The Solution or Another Problem??
The Department for the Environment, Food and Rural Affairs (Defra) believes it has found a solution to Japanese knotweed. The downside is that it involves introducing another alien species from Japan!
Psyllid Aphalara itadori, a 2mm, brown bug will be released onto 'a handful' of sites this spring.
Our Views at IVM;
We feel that although this seems like a good idea at first glance, it is far from the answer to the problem. Our mains points of concern, in Layman's terms are;
-
They only control the plant - they do not eradicate it.
-
If these Japanese bugs are so good, why is there still Japanese knotweed in Japan?
-
They don't come with a insurance backed guarantee
-
How do CABI & DEFRA know for a fact that they will not feed on any other plants?
-
What will happen further up the food chain when insects/birds start feeding on the bug?
-
Will this turn into another Grey Squirrel, Red Squirrel issue?
