The petition was:-

"We the undersigned petition the Prime Minister to refuse to reinstate
Aminopyralid as a weed killer in Britain.”
Details of Petition:

: ((Huge Snip))

So effectively big business wins as usual..

The interesting data on this weedkiller is...
"Under aerobic conditions, degradation of aminopyralid in five different
soils resulted in the production of CO2 and non-extractable residues.
Half-lives ranged from 31.5 to 533.2 days in 5 soils. For risk assessment
purposes, EPA used a half-life of 103.5 days.

Aminopyralid photolyzed moderately slowly on a soil surface. The half-life
was 72 days and CO2, non-extractable residues and small amounts of acidic
volatiles were the degradates."

So it may be around for a bit yet in some soils even if everyone keeps to
the new rules.
