I use it occasionally and have found no reduction in the number of earthworms. One spraying will not get rid of Bermuda grass in my experience. I have nutgrass in one bed and have to use it because no mulch short of 6 inches of concrete will stop that stuff. It is effective in killing it back but I still have a problem with it. That bed is also the one that gets the most Round Up and is also my most productive bed so I don't think it is hurting the tomatoes but if you happen to let it drift onto them it will kill them much better than it will kill Bermuda grass.
