I don't see a material data sheet (didn't spend long searching) for that product online. Most products like that do have such information readily available. Maybe it's just a little harder to find than some others. What does it say on the product label?

In any event, I can't imagine that the product would have any negative effect on crops located outside the area where you applied it. As long as the plant isn't in the immediate area of application, there's no need to avoid eating it.

Thanks brandon7 -- Guess I won't abandon garden:) After much research online, found Greenlightw/conserve to be best/organic product, but discouraged that this will be a continual process -- plan B is to move to WA! Peace,
