I did not see much conversation about it, I am interested to hear more opinions, is it as harmless as the marketing proposes it to be. Looks to be effective with 2 applications during hot dry weather, although costly at retail prices $20 for 300square feet. I see a more potent source where it requires a license to purchase, which is cheaper.
I know there are more effective options in the chemical herbicide realm but are there more effective organic options for herbicides besides the usual mulching, tilling etc.
