Where's the data showing bananas are more heavily treated than any other fruit?

Here is some actual data from 2009, with analysis for Brazil by a proper agency (ANVISA's PARA, Project for Analysis of Agrotoxic Residue in Food):

It's in Portuguese, but you can find a nice color table in page 7 with fruit and vegetable names (rows) and states (columns) providing an idea (red == bad).

Bananas do better than pretty much anything else tested there.
