An insect is to be released in the UK to stop the spread of the non-native invasive plant Japanese Knotweed which can destroy property and costs the economy more than £150million a year to control and clear.
Japanese Knotweed is listed by the World Conservation Union as one of the world's 100 worst invasive species. It grows vigorously at a rate of up to a metre a month, including through concrete and drains, causing damage to roads and buildings and costing millions of pounds to remove each year.
