Hi, Susan.

Can you share links to some of these papers?

Thanks.

Be well.

Hi all.

I am wondering whether any of you might be able to speak to recent studies or findings related to glyphosate use in aquatic environments.  By this I am referring to use in riparian areas and floodplains as well as direct use in wetlands and waterways.

In the arena of invasive plant control, practice has often been based on the understanding that it is the surfactant that is impactful on aquatic life rather than the glyphosate itself.  However, as of late I am hearing more discussions, and seeing some papers, which would point to glyphosate -- no matter the formulation or added surfactants -- being a real problem in aquatic environments.

Have you seen (or written) papers that have isolated the impacts of glyphosate from other herbicide ingredients?

TIA,

Susan McLaughlin
