Re: aphids and mandevilla/ now mealy bugs

Marathon works best on softer new growth. Older woodier stems does not seem 
to translocate the insecticide as well as younger stems. I tried it on 
poinsettias but it was not too effective on older plants.

Neem based pesticides seem to work well on mealy bugs, but they do not kill 
the bugs right away, just disrupt their life cycle and prevent younger mealy 
bugs from becoming adults,
