Best results can be achieved when using this contril-method at the beginning of swarming of the moth in late April. Per tree (about 20m of height) 200 to 400 ml of Acetamiprid solution (20% a.i.) is needed. About the problems with the phytotoxicity of the solvent (N-Methylpyrrolidon) which was sometimes observed and irregular dispension of the systemic insecticide in the crown is also reported.
