To release the psyllid or not release the psyllid, that is the question.
The Government will be announcing their decision later this month on this biological control. There are many factors to consider in making this decision, including the robustness of the science underpinning the application to release the psyllid, the level of control that can be expected and the risk to the environment. There is of course a risk to the environment in not releasing it! Japanese knotweed continues to spread and invade our urban and rural areas, most of it is still not undergoing a control programme! The release of the psyllid may go some way to redressing the ecological balance and to reduce the amount of future spread, but will not however eradicate the knotweed.
Additional control measures will continue to be needed therefore. Whether this is an herbicide programme for long term control or a quicker alternative, Wreford can help you with your problem.
