Biological control of European frogbit in North America
European frogbit, Hydrocharis morsus-ranae, is a free-floating aquatic plant with heart-shaped leaves. Native to Europe and parts of temperate Asia and Africa, this plant is considered invasive due to its socio-economic and environmental impacts. European frogbit was introduced into North America as an ornamental plant and has since spread to rivers, lakes and inland waters. CABI is exploring potential biological control agents that can be used to help reduce the expansion of European frogbit through North America.
