
Invasive alien weed species have been a global environmental and human health issue for decades. In 1969, CABI organised the first International Symposium on Biological Control of Weeds (ISBCW) in Delémont, Switzerland. Weed biocontrol research was then in its early stages and 20 scientists attended.
