Gary Philpotts, Chair of the Common Sense Gardening Group said: "Gardeners that find Japanese knotweed in their gardeners will rightly be concerned about this rapidly spreading perennial weed, however, it can be controlled with approved glyphosate products available at garden centres and DIY stores. You will need to be patient as it can take up to three to four seasons to be eradicated.
"It is estimated that Japanese knotweed costs around £165 million to control in the UK. This highlights how important glyphosate is and how removal of this crucial tool would make control even more difficult and costly.
"The indecision of Member States and the need for an 18 month extension demonstrates how politicised the regulatory process has become at the EU level. Hopefully this 18 month extension will provide an opportunity for common sense and scientific evidence to prevail. Failure to re-licence glyphosate for the full 15 year term would be contrary to the science and remove a key tool which helps gardeners deal with a range of weed pressures, including Japanese knotweed."
