The plane tiger can potentially affect all plane trees.
It is caused by the attack of a bedbug that "sucks" on the back of the leaf.
This results in the appearance of whitish and blackish patches as well as leaf drop.
Solution to fight against the plane tiger
Spraying with insecticide is a known and most effective method.
But to respect our planet, there is a method that can be applied to organic gardening.
It is simply a matter of high pressure washing the trunks and carpenter branches with rapeseed vegetable oil to find and smother the pests.
