As the name says, it definitely kills kudzu and you can notice it in under 12 hours or at least i could. BUT, thats about all it does, i was hoping it would kill other weeds and grass and so on but all it did to them was feed them. I think they grew more when i sprayed them lol, but as i said if your looking for something to kill kudzu this works and it only takes 1 and a half TEA spoons per gallon for it to work. I had to buy some grass and weed killer separately.
