It has more to do with newer technology than with marketing.

There is nothing that can be used just once and be effective, and malathion
is as old as the hills.

Newer technologies require multiple treatments to kill everything, as does
malathion. The newer stuff is simply more effective.

If you really want to do it right and avoid the development of resistant
insect strains, go with IGR's - some of the newest technology.

Let's be honest, you're a PHB at a pesticide company, which would you
pick to market, the one that you apply once and you're done for the year,
or the one where you apply it once, it seems to resolve the problem,
and a few weeks later they are back stronger than ever...
