Re: Cheap & environmentally freindly way to kill grass & weeds?

Really something like Roundup is about the best for your needs and it's relatively environmentally benign. I wouldn't drink it though.

Quote: Human and mammalian toxicity
Glyphosate itself is practically nontoxic by ingestion or by skin contact. The acute oral toxicity of Roundup is > 5,000 mg/kg in the rat.[14] It showed no toxic effects when fed to animals for 2 years, and only produced rare cases of reproductive effects when fed in extremely large doses to rodents and dogs. It has not demonstrated any increase in cancer rates in animal studies and is poorly absorbed in the digestive tract. Glyphosate has no significant potential to accumulate in animal tissue. [15][16]

Not only is glyphosate used as five different salts but commercial formulations of it contain surfactants, which vary in nature and concentration. As a result, human poisoning with this herbicide is not with the active ingredient alone but with complex and variable mixtures. [17]

A review of the toxicological data on Roundup shows that there are at least 58 studies of the effects of Roundup itself on a range of organisms.[18] This review concluded that "for terrestrial uses of Roundup minimal acute and chronic risk was predicted for potentially exposed nontarget organisms". It also concluded that there were some risks to aquatic organisms exposed to Roundup in shallow water. More recent research indicates glyphosate induces a variety of functional abnormalities in fetuses and pregnant rats.[19] Also in recent mammalian research, glyphosate has been found to interfere with an enzyme involved testosterone production in mouse cell culture[20] and to interfere with an estrogen biosynthesis enzyme in cultures of Human Placental cells.[21]

Studies have shown that the application of Roundup on wheat crops a week before harvesting results in higher glyphosate residue in the resulting grain and in the baked flour. [22]

All I have to say is California, France and Germany.

If you can afford it, buy commercial RoundUp. It does not contain the extra crap they throw in. But you must be patient, it takes a week or so before any sign of it working. Monsanto adds other ingredients in the residential brands to give you the 'instant' kill look.

Round-Up I was under the impression is 1) Expensive
2) Not environmentally friendly, and 3) Works on weeds but not on grass and stuff (which I need to kill too in the concrete.)

1) Round-up in concentrate is very cost effective. Especially if applied with a hand sprayer. I've had 1 bottle of concentrate for about 8 years and have a big yard and a long driveway that wants to grow weeds in the cracks

2) I don't have any 3 headed (you name the critter)frogs or toads around here. Been using for 25 years at this house.

3) Glycosphates (brand name Round-Up) work best on grasses but works well on some broadleaf weeds.

4) I don't own any stock in the company

1) depends on what you consider expensive
2) since vegetation is part of the 'environment' and Round-Up kills all vegetation, one could say it's bad for the "environment".
3) it is a non-selective herbicide... kills all plants**

Given our daily chances of rain this time of year, you'd be better off applying one of the consumer products that 'works' quickly vs the slower commercial products.

**some 'woody' plants are somewhat resistant, but I doubt you have many of those growing in your driveway cracks.

Oh, I don't know what you are so worried about. God plans to kill all of us anyway.

If you decide to use Roundup, just use the absolute minimum necessary and apply it very sparingly. Understand how it works and use it accordingly.

There is a BIG difference in using it as a spot treatment and applying it to vast acreages.

Use common sense with chemicals...ALL chemicals.
