Looking for some opinions. Last year I used a Weed B Gon for my lawn to remove vetch that was spreading in the front yard. To apply on my lawn, I used a sprayer that I attached at the end of my lawn hose. Not really thinking it would be an issue, but later in the year, I rinsed the same sprayer and used it to apply a fungicide to my vegetable garden. I am wondering if I have contaminated my vegetable garden with the Weed B Gon product? Is there a way I can get my soil tested or should I believe that everything is OK. Any response would be welcomed. Thanks.
