After days of work, I may have tracked down the source of the
statement that imidacloprid is the most commonly used insecticide on
the planet.

From Bayer:

> Confidor(r) is already the world's leading agricultural insecticide. In 2006 Bayer CropScience launches a unique new formulation technology making its active ingredient, imidacloprid, even more effective against sucking insects. Confidor OTEQ(r) is a patented formulation ensuring improved foliar adhesion, better penetration and enhanced rain fastness.
