Cleanest/Dirtiest Produce

I'm constantly using Locavore to get fresh, in-season produce, but not all of the farmers at the local markets are organic. I'd love to see the integration of a cleanest/dirtiest (pesticide) produce list that helps me keep track of which fruits and veggies are safe to get conventional and which are best to buy organic. I already use Dirty Produce on my iPhone for this, but it'd be very handy (and appropriate) to have this info included within Locavore.

Thanks!
