Bonide Captain Jack's Lawnweed Brew, 128 oz Ready-to-Use Spray, Fast-Acting Formula Controls Weeds, Moss, Algae, Lichens & Disease

Seems to be an organic dandelion killer that works. Make sure you saturate the dandelion.

Did not work in the bootheel of Missouri! Barely burned the leaves of several weeds.I bought this after seeing it on The Garden Answer you tube video. She was trying it out too.

Best way to get rid of dandelions! Does not kill grass. I used to get dandelions out with a weed prong. This was very backbreaking work and if any of the root was left in the ground, the weed would regrow again. I used this weed killing product this spring and yard looks fantastic… No dandelions!

It does not appear to kill grass, only the weeds

Not terribly effective on severe weeds. I'd say that about 30% of my sprayed area actually curled up and died. The rest recovered from the spraying and are thriving.

It’s to bad there isn’t a more concentrated version for a hose or something. I had to use both bottles for 1500sqft and it didn’t even kill everything. I had to do multiple passes on all of the weeds. It did work within an hour, I did notice some browning of the weeds and haven’t came back yet but it’s still overpriced and the fact has to use both bottles for it work is insane

This kills broadleaf weeds! Dead. Depending on conditions, it may also burn your lawn a tiny, little so just spray the weeds.

spray on algae & moss only turned it black and later I noticed it coming back. Must not have killed the roots. Didn't kill some weeds, I sprayed it on either.
