I think they are referring to the loophole that allows farms to use organic chemicals on produce that is labeled "Organic".

In chemistry, an organic chemical is a compound that contains lots of carbon, or carbon chains. The loophole allows the use of these organic compounds as pesticides. The downside is that these are typically much more of a broad spectrum than the cutting edge pesticides. This means that unlike the new narrow-spectrum pesticides (which are often designed so they only affect the physiology of a specific order of invertebrate) the old-school organic chemical pesticides are harmful to pretty much everything it comes in contact with.

Here is some more info on the issue: http://www.ocf.berkeley.edu/~lhom/organictext.html
