I'm in zone 6 and our guide books tell us that for taking care of lilacs and
systemic insecticide must be used. What exactly is that and what makes it
different from a regular insecticide?

Systemic materials will be taken up in the roots and
absorbed through the leaves so that insects that feed on
the plant will be targeted, where other formulations
will be basically a topical application leaving a
residue on the plant rather than in the plant.
