The efficacy of Quassia extract with a standardized content of Quassin was proved in various field trials in
different regions during three years. The amount of Quassin of 6 g/ha/m tree height will be recommended to
practice. It is not important to have a contact effect on the eggs. The larvae must feed on the product before
they enter the fruit. There is a very good efficacy on primaray infestation. Furthermore, there is even an efficacy
on secondary infestation. Thus, even if due to difficult conditions during application or not optimal termination
of the treatment the efficacy on the primary infestation is not entirely sufficient, the secondary infestation
will be controlled better.
