I searched Google for diatomaceous earth and vegetable gardens and get thousands of results of people successfully using it. Numerous experts say as long as you use food grade vs. pool filter DE, you are good to go. Not sure why Garden Safe is having trouble meeting this standard.

As for their Garden Safe Fruit & Vegetable Insect Killer, the concentrations seem incredibly low to be effective. Just 0.02% Pyrethrins and .20% Piperonyl Butoxide.
