Q: I saw a video of a woman using a bleach solution to kill weeds. Wouldn’t this be cheaper and safer than using Roundup?

A:  I’m curious why folks think bleach is “safer” than glyphosate (Roundup).

The Material Safety Data Sheet for bleach warns about tissue damage, corrosiveness and burning of the skin.

The comparable MSDS for glyphosate describes it as “practically non-toxic“.

Here are my sources:

Bleach: www.sciencelab.com/msds.php?msdsId=9925000

Glyphosate: http://www.cdms.net/LDat/mp6DP042.pdf

Bleach might be cheaper to use….but I’m not convinced it is safer.
