Default How Soon To Plant After Using Roundup?

Glyphosate attacks some vital steps in the chemical defense system of

why it has taken so long for weeds to develop resistance to this
herbicide.


Did you just make that up? Glyphosate is a protein synthesis inhibitor. (I
thought it was a chlorophyll inhibitor, but I looked it up; it inhibits
5-enolpyruvyl-shikimate-3 phosphate synthase, a.k.a. "ESPS".) Once the
plant is crippled, opportunistic fungi may attack the roots, but Roundup
will kill the plants whether there are any fungi or not.
