Glyphosate in Glen Canyon

There’s increasing evidence that glyphosate – the herbicide Monsanto sells under the names Roundup and Aquamaster – is dangerous to human health, doesn’t degrade in the soil as the company claims, and is a dangerous probable carcinogen. Since SF Department of the Environment changed its classification from Tier II (More hazardous) to Tier I (Most hazardous), SF Rec and Parks has nearly stopped using it. Except in “Natural Areas.”

Recently, one of our supporters sent us these pictures:

It warned they would use Aquamaster (glyphosate) and Milestone (an astonishingly persistent herbicide) on the hillside above Islais Creek.


SF RPD should stop all use of Tier I chemicals. (Currently, the Natural Resouces Division uses Garlon and Roundup that are Tier I. ) The benefits are not worth the risk – to the public, their pets, and the people who apply herbicides.

We call on SF Rec and Park to stop using herbicides in our parks.

    More outrageous abuse of common sense….by the cult of “natural areas’
    What is natural about cancer-ogenic poisons?

    Who are the actual people perpetrating this sell-out to the chemical companies and putting us all at risk? It’s criminal, given what we NOW know about these chemical pesticides.

    Absolutely, they should stop using herbicides in our parks! I’d much rather see a few weeds if that is the choice.
