Florida Department of Agriculture and Consumer Services Lab Testing 

What do they actually test for?  I started asking these questions after they told me a nasty looking algae bloom showed up negative for pesticides and herbicides.  They did not test for the optional herbicides during their for cause bee kill investigation of Costa Honey Farm, even though they found an herbicide in a soil sample at the fence line.  You can't find what you're not looking for.  See the PDF below I received through a public information request.

Florida Department of Agriculture and Consumer Services does not test for most pesticides and herbicides sold at the Home Depot.
