Hi Devii,  
 
I'm no biologist however, Ive read several small pieces on controlling Russian Knapp. Wondering out loud because I'm not a fan of 2,4 D (and Round Up), do you know of any studies where there was an attempt to drown this pesky weed?  
 
I'm part of a duck hunting club which is in a battle with this weed. We can control the levee and might be able push the infected area into a seasonally controlled pond, instead of draining that pond we can just leave it in the water for a season. Thoughts?

Here's a link to an abstract for a paper looking at aminopyralid (Milestone) to control Russian Knapweed: https://bioone.org/journals/Invasive-Plant-Science-and-Management/volume-1/issue-4/IPSM-08-088.1/Russian-Knapweed-span-classgenus-speciesAcroptilon-repens-span-Control-with-Low/10.1614/IPSM-08-088.1.short.  
 
That treatment worked well. Researchers I contacted have not tested drowning the plant.
