I used Zerotol a few years ago. Don't remember having any negative problems with it. Don't recall the rate used off hand but I know it's kinda high compared to other products we use. Just Don't mix it with any fertilizer type products. We spray at 2 gal water/1000. It's a knockdown type product, so it won't be around long after you spray it. Check the label as it might be ph sensitive.
