2015 will be the 5th season this highly invasive weed has been in my backyard. It has taken over an entire section of my lawn around my vegetable garden and is slowly encroaching the vegetable garden as well. I have to pull it up by hand from the garden, and keep an eagle eye out for its emergence.
Clemson extension in South Carolina says to use a 2 or 3 way broadleaf herbicide mix applied twice 30 days apart.
An excellent site I found from the state of Georgia(why is it all the better sites are in Georgia or NC?) is http://www.walterreeves.com/lawn-care/chamberbitter reports that a pre-emergent can be used in Feb. through March; use 2 applications.
This site also reports ... read more

My Basenji dog greedily ate some chamberbitter in my back yard, and for the next two days he vomited up all his food. Then for three days he pooped yellow seeds. So I investigated and identified chamberbitter. He seems fine now, a few days later. I haven't found any info re the plant's toxicity to dogs; it seems people use the leaves medicinally; I haven't found any info re the seeds. This stuff is everywhere here so if anyone has more info re its effect on dogs who eat it, I would appreciate that.

Hideous! Horrible plant! I don't give a happy darn about it's beneficial properties-they are far outweighed by the invasive nature of this evil weed. I've pulled it up for years and tried everything, including weekly doses of roundup (it just laughs at me every time I spray)

I had a nice bed and it took over-choked out enough plants so I had to essentially start over. Tried changing it into turf and the buggers were more prolific than before. THEN I had a tree company dump a full load of wood chips and the little nightmares STILL thrived (3"of hardwood wood chips, mind you)

It's taken over our entire neighborhood. I'm not exaggerating. If this were plant warfare, we wouldn't stand a chance. Come to think about it...DESTROY DESTROY DESTROY!

I don't care how much Chamber Bitter grows on our property. It is an antibiotic, a stone breaker, treats urinary problems and I have a scientific paper that says it is better at curing Hepatitus B than medication. Phyllanthus urinaria can grow all over our 17.5 acers it is wants to.

Do not let this plant take a foothold. I got this in a load of topsoil 2 years ago, and it's spread like wildfire. Veg. garden, lawn, and flower bed were infested. I had to kill off my flower bed with roundup and put down pre-emergent herbicide just to keep it suppressed. Solarizing my vegetable garden bed now, don't know the results yet. Lawn is bouncing back through frequent mowing and weed & feed.
My biggest recommendation: If you see it, kill it. DO NOT let it go to seed.

I agree with the previous negative comments. Do not let this get a foot hold. If not pulled before seeds form, it will be everywhere the next season. Not kidding. This will take over a flower bed or veggie bed with what seems like lightning speed. It looks kinda cute when it first comes up, but don't let it fool you. It's definitely in the "thug" category.

Phyllanthus urinaria (Known here as chamber bitters) This weed will take over, so if you see only a few get them out of your lawn or garden as fast as possible. If your lawn is St. Augustine grass, you will kill the grass before you kill the weed if using herbicides. Any attempts to pull it up once it is more than a few inches high will cause seeds to fall from the underside of the leaves, in addition to it taking the top inch or two of topsoil with it. I've been doing battle with pest for years. Dandelions and crabgrass seem benign by comparison.

Chamberbitter is used for curing blennorrhagia, diabetes, dysentery, flu, tumors, jaundice, vaginitis, against headache, fever, conjungtivitis, menstrual disorders and dyspepsia. It is used against colic, as an effective remedy to eliminate gall and kidney stones. It is also used for urinary tract infection, bladder inflammation and for other kidney and liver problems. This info was gathered off of the web. Search for chamberbitter which is another name for it. Pretty invasive if you ask me. I have tons of it. Burning it early does a pretty good job of stopping it for a little while. Good luck.

I can't think of anyone wanting to plant this purposely. It's been comming up all over my property. It's almost like a tribble........born pregnant. It's resistant to RoundUp.

This weed is like a disease!!! It spreads and spreads and you can't get rid of it! In just a couple months it has spread through my vegetable garden, my butterfly garden, and all through my flower borders along the sidewalks. When you go to pull it up, it takes about a pound of soil per plant and whatever root fragments are left in the soil regenerate at least 3 more plants to replace the old one. This is probably the worst weed I have encountered in my life and I recommend to anyone, DO NOT PLANT THIS. Also I'm assuming it is poisonous, because it is a member of the euphorbiacea family.
