Compared with all the systemic contact herbicides used before roundup, it is a saint. Actually a salt that breaks down to organics when it contacts the dirt. And the LD50 is way up there.

I use a blue dye to prevent over spray and contact. Also it's generic now at half the price.

I could not run my garden business without it, but it's greatest benefit is maintaining good soil structure by allowing no-till farming.
